Description

  The present invention relates to a simple marina device for leisure boats, fishing boats, recreational fishing boats and other small vessels, and more particularly to a simple marina device capable of managing and operating these vessels without requiring landing work.

Except for leisure boats, recreational fishing boats, jet skis, fishing boats, and other small vessels that leave every day like a full-time fisherman, when they are not in use, they are unloaded and contracted to the marina for storage management. It is normal. When the ship is not used, if it is kept at sea as it is, barnacles and oysters adhere to the bottom of the ship and the side of the shore, resulting in great resistance when traveling and drastically lowering the speed of the ship. However, when consigning to a marina, along with the annual consignment contract fee, every time it is used, the crane pays a lifting / lowering fee, which is a large expense added to the ship body cost for leisure and leisure use, and is expensive. In addition, when it is crowded, it takes time to lift and lower the ship body at the marina, and it may not be in time for the estimated arrival time according to the purpose of use. Further, when using a ship entrusted with storage to the marina, it is necessary to make a telephone call in advance on the day before the scheduled date of use or to perform check-in and check-out procedures. In view of the above, Japanese Patent Application Laid-Open No. 6-255581 has proposed a ship bottom antifouling method for preventing barnacles and seaweed from adhering to the ship bottom during mooring without landing or the like. .
Japanese Patent Application Laid-Open No. 6-255581 (paragraph number 0006, claim 1, FIG. 1)

  In the above conventional antifouling method for the bottom of a ship, when mooring a ship or a floating pier, a ship bottom cover in which weights are attached to the outer peripheral edge of the water-tight sheet at a predetermined interval is installed in the longitudinal direction of the bottom of the ship or the floating pier. Cover the entire bottom of the ship with a predetermined distance from one side of the ship toward the other side of the bottom of the ship, and cover the outer periphery of the ship's bottom cover from the water line while holding seawater between the ship bottom cover and the ship bottom. The ship is lifted upward by a predetermined dimension and locked to block the ship bottom from contact with the seawater flow. However, this method involves success or failure in covering the entire ship bottom by passing the ship bottom cover over the ship bottom, and is not easy without certainty. Therefore, not only labor, labor and time are required, but also the operation of locking the outer periphery of the cover to the outer edge of the hull after covering the entire bottom of the ship is complicated and requires time and effort. Further, when leaving the ship, it is necessary to remove these bottom cover, which takes time, and there is a problem that it is difficult to deal with when leaving the ship, which is often rushed. Also, since barnacles and oyster shells are attached to the outer surface of the ship bottom cover, it is necessary to clean this cover, and it is necessary to carry out operations such as landing, cleaning and drying. Facility was needed. Furthermore, after covering the entire bottom of the ship, work such as locking the outer periphery of the cover to the outer edge of the hull requires the presence of a floating pier that serves as a gentle approach from the quay to the water surface. There was a problem that expensive equipment cost was required and lacked practicality.

  The present invention has been made in view of the above-described conventional problems, and one object of the present invention is to prevent adhesion and contamination of a ship's bottom and the like at a low cost without depending on marina facilities and facilities. In addition, it is an object of the present invention to provide a simple marina apparatus and a ship management method that are excellent in practicality and can be shipped and stored in a port in a short time. Another object of the present invention is to provide a simple marina apparatus and a ship management method that do not require time and effort in use and little maintenance of the apparatus itself.

  In order to achieve the above object, the present invention includes a float 12 that is installed on the water so that it can be lifted and lowered using buoyancy, and the hull BD is placed at the time of rising to raise the bottom BT to a position higher than the water surface. And a simple marina device 10 characterized by comprising a float buoyancy adjustment drive means 14. Any float may be used as long as it has a structure that floats on water by buoyancy, and it may be a synthetic resin foam or wood molded into an arbitrary shape using a buoyancy body. The case body may be a hollow case body, and the air inside may be used as a buoyancy source. In that case, the case body material is a synthetic resin molded body having strength and durability such as FRP, wooden, metal It may be configured by selecting a material such as made, strength-maintaining and surface water repellent paper.

  At that time, the float 12 may include a case body 12A, 12B having a hollow inside, and the buoyancy may be adjusted by filling and discharging the floated water into the float. Unlike direct filling and discharging of air into the hollow part of the float, filling and discharging water that does not require expansion and contraction and does not require airtightness is a good and reliable response when adjusting buoyancy. Is advantageous.

  Further, the buoyancy adjustment drive means 14 may include drive means (38) for forcibly filling and discharging water into / from the float 12. For example, by using a commercially available pump, it is possible to easily fill and discharge the water if the head is about the height of the deck from the water surface. Moreover, the water can be discharged out of the ship as it is, and can be taken in from the outside of the ship and used.

  The buoyancy adjustment drive means 14 includes water supply / discharge pipes (42, 48) connected at one end to the inside of the float 12 and the other end always protruding from the water surface WL and connected to the water charge / discharge drive means. Good. While maintaining the structure for adjusting the buoyancy of the float through the water supply / discharge drive, the drive device such as a pump can be easily connected to the pipes, and the pipe ends are simply opened. The air venting function can also be performed.

  Moreover, it is good to provide the contact | abutting support means (22) supported by the float 12 and opening a gap | interval from a float main body and supporting the ship BD directly.

  Further, the float 12 may be provided with an introduction index 32 for introducing the hull BD to the correct placement position. It is preferable to use a visual confirmation such as a pole or a flag, but it is even better to use a voice or satellite location confirmation system.

  Further, the float 12 may be held in the water at a required position by the rope 56 stretched between the land side and the underwater side.

  Further, the float 12 may be moved between the required position and the land by operating the rope 56 from the land side.

  Further, the float 12 may be provided with a descent limit holding means (122) so as not to descend below the predetermined position of water.

  Furthermore, the float 12 may be formed of a structure in which a plurality of float bodies are connected and integrated in a state of being separated from each other, and is not limited to a structure that is assembled in a twin body shape, but is U-shaped, V-shaped or any other shape As good as Further, the number of float bodies may be connected in a combination of 2, 3, 4, or more, so that the ship body can be placed effectively and stably.

  Further, the present invention uses a buoyancy to place a float on the water so that the float can be raised and lowered, and when the float is lowered in the water, the ship enters and stops at the position above the float. It is comprised from the management method of the ship characterized by raising a bottom part to a position higher than a water surface, maintaining the state which lifted the ship, and managing a ship.

  A simple marina device of the present invention is a float that is installed on the water so that it can be lifted and lowered using buoyancy, and the hull is placed at the time of ascent and the bottom is raised to a position higher than the water surface, and a float buoyancy adjustment drive means; With this configuration, the buoyancy adjustment drive is used to move the ship in and out while the float is descending underwater, and when managing and storing, the float is simply driven up so that the bottom of the ship is lifted from the water surface to a high position. Well, the transition between ship use and storage management is extremely easy and can be done in a short time without labor, and it does not incur marina storage charges and hull lifting charges at low cost. Maintenance can be performed.

  In addition, the float includes a case body having a hollow inside, and is configured to adjust the buoyancy by filling and discharging the floated water into the float, thereby filling the float with water. Because the buoyancy is adjusted by adjusting the amount of air in the float due to the discharge, unlike the case of air pressure feeding, suction, etc., there is no need to air-tighten the inside of the float, and there is almost no expansion and contraction, so buoyancy adjustment is reliable Moreover, it can be carried out in a short time, and it is highly practical because it greatly improves the preparation for leaving and leaving the port and the storage workability.

  In addition, the buoyancy adjustment driving means includes a driving means for forcibly filling and discharging water into and out of the float, so that buoyancy with good responsiveness can be obtained by filling or discharging water into the float. The adjustment drive can be effective.

  In addition, the buoyancy adjustment driving means includes a water supply / discharge pipe connected to the water filling / discharging driving means with one end communicating with the float interior and the other end protruding from the water surface at all times. Water filling and draining work from / to the ship's pump and water supply / discharge pipe requires less labor and can be done in a short time. The water supply / discharge pipe also supplies and discharges water. It can also function effectively as an air vent from the inside of the float.

  In addition, by adopting a configuration in which contact support means is provided that is supported by the float and opens a gap from the float body to directly contact and support the ship, the ship body directly contacts the float housing and the float or No damage to the bottom of the ship.

  In addition, the float has a structure in which an introduction index for introducing the hull to the correct placement position is installed, so that the ship can be stopped at a limited position on the upper surface of the float installed on the water, and the guidance function is provided. Therefore, it can be performed reliably in a short time.

  In addition, since the float is configured to be held in the water at the required position by a rope stretched between the land side and the underwater side, the tide level and the ups and downs and fluctuations caused by the waves through the loose support state by the rope. It can respond flexibly to movement and can realize stable management of water in and out of the ship.

  In addition, the float is constructed so as to be able to move between the required position and the land by manipulating the rope from the land side, so that it can be supported on the water by the rope and to the ship from the quay side. Can be accessed smoothly.

  In addition, the float is provided with a descent limit holding means so that it does not descend below the predetermined position of the water, so that the float fills with water against sudden buoyancy adjustment fluctuation action by a pump or the like. However, the float body can be prevented from sinking below the required height position, and buoyancy adjustment can be performed smoothly and easily without paying attention to fine buoyancy adjustment. Moreover, the work and processing at the time of leaving a ship and returning to a port can be completed in a short time.

  In addition, the float is composed of a structure in which a plurality of float bodies are connected and integrated in a state of being separated from each other, thereby allowing various configurations of the float itself to stably mount the hull on the float. It can be arbitrarily designed in the combination connection form.

  Further, according to the ship management method of the present invention, the float is placed on the water so that it can be lifted and lowered using buoyancy, and the ship enters and stops at the position above the float when the float is descending in the water. The buoyancy of the ship is lifted to raise the bottom of the ship to a position higher than the surface of the water, and the ship is kept in the lifted state to manage the ship. It is only necessary to maintain the state where the ship bottom is lifted to a high position from the surface of the water, and the transition work between the use of the ship and the storage management is extremely easy and can be performed in a short time without labor, and the marina. It is possible to maintain and manage the ship at low cost without incurring storage charges and hull lifting / lowering charges.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. The simple marina apparatus and the ship management method of the present invention are a water-mounted simple marina apparatus and a ship management method that enable a ship to be used and stored without using a land marina facility. The present embodiment can be deployed not only in lakes, ponds, etc., but in the present embodiment, an example in the case of installation in a bay on the coast of the sea area will be described below.

  1 to 7 show a simplified marina apparatus according to an embodiment of the present invention. In FIGS. 1 and 2, the simplified marina apparatus 10 includes a float 12 and a buoyancy adjustment driving means 14 of the float 12. I have. The float 12 is a buoyancy up-and-down moving means that is installed on the surface of water (hereinafter referred to as “the sea”) so as to be lifted and lowered using buoyancy, and moves up or down with respect to the sea surface by adjusting the buoyancy. The float 12 itself may be of any structure as long as it can increase buoyancy. For example, the float 12 may be formed into a structure that can be filled with foam and loaded or supported by a ship. In the form, it is comprised from the hollow case body which performs buoyancy adjustment with the air quantity in a hollow. In this embodiment, the float 12 has an integral catamaran structure in which hollow case bodies 12A and 12B that are long in one direction are arranged so as to be parallel to the longitudinal direction with a gap in the middle, and are integrally assembled. One hollow case body is formed of a hollow box body having a substantially quadrangular cross section and hermetically closed as a whole. And in the simple marina apparatus of this embodiment, the volume corresponding to the occupied space of the air in the hollow case body is changed by filling and discharging the water floating in the float 12 into the float, thereby the float 12 The whole buoyancy is moved up and down. In the present embodiment, the hollow case bodies 12A and 12B that form the float 12 are made of a material that is lightweight and excellent in strength and durability, such as FRP (fiber-reinforced plastics) fiber reinforced plastic.

  In the present embodiment, the float 12 is provided with an auxiliary float portion. That is, the float 12 includes a main float part 121 and an auxiliary float part 122. The auxiliary float unit 122 is a descent limit holding means that holds the float 12 at a set descent limit position so that the entire float 12 does not descend or sink below a predetermined height. Even if the main float unit 121 is completely filled with water, the auxiliary float unit 122 is assisted. The float 122 has a structure that prevents water from entering. For example, the main float part 121 and the auxiliary float part 122 may be formed as separate independent chamber structures that are hermetically sealed by walls, but in the present embodiment, both are in communication. That is, the upper surface wall 121UW of the hollow case body 12A (B) has a flat surface portion that is flush with the water surface and stabilizes the entire hollow case body in a naturally floating state without applying external force. An auxiliary float portion 122 protruding upward and sealed from the external space is formed integrally with the main float portion. Accordingly, when water is supplied from the main float part 121 side, the water level does not rise above the lower surface of the upper wall 121UW of the main float part 121 in the hollow chamber, and the hollow case is more buoyant than the buoyancy corresponding to the air volume in the auxiliary float part 122. The entire body is held at a predetermined height in water. In the present embodiment, the auxiliary float portion 122 is further formed in a stepped box shape having a plurality of kicking surfaces, so that the transfer from the ship to be stored can be performed on the stepped portion on the upper surface side. It can be used safely for getting on and off, and it is convenient for checking the stop position of the ship and other inspection work.

  As shown in FIGS. 1 and 2, the two hollow case bodies 12A and 12B are constructed by connecting and fixing a metal frame 18 at two locations near the front and rear in the longitudinal direction of the hollow case body. It is configured as a trunk structure. One metal frame 18 is placed on the upper surface wall 121UW of the main float portion 121 on both the left and right sides and joined and fixed to the opposite side wall 121SW, and hangs downward. It is configured to be integrally connected by the handing rod 20 arranged in the above. The metal frame 18 is a main connecting element for assembling and connecting both the hollow case bodies 12A and 12B in a double-trunk structure. In the present embodiment, for example, a material obtained by bending and lowering a stainless steel long plate is used. The metal frame 18 and each hollow case body are connected to each other by being fixed with screws at a plurality of points, for example. In the present embodiment, the hollow case bodies 12A and 12B are configured as a shape in which the opposing wall side is cut away obliquely downward in a cross section. Then, a contact receiving mechanism 22 is installed by being supported by the passing bar 20.

  The contact receiving mechanism 22 is contact support means that is supported by the float 12 and that directly supports the ship by opening a gap from the float body. In this embodiment, as shown in FIG. A contact plate 24 that comes into close contact with the contact plate 24 and a contact state adjusting device 26. The contact condition adjusting device 26 has a rising rod 28 that is erected upward at two spaced points of the passing rod 20, and a lower end side of a plurality of retaining holes (not shown) provided in the passing rod 20. Bolts are fixed at appropriate positions. Further, the upper end side pivotally supports the contact plate 24 via the pivot shaft 30 at an intermediate position of the contact plate 24, so that the contact plate 24 can swing around the pivot shaft 30. It has become. A cushion member such as a rubber plate (not shown) is stretched on the upper surface of the contact plate 24. As a result, the contact plate 24 is in close contact with the ship in the width direction of the hull in FIG. Therefore, the hull is prevented from coming into direct contact with the float 12 to cause damage or breakage of the float. By the contact receiving mechanism 22, the hull BD is placed when the float 12 is raised, and the bottom BT is lifted to a position higher than the water surface.

  Further, in FIG. 1, the float 12 is provided with an introduction index 32 for introducing the hull to the correct placement position. The introduction index 32 is a guide means for stopping the hull at the correct use position of the simple marina device, which is a management position such as in a bay, especially when the ship returns to the port. In the embodiment, the introduction index 32 is left and right from the outer surface side of the float 12. It is composed of two poles that are formed in front and back. The user inside the ship that returns to the port and anchors controls and stops the bow so that the bow enters the middle part of the poles on both sides as shown in FIG. In addition, the support position of the hull in the longitudinal direction of the hull is pre-marked on the hull in advance indicating the optimal support position considering the hull center of gravity set at the time of design. It is set. As a result, the hull is surely positioned at the vertical movement position of the float, and the simple management and operation of the ship by the float buoyancy adjustment drive can be achieved.

  As shown in FIGS. 1 and 2, in the present embodiment, a stabilizing plate 33 is formed to project outward from the bottom of the hollow case bodies 12A and 12B. The stabilizing plate 33 is formed to protrude outward from the outer wall 121GW, and stabilizes the entire float by suppressing the oscillation caused by the waves with the resistance of water. In the figure, 35 is an inspection port.

  As shown in FIG. 2, the hollow case bodies 12 </ b> A and 12 </ b> B of the float 12 are communicated with each other by a communication pipe 34 that communicates the inside at two positions near the front and rear. The communication pipe 34 is an air amount balance means for maintaining the same amount of water to be filled therein so that the amount of air in the left and right floats of the twin cylinders is equally maintained, and in the embodiment, each hollow case body 12A. , 12B, the positions near the lower end of the opposing side wall 121SW are communicated with each other by a hard synthetic resin pipe. The communication pipe 34 may be a rubber hose, a vinyl chloride pipe, or a corrosion-resistant metal pipe such as stainless steel.

  In the present embodiment, the float buoyancy adjustment drive means 14 includes a water supply / discharge pipe device 36 and a water supply / discharge drive device 38 for forcibly filling and discharging water into / from the float. The water supply / drainage pipe device 36 is a piping means for efficiently and effectively realizing water supply / drainage when water is forcedly supplied / drained into or out of the float. In the embodiment, two water supply / discharge pipe devices 36 are provided. The front wall bottom tube 40 piped by communicating end walls (front walls) 121EW near the bottom of the hollow case bodies 12A, 12B, and the rising tube 42 that is connected to the front wall bottom tube 40 and rises upward. And a water supply system including an upper surface wall side pipe 48 that rises upward in communication with the position near the upper end of the outer surface wall 121121GW of the hollow case body. Any of these water discharge systems or water supply systems may be FRP pipes, vinyl chloride pipes, stainless steel pipes, rubber hoses or the like.

  The position of communication of the front wall bottom tube 40 of the water discharge system with each hollow case body is set at the most separated position on the front wall, and the rising upper end position of the rising pipe 42 connected thereto is also substantially hollow. It is in a position near both ends of the body. As a result, as shown in FIG. 1, when a ship to be managed enters the intermediate gap between the two hollow case bodies of the catamaran shape, from the sea surface at a position that does not interfere with the ship's traveling path. The upper end portion of the rising pipe 42 can be disposed at the protruding position. A joint pipe 46 with a flow rate adjusting valve 44 is connected to the upper end portion of the rising pipe 42 so that a pipe extending from the pump side, which will be described later, can be easily attached and detached by an operation from inside the ship, for example. Yes.

  The upper wall wall side pipe 48 of the water supply system rises in the vertical direction at the same height position as the riser pipe 42, and a joint pipe 46 with the same flow rate adjusting valve 44 is connected to the distal end portion thereof. The upper ends of these rising pipes 42 and the face wall side pipes 48 or the upper ends of the joint pipes connected thereto are always projected from the water surface into the air, and the liquid amount adjustment in the float is performed through forced discharge and filling drive means. This is done only by the driving force. These upper surface wall side pipe 48 and riser pipe 42 form a connection part with a water supply pipe from the pump, and in the case of pump connection driving with another pipe, the opening functions as an air vent. In the present embodiment, two upper surface wall side pipes 48 and riser pipes 42 are provided, one on each side of the hull, a total of two, but in either case of supplying or discharging water to the float, It is possible to supply and discharge water only by connecting to one of them which is easy to use.

  The water supply / discharge drive device 38 supplies and discharges water (seawater) into the float and forcibly fills the float installed in a stable state on the water surface to reduce the float's buoyancy. A pump that drives the entire float down, and forcibly discharges water from the float to increase the float's buoyancy to drive the float up. For example, a pump driven via a power supply installed in a ship to be managed 50 is preferably used. The pump 50 sucks water in the float 12 and discharges it into the sea, and also pumps up seawater to fill the float 12 with seawater. A flexible pipe 52 for connection and a seawater-side flexible pipe 54 are connected in communication with the pump 50, and the flexible pipe 52 for connection is easily connected to either the rising pipe 42 or the joint pipe 46 at the tip of the upper surface wall side pipe 48. Detachable connection is possible. In FIG. 2, reference numeral 41 denotes a second front wall bottom-side pipe that connects the front wall bottom-side portions in communication with each other, and ensures a water amount balance in the hollow case bodies in the vicinity of the water supply / discharge pipe device. The upper end of the rising pipe 42 for supplying and discharging seawater may be open to the outside air. This is because buoyancy adjustment is performed by adjusting the amount of water in the float for forming a space portion that causes the size of the buoyancy, and complete airtightness in the case body is not required.

  Furthermore, in this embodiment, as shown in FIGS. 4 and 5, the float 12 is held at an arbitrary position on the offshore side from the quay WF by a rope 56 stretched between the land side and the underwater side. Since the float 12 fluctuates daily in response to tide levels that fluctuate due to tidal and wave movements, the vertical fluctuation is held at a fixed position on the sea while being absorbed by loose restraint by the ridge 56. Further, in the present embodiment, the float 12 is provided so as to be able to move between the installation position on the sea and the land by operating the rope 56 from the land WF side. In FIG. 5, the float 12 stretches a rope as a rope between an anchor post 58 installed on the quay WF and a discard anchor 60 thrown further offshore from the float installation position. The float can be moved in a locked state. For example, in the present embodiment, the pulley 62 is connected to the tip of the disposal anchor 60 with a length of about 1 m via a short rope, and the pulley 62 is circulated to form a loop between the anchor post 58 on the quay side. By configuring the loop part and the hull part together, the float position can be moved closer to the quay by moving the loop rope around the pulley. It can also be moved easily in the offshore direction. In this case, it is possible to allow movement between the quay side using the rope and the installation position while absorbing the vertical movement of the tide level at an offshore arbitrary position. In addition, the rope from the quay side is engaged through a spring opening / closing type hook 64 attached to the vicinity of the four corners of the upper surface wall 121UW of the float 12, and at that time, the rope forming the loop and the hull The float is moved by detachably engaging a part thereof with an appropriate method. At this time, it is basically possible to move the float supported by the buoyancy even with the locking force only of the weight of the rope. Fig. 7 shows storage on the water, mooring of the float by the rope at the time of management, and the hanging form. Prepare a mooring rope different from the above water locking rope, as shown in the figure The rope between the float and the anchor on the quay side is arranged to cross, and moored at a stable installation position so that the float does not move to the position where it fluctuated from side to side by restraint only in the biased direction when mooring the float by the rope You should be able to do it.

  Next, the operation of the present embodiment will be described. The simple marina apparatus 10 is installed at a maritime position separated by a required distance from the quay side, and the float 12 is buoyant as shown by the solid line in FIG. It keeps the state where the bottom BT of the ship is lifted to a position higher than the water surface. When the ship is used, for example, the rope 56 attached to the anchor post on the quay is loosened, the rope is operated so as to draw the float 12 to the shore side, and the ship is transferred from the land side to the ship. The floats being stored and managed are in a state where seawater is discharged to increase buoyancy and lift the ship bottom. Since it is difficult for the ship to leave the port, the seawater is supplied into the float 12. In supplying water, the flexible pipe 52 for connection of the pump 50 is connected to the water supply system of the water supply / discharge pipe device 36 to fill seawater with the seawater. Specifically, the free end side of the connecting flexible pipe 52 is connected to the joint pipe 46 at the upper end of the top wall side pipe 48 to open the valve 44 for communication, and the free end of the seawater side flexible pipe 54 is connected to the sea water. The pump 50 is driven in that state. Thus, since the buoyancy is adjusted by adjusting the amount of water in the float, the float can be driven up and down by buoyancy in a relatively short time. When the seawater is supplied to the float 12 to almost full tank, the amount of air in the float is reduced and the buoyancy is reduced. As shown by the chain line in FIG. 6, that is, the position of the WL line in FIG. It descends from the water surface to near the float portion 122, the contact plate 24 of the contact receiving mechanism 22 is separated from the bottom of the ship, and the hull is free from the float. In this state, the ship engine is started, the rope is detached from the opening of the hook 64 and removed, and in a state where the ship body is completely free, the ship is moved backward from the simple marina device 10 and sailed.

  When returning to the port and storing in the simple marina device, first, the hull is advanced in the middle of the post of the introduction index 32 as a guide, and stopped so that the mark of the support position matches the standing position of the post. In this case, a buffer member such as a rubber tire may be installed at the forward end position of the ship in the traveling direction. After the ship is stopped, the connecting flexible pipe 52 is connected to the joint pipe 46 of the rising pipe 42 of the water discharge system, and the pump 50 is driven to drain from the float 12, and the seawater passes through the seawater-side flexible pipe 54. Allow the sea to drain. As the amount of water in the float decreases and the amount of air increases, the buoyancy increases, and the contact receiving mechanism 22 lifts the bottom of the ship to a position higher than the water level to enter a managed storage state. In this state, the user will land, move the float from the shore to the offshore position to some extent using the rope, and store it in the water in that state. As described above, the upper end opening or the joint pipe 46 of each of the rising pipe 42 and the upper surface wall side pipe 48 of the water supply / drainage pipe device 36 may be closed or open, and management is extremely easy. No complicated processing is required. Therefore, the procedures for leaving and returning from the ship are extremely simple, and there is almost no need for maintenance. In addition, when the floating jetty is installed in the vicinity of the mooring place of the float, it may be used for boarding / exiting a ship.

  The simple marina apparatus and the marine vessel management method of the present invention described above are not limited to the configurations of the above-described embodiments alone, and can be arbitrarily modified without departing from the essence of the invention described in the claims. May be performed.

  The simple marina apparatus and the marine vessel management method of the present invention can be effectively used for water storage in coastal sea bays, lakes, ponds, rivers, and the like.
