Description

The invention relates to a seat device for mounting on a watercraft, in particular a surfboard or stand-up paddle board (SUP board). By equipping the watercraft with the seating device, a universal rowing, paddling and motor device can be created. In particular, the seat device is designed as a modular system that can be supplemented with additional attachments.

Watercraft are used by people to move around on the water. In addition to well-known types of watercraft, such as rowing boats or inflatable boats, watercraft that essentially only have a simple floating body are also enjoying increasing popularity. These include in particular stand-up paddle boards (SUP boards). A SUP board is understood here as a surfboard with one or more fins, on which a user can stand and move forward in the water with the aid of a drive means to generate propulsion. In particular, it can be a surfboard with a large-volume floating body that offers sufficiently high tipping stability to ensure that the user can stand securely on the SUP board. In principle, however, within the scope of the present invention, a SUP board is not subject to any restrictions with regard to its dimensions or its volume. In particular, it is also possible to use these boards with several people. It can also be provided that the people stand or sit next to each other on the board. The boards can have the necessary width and/or length for this purpose.

In conventional standup paddling, which is enjoying growing popularity as a water sport, the athlete stands upright on such a SUP board and moves the SUP board forward by paddling using a paddle-shaped propulsion means. The side on which you paddle is changed regularly if a certain direction is to be maintained. This type of forward movement requires some skill on the part of the athlete to maintain balance on the SUP board while paddling and when changing sides to be paddled. Paddling is also strenuous and tiring, especially when longer distances are covered.

From the US 9,643,696 B1 discloses a seat assembly for a paddle board that includes a base with two parallel rails that are placed on the paddle board. A seat is also provided which has a frame which can be attached to the rails. A seat plate is also attached to the frame.

the U.S. 2005/0217555 A1 discloses a detachable propulsion attachment for a watercraft, in particular for a surfboard. The attachment includes a frame structure and a power unit that is detachably mounted to a transom. Furthermore, the frame structure includes a handle which is arranged at the front end of the frame structure and can be held by a user. The frame structure can be detachably fastened to the watercraft with the aid of connecting means. document US10065713B2 is considered the closest prior art and discloses the preamble of claim 1.

It is an object of the present invention to enable easy forward movement with a SUP board or other watercraft.

According to one aspect of the invention, the object is achieved by a seat device for mounting on a watercraft, which can in particular be a surfboard or SUP board. The seat device comprises at least one seat element for a user of the seat device and a support linkage. The seat element is detachably and/or pivotably connected to the support linkage. The seat device also has at least one receptacle and/or one fastening section for at least one drive means of the watercraft. The seat element has a seat part and a support part, the seat part having at least one mounting element for detachable attachment to a rear part of the support rod and the support part serving to support the seat part on the support rod or on a transport surface of the watercraft.

The seating assembly facilitates the forward movement of a watercraft in a variety of ways. On the one hand, the user can sit down on the seat element during a trip on the water, in order to avoid an exhausting standing position, for example over longer periods of time. For this purpose, the seat element can be supported by the support linkage above the bottom of the watercraft.

In addition, however, the seat device has at least one receptacle and/or one fastening section for a drive means. As a result, the use of the drive means can be made particularly easier for the user, for example by the user not having to hold the drive means himself, or at least not having to hold it completely. For example, the receptacle can serve as a mechanical guide for a manual drive means in order to make it easier for the user to handle the drive means. The receptacle can be used particularly advantageously as a fulcrum for the drive means, so that the user uses his muscle power comparatively efficiently with the help of the leverage into forward movement of the watercraft. Optionally, the user can also sit down while operating the drive means.

Another aspect of the seating device described is increased safety during use of the watercraft. For example, the seat device can also provide useful services for experienced users because the watercraft can be easily stabilized by shifting the center of gravity when the user sits on the seat element. This can be helpful in particular in the event of sudden changes in the weather, which can cause greater water movements and are therefore associated with an at least subjectively perceived increased instability of the watercraft. In such a situation, however, the user can sit down so that he does not have to worry about falling off the watercraft as a result of the increased instability.

As a further advantage of the seat device, the risk of losing the drive means is reduced if the drive means interacts with the receptacle and/or the fastening section and the user thereby at least does not have to hold the drive means completely himself. This can prove particularly beneficial in emergency situations. The demands on the user during a trip on the water can thus be reduced.

In addition, the seat device makes it possible to expand the user group for watercraft. For example, less experienced users or people with physical disabilities can also use a watercraft that they would not have used without the seat device. In particular, the willingness to stand permanently, which was previously required with SUP boards, is no longer absolutely necessary if a seat device according to the invention is used on the SUP board.

The detachable connection of the seat element to the seat device enables flexible use of the seat device. For example, the seat element can be removed before or during a trip on the water if no seat is required and the seat device is only to be used to hold the drive means. As a result, the space required by the seat device on the watercraft can be reduced as required, in order to further facilitate the forward movement of the watercraft. If the seat element is pivotably connected to the support linkage, it can, for example swivel upwards, whereby the space requirement of the seat device can also be reduced. The receptacle for the drive means can be detachably or permanently connected to the support linkage of the seat device.

A further advantage of the seat device, which is associated with the pivotability and/or detachability of the seat element, lies in the variable size of the seat device to facilitate transport and storage. In this way, the requirement for flexible use is taken into account in a special way. For example, SUP boards are often formed by inflatable floats, the size of which is varied by adding or deflating air to simplify transport and storage of the SUP board. Since the size of the seat device can also be varied by removing or pivoting the seat element, the flexible use of SUP boards and comparable watercraft is not impaired.

The drive means can be a belt. For example, the drive means can be a paddle with which the user can generate a forward motion for the watercraft by sculling. The receptacle of the seat device is preferably designed to receive a shank of the belt and can in particular be a oarlock. This may include a fork or a U-shaped piece forming the receptacle. In addition or as an alternative, a clamp can also be provided in order to be able to completely fix the drive means. The receptacle is preferably pivotably mounted on the seat device. As a result, the drive means can be optimally supported during use, while the drive means can still be moved freely for the most part. Furthermore, several receptacles can also be attached to different positions on the seat device, for example to the left and right of the central longitudinal axis of the watercraft. This enables flexible positioning of the drive means, and the user can choose a position that is ergonomically particularly favorable for him.

Furthermore, the drive means can be an outboard motor. The engine may be pivotable to affect a direction of travel of the watercraft. For this purpose, for example, the fastening section can be pivotably attached to the seat device. Alternatively, a rigid connection to the rest of the seat device can also be provided, in which case the user can influence the direction of travel, for example by using a belt in parallel, for example by immersing the rudder blade in the water.

The outboard motor can in particular comprise a drive element which is designed, for example, as a screw or propeller and which is motor-driven. As an alternative to a conventional internal combustion engine, in particular an electric motor can be provided in order to adequately take into account the desire for the lowest possible overall weight, which is widespread in water sports, in addition to ecological aspects. The electric motor can be powered by a separate energy store, e.g. a rechargeable battery or battery, which energy store can be located on the watercraft remote from the seat assembly to counterbalance the watercraft-mounted seat assembly with the outboard motor attached.

According to one embodiment of the seat device, the support linkage has at least one front part and one rear part, which can be pivoted relative to one another. This particularly favors flexible usability of the seat device. In particular, provision can be made for the seat device to be folded together relative to one another by pivoting the parts of the support linkage in order to facilitate transport and/or to reduce the space required for storing the seat device.

Furthermore, the seat element has a seat part and a support part, the support part serving to support the seat part on the support rods or on the transport surface of the watercraft. In this way, the assembly of the seat element and its structural design of the support linkage can be simplified. For this purpose it can advantageously also be provided that the seat surface part and the support part can be pivoted relative to one another. The seat device can then be transported or stored in a particularly space-saving manner.

According to a further embodiment, the seat part is designed as an elongate seat bench, the longitudinal extent of which extends in the longitudinal direction of the watercraft when the seat device with the seat part is mounted thereon. The transverse extent of the seat is preferably smaller than the transverse extent of the watercraft. This allows the user to sit "astride" or across the direction of travel on the bench.

In one embodiment, the seat surface part of the seat element has at least one mounting element for detachable attachment to the rear part of the support linkage. In particular, for example, attachment to a cross brace of the rear part can be provided. The seat part is preferably attached to the rear part in such a way that the attached seat part is aligned essentially horizontally. Furthermore, the seat part is preferably fastened to the rear part at a height that allows the user of the watercraft to sit comfortably on the seat part.

Each mounting element can comprise a clamping element which can be connected to the rear part of the support linkage, in particular to a cross brace of the rear part. Likewise, the mounting element can have a holding profile which partially surrounds a cross brace of the rear part. It preferably encompasses the cross brace from above, so that the seat surface part provided with the mounting element can be hooked into the cross brace. This enables easy assembly of the seat element on the support linkage. The wraparound is preferably as free of play as possible. For this purpose, the shape of the holding profile is preferably adapted to the cross-sectional profile of the cross brace.

The support part of the seat element can have at least one clamping element for attachment to the front part of the support linkage. As a result, a particularly stable attachment of the seat element to the support linkage is possible overall (by attaching the seat surface part and the support part). However, it can also be provided that the support part of the seat element itself is not attached directly to the support rods, but rather in a lower area on the transport surface of the watercraft or can be placed on the transport surface.

In a further embodiment, the seat part and/or the support linkage can be designed to be extendable. In particular, the length of the seat elements can be varied in this way. In an advantageous embodiment, this is achieved by a telescopic mechanism. For this purpose it can be advantageous to use telescopic rods. This allows small transport dimensions, in particular when dismantled, and at the same time enables the largest possible seat device when assembled. Furthermore, the seat device can be reduced during operation, e.g. to enable standing mode or to switch from standing mode back to sitting mode by pulling it out.

According to a further embodiment, the seat device can comprise a plurality of seat elements. In this way, the number of seats can be increased if necessary. The seat elements can each have a seat surface part and a support part, with the seat surface part of a first seat element having a mounting element for releasable attachment to a rear part of the support linkage, and with the seat surface part of a second seat element having a mounting element for releasable attachment to the first seat element, in particular on its seat part. The first seat element can thus, as previously described, be connected to the support linkage. The second seat element can be connected to the first seat element. The second seat element is positioned on the watercraft in front of the first seat element in the direction of travel. Advantageously, the second seat element also has a mounting element and the connection between the second and first seat element is established by means of the mounting element.

Furthermore, the seat part can have a seat and a frame surrounding the seat. In particular, the frame can be designed to at least partially encircle the seat surfaces. The frame can be connected to the seat surface in such a way that there is a gap between the frame and the seat surface all the way round or in sections. In these embodiments, when two seat elements are used, the second seat element can be connected to the first seat element by configuring the mounting element of the seat surface part of the second seat element as a holding profile which partially encompasses the frame of the seat surface part of the first seat element, in particular in the way it is previously described in relation to the making of the connection between the mounting member and the cross brace of the rear part of the support linkage. This means that both seat elements and in particular the assembly elements of their seat surface parts can be designed in the same way.

The seat element of the seat device can also be combined with one or more side benches, in particular when the seat surface part of the seat element is designed as an elongated seat bench. The side benches can each be attached to the side of the seat element. In this case, two side benches are preferably connected to the seat element on the left and right opposite one another in relation to the seat surface part. On a watercraft of appropriate width, side benches allow two users to sit next to each other in the direction of travel or longitudinally of the watercraft. The seat element, which is preferably designed as a bench in this case, is then located between the two users. The side benches can be used to provide each user with their own seat in multi-person operation. Furthermore, an optimal positioning of the user in relation to the center of gravity and/or the drive means can be achieved. This leads to improved stability of the watercraft and thus to increased safety.

It is still possible to mount only one side bench on one side. Furthermore, the side benches can be attached offset to one another on different sides.

Preferably, each side rail is provided with one or more support members for lateral support relative to the watercraft. The support elements can be attached to the side bench so that they can be folded or pivoted. The support elements support the side seat on the watercraft on the side that is not connected to the seat element, thereby increasing stability. The foldable or pivoting attachment allows the support members to be folded away when the side seat is not in use, making transport and storage of the side seat easier.

The side benches each have suitable assembly elements for connection to the seat element. If the seat element of the seat element has a surrounding frame, each side bench is preferably provided with at least one mounting element designed as a holding profile, which surrounds a lateral section of the frame in the manner already described. Thus, the side benches can be connected to the seat element in the same way as can be the case for connecting the seat element to the support linkage and connecting several seat elements to one another.

Preferably, one or more side benches can also each be provided with further receptacles for drive means, in particular for belts. In an advantageous embodiment, the drive means receptacles are connected to the side bench in a fixed or height-adjustable manner. The further receptacles are preferably arranged on the right and left in the direction of travel on one of two opposite side benches if they are attached to a seat part positioned on the watercraft. In particular, this allows the watercraft to be rowed using straps held in the receptacles. In particular, the receptacles for the drive means can be connected to the side seat by means of wing screws.

According to a further embodiment, the seat element of the seat device can be equipped with further receptacles for belts. In particular, in one embodiment, the seat device comprises several, in particular two, further mounts for drive means designed as belts, which can be connected to the seat element, with mounts being arranged on both sides of the watercraft when the seat device is equipped with a seat element with which the further mounts are connected, is mounted on the watercraft, and wherein the receptacles are held in particular by a linkage which is attachable to the seat member. These additional recordings allow the watercraft to be rowed with two oars while sitting. In an advantageous embodiment, the drive means mounts are displaceable on the seat element appropriate. This advantageously allows the drive means to be positioned ergonomically.

In further advantageous embodiments, the drive means receptacles are also held by a linkage that can be attached to the seat element. The common linkage holding the sockets prevents the drive means sockets from moving relative to one another. Advantageous positioning can thus be achieved in a simple manner. This allows the user to use both drive means evenly and also to easily align with the seating position and the center of gravity.

According to one embodiment, the seat device comprises a backrest element on which the receptacle and/or the fastening section are arranged. As a result, the drive means can also be conveniently operated by the user, for example, when he is sitting on the seat element. However, the driving means can also be used when the user is standing. In a connected embodiment, the backrest element is formed by a plurality of crossbars of the rear part of the support linkage, with the receptacle and/or the fastening section being attached to a connecting element which is connected to at least two of the crossbars. In this way, a backrest element is provided that allows the user to lean against it comfortably and at the same time allows the receptacle and/or the fastening section to be easily attached via the connecting element. Furthermore, the connecting element can optionally be connected to different cross braces. In this way, a height adjustment for the recording and/or the fastening element is created.

In principle, any fastening means or assembly means are conceivable for fastening the seat device to the watercraft. Although fastening the seat device to the watercraft offers advantages in many cases, this is not mandatory. For example, static friction between the support rods and the watercraft can represent a sufficient connection that defines an assembly option. A slip-reducing surface quality of the watercraft can contribute to this. The support linkage can be provided with suction cups or elements with an equivalent effect at its end sections, which interact with the watercraft, in particular in the use position, in order to provide a universally usable and detachable mounting option for the seat device.

One embodiment provides that the seat device, in particular the support linkage of the seat device, has at least one first fastening means which is designed to be complementary to at least one second fastening means attached to the watercraft, the seat device being able to be mounted on the watercraft in particular in a detachable manner by means of the first and second fastening means is.

In particular, one or more retaining pins can be provided on the watercraft as a second fastening means, which can be firmly connected to the watercraft. One or more plug-on elements of the seat device can be plugged onto the retaining pins and thus serve as second fastening means. The push-on elements can be formed, for example, by hollow sections of the support linkage. For example, at least end sections of the support linkage can be formed by hollow tubes that are slipped onto one or more retaining pins in order to mount the seat device on the watercraft in this way. Likewise, an eyelet can be provided on the watercraft as the second fastening means, which eyelet engages in an end section of a strut of the support linkage provided as the first holding means. For further attachment, a bolt can be passed through the end section and the eyelet.

The second attachment means can each be held by a flat piece which can be glued onto the watercraft or attached to it in some other way. The flat pieces can be attached to the watercraft in the appropriate positions using a template, for example. This allows a watercraft to be retrofitted with the second fastening means, so that the seat device can in principle be mounted on any watercraft. The flat pieces can be made of the same or a similar material as the surface of the watercraft.

It can also be provided that the support linkage has at least one end section with a slide-in slide as the first fastening element and at least one receptacle with a slide-in opening complementary to the slide-in slide is provided as the second fastening means on the watercraft, with the slide-in slide being able to be inserted into the slide-in opening in order to fasten the seat device to the to assemble the watercraft. The insertion direction preferably runs essentially parallel to the longitudinal axis of the watercraft, ie essentially horizontally and parallel to the direction of movement of the watercraft when traveling straight ahead. Preferably, the slide-in slide and opening are geometrically adapted to one another in such a way that there is an interference fit between the parts when the slide-in slide is received in the slide-in opening is. In order to enable the seat device to be securely fastened, the slide-in slide and/or the associated slide-in opening can in particular have a T-shaped cross section.

In a further embodiment, the seat device can be adjusted between a use position and a compact position, with the seat device extending essentially parallel to a transport surface of the watercraft when the seat device is mounted on the watercraft and brought into the compact position. This enables a particularly flexible use of the seat device, since it can also be brought into the compact position while the watercraft is being driven, if the user does not want any support from the seat device. In order to be able to bring the seat assembly into the compact position, the support linkage is preferably only partially mechanically connected to the watercraft so that the seat assembly can be adjusted between the use position and the compact position without completely detaching the seat assembly from the vehicle. For example, the seat device can be pivotable relative to the watercraft in the (partially) assembled state. The receptacle for the drive means can be used regardless of whether the seat device is in the use position or in the compact position. The same can also be provided for the fastening section. Alternatively, the receptacle or the fastening section can be usable depending on the respective position of the seat device.

According to a further embodiment, the support linkage of the seat device is provided with a lighting device which runs around the support linkage. The lighting device can include one or more LED lamps or an LED strip. Furthermore, the LED strip can illuminate the watercraft "slotted" or "rounded".

According to one embodiment, the seat device includes a seat heater. In particular, the seating element and/or the side bench described above can be equipped with seat heating. The seat heating is advantageously operated electrically. In one embodiment, the seat heater is designed as a heating coil. Advantageously, the accumulator for operating the seat heater can be positioned on the watercraft in such a way that it balances the weight of the seat heater and/or the seat device. The seat heating prevents icing on cold days and thus slipping on the seat device. Furthermore, the cooling of the user can be prevented.

According to a further aspect of the invention, a means of transportation is proposed which comprises a watercraft, in particular a surfboard or stand-up paddleboard, and a seat device according to one of the described embodiments that can be mounted in the area of a stern of the watercraft. Mounting the seat device in the rear area of the vehicle has proven to be favorable with regard to easy maneuverability of watercraft. However, it is also possible to arrange the seat device at other locations on the vehicle. Furthermore, it is conceivable to position several seat devices at different locations. In this way, several users can be seated at the same time, with the possibility that all or only individual passengers contribute jointly to the forward movement by means of respective drive means. The drive means can be of the same type or different.

According to a further embodiment, the drive means has an outboard motor, in which case, when the seat device is mounted on the watercraft and the outboard motor is attached to the fastening section of the seat device, the outboard motor can be at least partially submerged in the water in the area of the stern of the watercraft if the Watercraft floating on the water. Preferably, only a propeller and a propeller-carrying portion of the outboard motor are immersed in the water.

In principle, several drive means can be provided, whereby these can optionally also be used in parallel. For example, a belt and an outboard motor can be used in complementarity to make propulsion of the watercraft particularly easy or efficient. For this purpose, the seat device preferably has the receptacle and the fastening section. However, it is also conceivable that only one drive means is provided or only one drive means can be used simultaneously in connection with the receptacle or the fastening section.

According to one embodiment, the drive means can be at least partially submerged in the water in the area of the stern of the watercraft when the seat device is mounted on the watercraft. This can be the case regardless of whether the seat device is in the use position or in the compact position. As a result, the seat device can be used particularly flexibly with regard to one or more drive means. However, simplified applications can also be considered. For example, an outboard motor connected to the attachment section can automatically not (or no longer) be submerged in the water when the seat device is in the compact position is brought. Different possible uses can thus be combined with one another in order to optimize the number of possible uses or use cases considered to be sensible.

According to one embodiment, the seat device is mounted on the watercraft, in particular on a transport surface in the area of the stern of the watercraft. This can be implemented using the options described here, with a detachable coupling between the seat device and the watercraft also being a possible type of assembly.

According to a further embodiment, the watercraft also includes a compartment that serves as storage space. The compartment is embedded in the hull of the watercraft. In particular, the compartment is watertight lockable. The compartment allows personal items to be stored away from water. For example, the compartment can be used to safely stow away clothing.

In an advantageous embodiment, the compartment is arranged in the bow area of the watercraft in order to balance the weight of the seating device and/or drive means. This keeps the watercraft in a stable position. If it is a SUP board, the depth of the compartment can correspond to the thickness of a floating body of the SUP board, for example.

In a further embodiment, the compartment is designed in such a way that it can accommodate a fuel tank which can accommodate fuel for operating a drive means in the form of an internal combustion engine. The tank may be connected to the engine by fuel lines. In a further embodiment, the compartment is designed in such a way that it can accommodate a battery or accumulator for operating electrical consumers. This can in particular be a battery or an accumulator for supplying energy to a drive means designed as an electric motor. The battery or the accumulator can be connected to the motor by electrical supply lines. By storing the tank or battery or accumulator in the compartment, it is safely stowed away. Slipping and falling into the water can be prevented. Furthermore, there is more free space on deck.

In a further embodiment, the compartment is a cooling compartment that is operated with a cooling accumulator. In an advantageous embodiment, it is an electric refrigerated compartment and it contains an accumulator to operate the refrigerated compartment. Stocks, that are transported on deck or in an uncooled compartment would heat up considerably on warm sunny days and could spoil as a result. The refrigerated compartment prevents such heating, so that supplies can be safely transported under suitable conditions.

In a further embodiment, a bow rail can be attached to the watercraft. This has also proven to be advantageous for SUP boards, and it can also be provided to mount a spotlight on the railing. In one embodiment, the headlight can be controlled using a radio remote control, for example via a Bluetooth radio link, in order to allow a user positioned at the rear to operate it easily. Furthermore, position lamps can be mounted on the railing.

Overall, the invention and its aforementioned embodiments create a modular system with a seat device that includes a seat element and, if necessary, can be expanded to include additional seating such as additional seating elements and/or side benches. Furthermore, if necessary, recordings for different drive means and types of locomotion can be attached to the seat device.

figure 1 shows a trained as a SUP board 10 watercraft with a seat device 12 in the figure 2 is illustrated again in a perspective view. The board 10 is indicated only schematically in this figure and has an essentially three-dimensional rectangular shape, which can be viewed as a flat cuboid and is designed as a floating body. The surface of the board that faces away from the water during use forms a transport surface on which a user can stand, in particular on the board 10 . The seat device 12 is arranged in the area of the rear of the board 10 and is also positioned on the transport surface. The seat device 12 comprises a linkage 16 having a plurality of individual rods or struts, to which a seat element 14 can be attached, which offers a seat possibility for a user (not shown) of the board 10 . Furthermore, a backrest element 18 can be provided, which is firmly connected to the linkage 16 or integrated into it.

The linkage 16 of the seat device 12 has several struts with which it is fastened to the board 10 in the area of the rear. These struts are preferably connected to one another by one or more cross struts. In one embodiment (not shown in the figures), the linkage 16 is designed in the manner of a railing with a plurality of essentially vertical fastening struts and a cross strut connecting them. The linkage 16 can be approximately U-shaped and can be attached to the board 10 in the area of the rear edge and the rear lateral edge of the latter. The cross brace can be located approximately at seat height when the linkage 16 is attached to the board 10 .

The linkage 16 of the seat device 12 comprises a rear part 46 and a front part 44. The rear part 46 is arranged on the rear edge of the board 10, and the front part 44 in the rear lateral area of the board 10 when the linkage 16 is connected to the board 10 or .is placed on this. The rear part 46 and the front part 44 of the linkage 16 can be firmly connected to one another and in particular can also be designed in one piece. In this case, the front part 44 and rear part 46 can in particular each comprise one or more struts for attachment to or for placement on the board 10 . These can be connected to one another by one or more cross braces. In one embodiment, the linkage 16 is, as stated, overall U-shaped in the manner of a railing embodied with a plurality of essentially vertical fastening struts and a cross strut connecting them, with the lateral limbs of the U-shaped linkage 16 being formed by the front part 44 and the rear termination between the limbs being formed by the rear part 46 .

Likewise, it can be provided that the rear part 46 and the front part 4, as in the figure 2 shown, are connected to one another via a rotary joint 38 and can be pivoted relative to one another in an angular range. The angular range can be limited to a maximum angle between the rear part 46 and the front part 44 by a stop. The rear part 46 and the front part 44 each have lateral struts which are used in particular for attachment to the board 10 . The struts can run essentially parallel to one another and can be arranged on the left and right side of the board 10 when the seat device 12 or the linkage 16 is mounted on the board 10 . The distance between the respective struts of the rear part 46 and the front part 44 then determines the width of the seat device 12, which can correspond approximately to the width of the board 10 in its rear area.

The linkage 16 is preferably releasably mounted on the board 10 by means of fasteners 36 for the rear part 46 and/or fasteners 34 for the front part 44, wherein the fasteners 36 and 34 can be designed in various ways. In one embodiment, the fastening means 36 and 34 each comprise two base parts which are attached to the board 10 and which are provided with retaining pins. In this embodiment, the rear part 46 and/or the front part 44 have hollow sections which are pushed onto the retaining pins of the base parts in order to mount the linkage 16 on the board 10 . The hollow sections can in particular be hollow end sections of the struts of the rear part 46 or of the front part 44, which are pushed onto the retaining pins. In order to ensure that the linkage 16 is held firmly on the board 10, the retaining pins and the hollow sections can have a latching mechanism which engages when the hollow sections are pushed onto the retaining pins.

In a further embodiment, the fastening means 36 and 34 comprise receptacles with insertion openings attached to the board 10, and insertion slides are attached to the ends of the struts of the rear part 46 and/or the front part 44, which are each inserted into one of the insertion openings in order to secure the linkage 16 to be mounted on the board 10. The slide-in carriages and openings have mutually corresponding shapes so that a form-fitting connection is established between the parts when the slide-in carriages are received in the insertion openings. In particular, can the insertion slides and the associated insertion openings have a T-shaped cross section. Furthermore, locking means can also be provided in this embodiment in order to hold the slide-in slides in the slide-in openings, with the locking means snapping in in a suitable manner when the slide-in slides have been pushed into the slide-in openings with a specific insertion depth.

Furthermore, the fastening means 34 and/or 36 can also be designed in a different way. For example, they can be suction cups that are attached to the board-side ends of the struts of the front part 44 and/or the rear part 46 . In a further exemplary embodiment, the connection between the board 10 and the front part 44 and/or the rear part 46 can be established by means of a Velcro fastener. In this embodiment, for example, Velcro elements with barbs can be provided at the ends of the struts of the front part 44 and/or the rear part 46, which can be connected to Velcro elements with loops that are attached to the board 10.

In one embodiment, the front 44 and rear 46 portions of the linkage 16 are mounted to the board with associated fasteners 34 and 36 . Various attachment means 34 and 36 can optionally be used to attach the front part 44 and the rear part 46 . In particular, provision can be made for the rear part 46 to be mounted on the board 10 using the retaining pins or insertion elements described above, and the front part 44 to be mounted using suction cups or Velcro fasteners. This simplifies the attachment of the linkage 16 to the board 10 and at the same time ensures a sufficiently strong connection between the linkage 16 and the board 10 . However, provision can likewise be made for only the rear part 46 to be mounted on the board 10 with associated fastening means 36 or for only the front part 44 to be mounted on the board 10 with associated fastening means 44 . In these embodiments, the ends of the struts of the unattached portion of the linkage 16 may rest on the board 10 without further attachment. In this case, the stop for limiting the angular adjustment range between the front part 44 and the rear part 46 ensures that the linkage 16 is stable on the board 10.

The user can lean his back against the optionally provided backrest element 18 of the seat device 12 when he is sitting on the seat device. The backrest element 18 can in particular be formed by a plurality of transverse elements 19a-c, which extend between two side bars of the rear part 46. In a further embodiment, on the cross braces 19a-c on the side pointing in the forward direction In addition, a flat backrest part can be attached, against which the user can lean his back and which then forms the backrest element 18 together with the transverse elements 19a-c.

Also provided on the linkage 16 of the seat device 12 is a receptacle 26 for a belt 28 which has a shaft 30 and a blade 32 fixedly connected to the shaft 30 . The receptacle 26 can in particular be attached to the rear part 46 of the linkage 16 . If the seat device 12 has a backrest element 18 , it can in particular be mounted on a cross brace of the backrest element 18 . Figure 3a shows the seat device 14 with a strap 28 held by the receptacle.

The strap 28 can be attached to the standup paddle board 1 by means of the receptacle 26 in such a way that its shaft 30 is supported above the board 10 and can be rotated or pivoted about a fixed position. This allows the user to dip blade 32 of strap 28 into the water aft of board 10 (i.e., "aft") and propel board 10 by sculling. Here, propulsion is generated by moving the belt blade 32 back and forth in the water. In particular, the belt 28 can be moved in such a way that the belt leaf 32 follows a movement curve which corresponds approximately to a horizontal figure eight. During this movement, propulsion in forward direction is constantly generated. It is therefore a very efficient and simple way of generating propulsion.

The receptacle 26 for the belt 28 can be designed as an approximately U-shaped oarlock into which the shaft 30 of the belt 28 is inserted. The oarlock can be rotated about a vertical axis so that the belt 28 can be pivoted about this axis. The pivoting about a horizontal axis, which is also necessary when sculling, is made possible by a movement of the belt shaft 30 within the oarlock.

In a further embodiment, the receptacle 26 can have a holding element which firmly grips and fixes a section of the belt shaft 30 . Furthermore, the receptacle 16 can have a joint device, via which the holding element is connected to the (remaining) seat device 12 . The joint device preferably enables rotation of the belt 28 fixed in the holding element around a vertical axis and pivoting of the belt 28 around a horizontal axis, so that sculling movements can be carried out by means of the belt 28 fixed in the holding element. An exemplary embodiment of such a recording 26 is in the European patent EP 3 081 477 B1 described in more detail, to which reference is made in this respect.

Furthermore, a fastening element 20 is provided on the linkage 16, to which an outboard motor 22 can be attached. In particular, this can be a conventional internal combustion outboard motor. Alternative motors, such as electric motors, can also be installed in an advantageous manner. The fastener 20 may be releasably mounted so that it can be removed when the board 10 is not to be used with an outboard motor 29 . The fastener 20 may in turn be attached to the rear portion 46 of the linkage 16 . If this has the previously explained backrest element 18, it can in particular be attached to a cross brace 19ac of the backrest element 18, as in FIG Figure 3b illustrated.

Like in the Figure 3b Also shown schematically, the outboard motor 22 may comprise, for example, an underwater nacelle 23 housing a propulsion motor and a rotatable propeller 24 attached to the nacelle and capable of being driven by the propulsion motor. A shaft 25 can also be attached to the gondola, via which the outboard motor 22 can be mounted on the seat device 12 and which is aligned essentially vertically when the outboard motor 22 is used to generate propulsion.

In particular, in the case of an outboard motor 22 designed in this way, the fastening element 20 can be a support arm on which the shaft 25 of the outboard motor 22 is fixed. This can be done using suitable connecting elements between the shaft 25 and the support arm 22 . In one embodiment, the support arm can be pivoted about a vertical axis in order to pivot the nacelle 23 of the outboard motor 22 or the propeller 24 attached thereto and to change the direction of travel of the board 10 when it is driven by the outboard motor 22. Likewise, it can be provided that the support arm is non-rotatable and the shaft 25 of the outboard motor 22 is held pivotably on the support arm in order to pivot the nacelle 23 or the propeller 24 for the purpose of directional control.

In a further embodiment, the fastening element 20 can also comprise a mounting plate 40 which is arranged at the end of the support arm and which forms a transom. Such a mounting plate 40 is in the figure 1 illustrated with dotted lines. It allows the attachment of outboard motors 22, which are intended for mounting on the transom of a watercraft. This is in the Figure 3c illustrated. In particular, these outboard motors 22 can be clamped to the mounting plate 40 in a manner known per se. In order to control the direction of the board 10, the support arm on which the mounting plate 40 is attached can also be pivoted in this embodiment using suitable control means, or the outboard motor 22 can be pivoted on the mounting plate 40 and pivoted by the user using control means.

The drive motor of the outboard motor 22 is preferably designed as an electric motor that is supplied with energy by a rechargeable battery. The rechargeable battery can advantageously be placed on the board 10 and connected to the drive motor via connecting lines. The battery can be arranged in the forward direction in front of the center of gravity of the board 10, in particular in the area of the bow of the board 10, in order to at least partially compensate for the weight of the seat device 12, the outboard motor 22 and the user and to balance the board 10 better.

In order to connect the fastening element 20 for the outboard motor 22, in one embodiment a longitudinal element 17 is fixed to the rear part 46 of the linkage 16 on its rearward-facing side. If the fastening element comprises a carrier arm and if the carrier arm is intended to be pivoted for direction control, the connection between the longitudinal element 17 and the carrier arm is preferably designed to be pivotable. The longitudinal element 17 can be releasably attached to the cross braces 19a-c forming the backrest element 18, provided such a backrest element 18 is provided. In particular, the longitudinal element 17 can be connected to two transverse struts 19a-c arranged next to one another, for example with the aid of clamps which can be released by the user. By attaching the longitudinal element 17 to different pairs of transverse struts, a height adjustment for the belt 28 held in the receptacle 26 or for the outboard motor 22 connected to the fastening element 20 can be implemented. When using the strap 28, an adaptation to the body size of the user can thereby be achieved. When using the outboard motor 22, the immersion depth of the propeller 24 can be varied between a small immersion depth, which can be selected for example at shallow water depths, and a greater immersion depth, which can be selected at greater water depths. If no backrest element 18 is provided, the longitudinal element 17 can likewise be attached to one or more transverse struts of the support linkage 16 . In this case, the connection can also be released by the user

The receptacle 26 for the belt 28 can be pivotably fastened to the longitudinal element 17 at the upper end section, for example by means of a pin engaging in the longitudinal element 17 . This is also illustrated in the figures. Equally, however, the receptacle 26 for the belt 28 can also be fastened to the linkage 16 in a different way. An eccentric positioning of the receptacle 26 offset to the longitudinal element 17 can also be provided. Preferably, the fastening position can be flexibly selected by the user, so that the user can choose the fastening position that is ergonomically most favorable for him. Two possible mounting positions are in the figure 2 illustrated with dotted lines. For example, a suitable clamping and/or screw element can be provided for attachment, with which the receptacle 26 can be fixed at the desired attachment position on a cross brace of the linkage 16 .

Likewise, a plurality of receptacles 26 can also be provided, which can each be attached to a transverse strut of the linkage 16 in the manner described above, for example. The two receptacles 26 can be arranged to the left and right of the central longitudinal axis of the board 10. The user can then optionally use one of the mounts 26 as a strap holder and change the mount 26 used in each case while driving, for example if he wants to change his position on the board 10 .

The seat device 12 can also be equipped with a steering device 90 for controlling the outboard motor 29 . This is in the Figure 3d Illustrated as an example of an embodiment with a mounting plate 40 for attaching the outboard motor. The steering device 90 may include a handle releasably connected to the support linkage 16 . The steering device 90 is also connected to the outboard motor 22 or the mounting plate 40 in such a way that steering movements, which are executed as pivoting movements to the left and right, are transmitted to the outboard motor 22 . For this purpose, the handle can be attached, for example, to the longitudinal element 17 in such a way that the carrier arm of the fastening element 20, to which the outboard motor 22 or the mounting plate 40 is attached, can be pivoted using the handle. Furthermore, the steering device 90 may include a throttle lever 91 coupled to the motor to control the same. The coupling can be implemented, for example, with the aid of a Bowden cable, via which a throttle lever arranged on the motor 22 can be actuated.

Further, in one embodiment, the seat assembly 12 can be equipped with an optional armrest member 92 that is releasably connected to the support linkage 12 and includes armrests that can be positioned to the left and right of the user. For this purpose, the armrest element 92 can have a U-shape, for example. If the armrest element 92 is provided, the throttle lever 91 can also be arranged on one of the armrests instead of the steering device 90 .

Figure 3e FIG. 12 shows another embodiment in which the steering device 90 is connected to a rudder blade 93 in order to steer the board 10. FIG. The rudder blade 93 is attached to the support linkage 16 in such a way that it can be pivoted using the handle of the steering device 90 . For this purpose, it can be attached to the longitudinal element 17 via a rowing rod 94, or the longitudinal element 17 can also form the rowing rod at the same time. The movements of the steering device 90 are transmitted to the rudder blade 95 for this purpose. This allows the board 10 to be easily steered when propelled by one or more straps. Controlling with the help of the steering device 90 and the rudder blade 93 offers advantages in particular when the board 10 is used by several people, with one or more people rowing or paddling and another person merely steering. This can be the case, for example, when using the side benches 70 described below. Optionally, in addition to the steering device 91, an armrest element 92 with armrests for the user can in turn be provided.

In one configuration, the seat element 14 of the seat device 12 has a seat surface part 50 and a support part 52 which is pivotably connected to the seat surface part 50 . The seat element 14 is detachably connected to the linkage 16 as a whole. figure 1 shows schematically a seat element 14 detached from the linkage, which is provided for mounting on the linkage 16 in the area of the semi-square dashed line 58. When the seat member 14 is connected to the linkage 16 , the support member 52 is preferably at an angle of approximately 90° with respect to the seat bottom member 50 . When not in use, the seat element 14 can be folded relative to the seat part 50 due to the pivotability of the support part 52 in order to be able to store and/or transport it more easily.

Seat portion 50 is preferably approximately horizontal (parallel to board 10) when seat member 14 is attached to linkage 16. One or more mounting elements 54 can be attached in the rear region of the seat surface part 50, which are used for attachment to the linkage 16. The rear part 46 of the Linkage 16 include a cross brace 53, with which the mounting elements 54 are connected. If a backrest element 18 is provided, the transverse strut 53 can be arranged in relation to the vertical direction approximately in the central region of the rear part 46 below the transverse struts 19a-c forming the backrest element 18 at a comfortable seat height for the user. If the support linkage is designed in the manner of a railing, the seat surface part can be fixed to it by means of the mounting elements 54 .

Each mounting member 54 may include a clamp member that is snap-connectable to the cross member 53 of the rear portion 46 of the support linkage 16 . Likewise, it can be designed as a holding profile that encompasses the cross brace 53 from above. As a result, the seat surface part 50 provided with the mounting element can be attached to the cross brace 53 in a simple manner. The shape of the holding profile is preferably adapted to the cross-sectional profile of the cross brace 53 . In particular, the hollow profile can have an angular or round U-shape if the cross strut has a round or rectangular cross section.

The seat part 50 can in particular be designed as an elongate seat bench, the longitudinal extent of which extends in the longitudinal direction of the board 10 when the seat device 12 with the seat part 50 is mounted thereon. The transverse extent of the bench seat is preferably smaller than the transverse extent of the board 10. In particular with this configuration of the seat surface part 50, it can be designed to be extendable. The pull-out mechanism can provide that the seat part 50 consists of two elements that can be pushed into one another. In an advantageous embodiment, the pull-out mechanism is a telescopic mechanism. The seat element 50 can be designed analogously to a telescopic rod.

The support member 52 can also be connected to the linkage 16 . For this purpose, clamping elements can be provided in the lower end area of the support part 52, with which the support part 52 can be fastened to a transverse strut of the front part 44 of the linkage 16 located in this area. In a further embodiment, the support part 52 itself is not attached to the linkage 16, but stands directly on the surface of the board 10. Optionally, it can also be provided that in the lower area of the support part 52 suction cups or Velcro elements for attaching the support part 52 to the Board 10 are provided.

In a further embodiment (not shown in the figures), the seat element 14 can also be formed by a single flat seat part 52 which can be connected via a rotary joint is connected to the linkage 16, in particular to its rear part 46. The movability of the seat part can also be restricted by support elements provided on the front part 44, so that the seat part cannot be pivoted beyond the support elements in the direction of the board 10. In this embodiment, the linkage 16 and the seat element 14 of the seat device 12 resemble a folding chair in terms of their structure and their function.

The seating device 12 configured in the manner described above can optionally be mounted on the board 10 if the user desires support from the seating device 12 . Likewise, the user can use the board 10 without the seat device 12 in a conventional manner and can remove the seat device 12 from the board 10 for this purpose. Since the seat element 14 can be detached from the linkage 16 or pivoted in relation to the rear part 46, the seat device 12 can be easily transported when not in use and stowed away with little space requirement. For this purpose, the seat element 14 can be detached from the linkage 16 and likewise folded up, or it is pivoted until it rests against the linkage 16 . If the linkage 16 has a front part 44 and a rear part 46 movable relative thereto, the front part 44 can be pivoted in the direction of the rear part 46 until it rests against the latter, in order in this way to further reduce the space requirement during transport and storage.

In an embodiment in which the linkage has a front part 44 and a rear part 46 movable relative thereto, it is also possible to convert the seat assembly 12 from an in-use position to a compact position when it is mounted on the board 10 . As a result, the board 10 can also be used with the seat device 12 attached thereto without its support. In order to bring the seat device 12 into the compact position, pivoting between the front part 44 of the linkage 16 and the board 10 or between the rear part 46 of the linkage 16 and the board 10 is made possible. This can be achieved, for example, by joints which are arranged on the fastening means 34, 36 of the part 44, 46 which can be pivoted in this way, or on the struts of this part 44, 46. The relevant part 44, 46 also remains connected to the board 10 in the compact position. In order to bring the seat device 12 into the compact position, the other part 44, 46 is detached from the board 10 and pivoted onto the part 44, 46 which is still connected to the board 10. Both parts 44, 46 are then pivoted onto the board 10 via the aforementioned joints and placed on the board 10 in this way. Optionally, an outboard motor attached to the seat assembly 12 can be used 22 are pivoted here with. The seat member 14 can be detached from the linkage 10 when placed in the compact position or pivoted onto the rear portion 46 so that the front 44, rear portion 46 and seat member 14 are substantially parallel to each other and placed on the board 10 be able.

In the context of the exemplary embodiments explained above, the seat device 12 is attached to the board 10 in the area of the rear. This is particularly advantageous when the seat device is used in conjunction with an outboard motor 22, the screw 24 is immersed behind the board 10 in the water. And even when using a belt 28 as the drive means, positioning in the rear area has proven to be favorable with regard to easy manoeuvrability. However, it may also be possible to position the seat assembly 12 at other locations on the board 10 at the user's option. For this purpose, the board 10 can be provided with fastening means at different positions, which enable the seat device 12 to be fastened in the manner described above. Even in these positions, the seat assembly 12 can be used to support a belt 28 used as a drive means. The belt 28 can be immersed in the water approximately to the side of the board 10 in order to generate propulsion.

As in figure 4 is illustrated schematically, it is also possible for a further seat device 12' to be attached to the board 10 in the forward direction in front of the seat device 12 arranged in the rear area, so that several users can sit at the same time or are supported by seat devices 12, 12'. The further seat device 12 ′ can be designed like the seat device 12 in one of the configurations described above. In this constellation, the rear seat device 12 can be used to hold a drive motor 22 (as illustrated in the figure), or also to hold a belt 28 used as a drive means. The front seat device 12' is not used to hold an outboard motor 22 and is therefore preferably not used the fastener 20 is used. In principle, however, it can be used to hold a belt 28, which is then immersed into the water approximately to the side of the board 10 in order to generate propulsion. For this purpose, the front seat device 12' can be equipped with a corresponding receptacle 26, which can be attached to the upper transverse strut 19a of the backrest element 18 in the manner described above. Equally, however, the front seat device 12' can also be used as a pure seat without a drive means held by it.

Like in the figure 5 is shown schematically, it can also be provided that a seat device 12 is provided with two seat elements 14 and 14 '. These can be designed in the manner described above and in particular each have a seat surface element 50 and a pivotable support element 52 . The rear seat element 14 in the direction of travel is connected to the support linkage 16 of the seat device 12 . As previously described, the connection may be made using one or more mounting members 54 attached to the seat member. The front seat member 14' is connected to the rear seat member 14 at the front end thereof. Again, this connection may be made using one or more mounting members 54 attached to the front seat member 14'. The support elements 52 of the seat elements 14 can be connected to the board 10 as described above. In further embodiments, more than two seat elements connected to one another can also be placed on the board 10 .

In a further embodiment, which is shown schematically in FIG figure 6 As illustrated, the seat member 14 is provided with a further fastener 60 for straps. The fastening element 60 is designed in such a way that the straps can be held laterally to the board 10 . For this purpose, the fastening element 60 comprises a transverse strut 61, at the ends of which receptacles 26 for the belts are arranged. These can, for example, each be attached to a further strut 62 which points horizontally upwards from the cross strut 61, but can also be attached in any other direction. Other directions, such as 45° forward, allow for improved power transfer. The receptacles 26 can in turn be designed as oarlocks.

In an advantageous embodiment, the fastening element 60 is slidably fixedly mounted on the seat element 14 . In this case, the fastening element 60 can be attached to the seat surface element 50 and, for example, completely or partially surround it. In another embodiment, the fastener 60 slides on one or more guide rails that are part of or attached to the seat panel 50 .

In particular, the seat element 50 can comprise a seat surface 50b and a frame 50a. The seat 50b is designed as a flat element on which the user can sit. In order to increase the seating comfort, the seat surface 50b can also be provided with a suitably designed upholstery. The frame 50a can be designed to run around the seat surface 50b. Furthermore, advantageously the frame 50a can be connected to the seat surface 50b in such a way that there is a gap between the frame 50a and the seat surface 50b at least in sections.

In particular, when the seat element 50 is designed as an elongated bench seat, it can in a configuration that is shown schematically in FIG 7 shown, one or more side benches 70 can be mounted. Each of the side benches 70 allows a user to sit on a sufficiently wide board 10 on one side in the direction of travel. The side benches 70 are preferably used in pairs, with the side benches of a pair being attached to the seat element on the left and right opposite one another. This usage is also in the figure 7 illustrated. Each pair then allows two users to sit side by side on a sufficiently wide board 10.

In one embodiment, each side bench 70 comprises an upper side bench part 71 and at least one support element 72 . The upper side bench part 71 serves as a surface for sitting and can be connected to the seat element 50 . The upper side bench part 71 can be configured similarly to the seat element 50. In particular, the upper side bench part 71 can comprise a flat seat part on which a user can sit. To increase comfort, the seat part can be provided with padding. Furthermore, the upper side seat part 71 can also include a frame that supports the seat part.

The support element 72 serves to laterally support the side bench 70 and is placed on the board 10 or mounted on it. This can be done in the same way as previously described in relation to the support element 52 of the seat part 50 . Furthermore, it can be provided that the support element 72 can be pivoted relative to the upper side bench part 71 . For this purpose, one or more suitable joints 73, for example hinge joints, can be provided on the support element 72. As a result, the support element 72 can be folded in when the side bench 70 is not in use, in order to enable space-saving transport and to simplify storage. Preferably, the support member 72 is also formed in multiple pieces and includes two legs that are pivotally attached to the upper seat bench portion 71 . This configuration is also in the figure 7 illustrated.

At least one mounting element 74 is preferably provided on the upper side bench part 71 for attachment to the seat surface element 50 . If the seat element 50 has an at least partially surrounding frame 50a and there is a gap between frame 50a and seat surface 50b at least in sections, which gap extends laterally along seat surface element 50, mounting element 74 can be configured in the same way as mounting element 54 of seat surface element 50 and include a retaining profile that partially surrounds the frame 50a. A leg of the retaining profile then engages in the gap between the frame 50a and the seat 50b. This allows the side bench 70 to be easily hung on the frame 50a.

Figure 7a 12 shows the side benches 70 with additional drive means receptacles 75. These can be detachably mounted on the side benches 70. To do this, they can be attached to the side benches 70 using wing nuts. In particular, the drive means mounts 70 can each be connected to the frame of a side bench 70 . The drive means receptacles 75 can in particular comprise an oarlock 26 in order to receive a belt.

In addition, the board 10 can be provided with a compartment, which offers advantages in particular when the board 10 is used together with the seat device 12 . figure 8 shows a schematic representation of such a compartment 81 in a top view (the seat device 12 is not shown for reasons of clarity). The compartment 81 is preferably arranged in the bow area of the board 10 and embedded in the floating body 80 of the board 10 . The compartment 81 can extend to the bottom of the floating body 80 . In one embodiment, a bottom plate of the compartment 81 can in particular take the place of the outer shell of the floating body 80 in the area of the compartment 81 . In a further advantageous embodiment, the compartment 81 is less deep than the floating body 80b and is therefore only let into it from above. For example, the float 80 could be provided with a recess allowing the compartment 81 to be lowered from above. For this purpose, the compartment 81 can be provided with a peripheral seam 84 which is connected to the surface of the floating body 80 of the board 10 . Likewise, if the compartment 80 has the same depth as the float 80, the bottom of the compartment 81 may have a peripheral seam which is connected to the underside of the float 80. When the board 10 is configured as an inflatable SUP or surfboard with one or more air chambers, the compartment can replace an air chamber or a part thereof. For this purpose, the compartment 81 is connected to the floating body 80 in an airtight manner.

The compartment 81 can serve as storage space and for this purpose can be closed watertight with a cover (not shown in the figures). In this embodiment, the user can store personal items protected from water. For example, compartment 81 can be used to safely stow away clothing. Compartment 81 can also be a battery powered cooler compartment for storing supplies and keeping them cool in warm weather.

In another embodiment, the compartment 81 is configured to receive a fuel tank capable of holding fuel to operate an outboard motor 22 configured with an internal combustion engine. The tank may be connected to the outboard motor 22 by fuel lines. In a further embodiment, the compartment 81 is designed in such a way that it can accommodate a battery or an accumulator for operating the electrical consumers. This can in particular be a battery or an accumulator for supplying energy to an outboard motor 22 equipped with an electric motor. The battery or the accumulator can be connected to the outboard motor 22 by electrical supply lines.

Furthermore shows 8 a bow rail 85 attachable to the board 10. Like in the Figure 8a illustrated, navigation lanterns 86, 87 can also be mounted on the bow railing 85, for example. These may be separate port and starboard lanterns 86 and 87. A navigation light containing both lamps can also be used. This can then be mounted in particular on the middle of the railing 85 . Furthermore shows Figure 8b for example a bow railing 85 on which a headlight 88 is mounted. Moreover shows Figure 8c a railing 85 on which an LED lamp 89 for illuminating the board 10 is mounted. In particular, the LED lamp 89 can illuminate the board 10 continuously or "slotted". The LED lamp 89 can be designed as an LED strip.
