Definitions
- the present invention relates to a planing sailing structure, of the pleasure motor boat type.
- the so-called outboard that is to say that the engine is entirely disposed at the rear of the hull, outside of the latter, generally above the transom, the propeller being driven by a vertical shaft and a bevel gear integral with this engine block, so that the steering and propulsion are ensured simultaneously by the engine block.
- This type of motor is reserved for powers of a few hundred watts up to powers of two to three hundred kilowatts.
- This category is renowned for its accessibility.
- the second category the so-called inboard that is to say that the engine is fixed in a housing reserved in the hull and this engine drives a shaft through the hull, shaft at the end of which is fixed the propeller.
- the motor is perfectly protected, protected from external aggressions, and the power
- REPLACEMENT SHEET installed is not limited.
- the engine is isolated, so noise is reduced and diesel engines can be installed, which is the most common case.
- the tree line requires a hull crossing which is always a weak point, and it induces vibrations in the hull during operation, against which it is necessary to fight, especially for applications to boating. All these boats which have inboard engines have hulls generating strong drag and the combination of faults leads to sluggish gear. To obtain acceptable speeds for pleasure craft, boats with these engines must be overpowered. In addition, the entire engine is bulky at the expense of the available hull volume.
- the third category called Z drive includes a motor integrated in the hull but the shaft line is replaced by a type outboard base, fixed on the hull.
- the motor has its drive shaft oriented towards the rear and this shaft cooperates directly with a set of two shafts, one vertical and the other horizontal carrying the propeller, the assembly being fitted with articulations and references d 'angle required.
- This base is adjustable, as for outboard motors, which ensures the directional movements of the boat.
- the hulls of existing pleasure boats are of many types, but there are essentially flat bottom hulls, y-shaped hulls and multihulls.
- Flat bottom hulls are reserved for limited applications, such as transportation, fishing or for boats with slow speeds. These are the least elaborate hulls.
- This type of flat-bottom hull is difficult to steer as soon as the speed increases and remains unusable as soon as the surface of the water is agitated, the slightest chop generating a comfort that is hardly acceptable.
- V-shaped hulls are the most common because they pass in choppy water and even in rough seas. In addition, they are fast.
- Multihulls are the fastest profiles but they are currently rather reserved for the competition. These multihulls are equipped with all types of engines, outboard, inboard or Z-drive, depending on the competition and the nature of the boats, in particular according to their lengths and their weights, therefore according to the power necessary to their propulsion. In this case, accessibility is not a real problem and silence, the absence of vibrations and odors, fuel savings, free and usable space of the cockpit or reliability in the long term are little studied and these criteria remain secondary.
- offshore type units are excluded because they require a very specific design, motorization and control.
- motorization and control we note that, if these multihulls are fast, they are also very stable and shallow draft, which is very popular for pleasure boating.
- flaps adjustable at any time in tilt are arranged at the rear and allow the angle of attack of the boat to be varied, depending on the speed and sea conditions, or depending on whether it is being planed out or planed.
- the subject of the present invention is a planing multi-pad sailing structure, with an engine attached in a hull housing but with a line of shaft external to the hull, fixed in direction, directional means of the rudder type, and a cockpit which can be converted on request.
- the present invention also relates to a multi-skid type boat hull designed to be motorized inboard or outboard, which combines the advantages of multihulls and monohulls by eliminating the drawbacks associated specifically with one or the other. other of these categories.
- the invention also proposes a particular embodiment of arrangement of a motorization for one of the preferred modes of multi-pad hull.
- the hull is very fast and very stable, it generates a very reduced drag, it easily crosses a formed sea, after planing its angle of attack is very stable and its wet surface very weak.
- the angle of inclination is nevertheless adjustable according to the desired applications and the motorization with which the hull is fitted.
- This engine can therefore be of the diesel type, and the fuel consumption is reduced on the one hand thanks to the use of efficient engines which are the engines. diesel and on the other hand due to the fineness of the hull and the little disturbance caused by the shaft and propeller line and by the displacement of the hull in the water.
- the very particular shaft line also contributes to fuel savings, high top speed, low disturbances, reliability of the assembly, and it avoids the installation of an inverter or a gearbox at speeds while offering a possibility of directional maneuver in reverse.
- This motorization can also drive a water jet propulsion turbine.
- Ribs are formed in the space between the pads and they extend until they reach the flattened middle part of the rear of the hull.
- the flattened rear surface is narrow and long and, moreover, completely disposed at the rear since it extends to the transom.
- the wet surfaces of the two front runners are of great length and of low finesse.
- the angle of attack is low in navigation, which does not reduce the wet surfaces either.
- the proof is that the ribs extend from the front to the flattened rear surface, on almost 2/3 of the length of the boat.
- the shell has a recess between the front pads and the flattened rear surface with a change in the angle of attack immediately upstream of the flattened rear surface which leads to a suction effect which sticks the hull on the water and in addition to increasing the drag, planing is made more difficult.
- British patent GB-A-1 273 692 which describes a y-shaped hull with two lateral skids at the front.
- This hull is essentially designed with a weight distribution such that the front pads actively participate in the recovery of the boat's weight and they have a large wet surface.
- the weight is therefore exerted in a privileged manner on the front pads.
- the pads are widely spaced but there is no longer a flat support surface at the rear.
- the outer edges are very raised and that the inner edges are softened. Also, the outer edge of the outer pad, during a turn, will lock and the centrifugal force will tend to overturn the boat in the event of too high a speed / turning radius ratio.
- patent application NL-A-83000343 describes an engine with a through shaft line, the assembly being mounted in a metal shell bottom. This bottom of the hull is then attached to an upper part of the hull by welding.
- Patent application O-A-91 12170 describes an assembly similar to that of the previous patent application because the engine is fixed on a hull part which is then welded to the rest of the hull.
- US patent US-A-1 850 770 is very interesting in its design because it allows the boat to ground despite the presence of a through shaft line.
- the cradle can thus pivot around this axis so that the part protruding under the hull, that is to say the wet part of the shaft and the propeller is retracted into the hull, thus eliminating any protrusion and authorizing support of the boat on the bottom of the hull.
- the object of the present invention is to overcome the drawbacks of the hulls of the prior art and for this purpose, the navigational structure of the planing type, comprising motor propulsion means, a hull designed to receive these propulsion means, and composed an upper convertible part located above the waterline and a lower part which includes wet surfaces, this lower part being divided into a front part and a rear part according to the direction of movement of the structure, the front part comprising two symmetrical runners, the rear part comprising a rear support zone comprising at least one runner is essentially characterized in that the front and rear runners are arranged on either side of the center of gravity of the structure along the longitudinal axis of this structure so that the rear support zone receives a load greater than that of the front runners and in that the angle of attack of the c o that compared to the surface of the water is positive whatever the speed of navigation.
- the fineness, after planing, equal to S / A, S being the largest transverse dimension of the wetted surface and to the area of this wetted surface, is greater for the rear support zone than for the front runners, especially the fineness of the rear surface is between 1 and 4.
- the depth of the skids is also increasing, relative to the waterline, from the front to the rear so, after planing, to come into contact with water only with the rear part of said skids, the area d intersection of these skates with water, that is to say the wet surface, having a spearhead shape.
- the rear support zone comprises a single central shoe or two rear shoes arranged on either side and upstream of the engine.
- the transverse distance which separates the front runners is greater than the distance separating the rear runners or the wings of the central runner so that the inner vortexes created by the inner edges of the front runners go towards the outer edges of the said runners rear and central skids.
- the distance d which separates two transverse lines a and b passing respectively through the centers of gravity of the front runners and through the center of gravity of the rear runners or of the central runner is adapted as a function of the inertia the structure and the height of the wave or chop intended for the navigation conditions usually encountered.
- the surface connecting the front runners and extending to the rear support zone is substantially flat and has a positive angle of attack relative to the surface of the water.
- the wetted surface when stationary, is substantially equal to the projected surface of the hull on the surface of the water.
- the hull has a rear width greater than the front width, so that the distance between the rear runners is greater than the distance between the front runners, which increases stability, including in the flight position and optionally allows double motorization.
- the invention also relates to a particular method of mounting and arrangement of an onboard engine.

- FIG. 10 a side elevational view of an alternative embodiment of Figure 7, Figures 11 and 12, sectional views along lines 11-11 and 12-12 of Figure 10, and - Figures 13, 14 , 15 and 16, identical views to Figures 6, 7, 8 but for an alternative embodiment, of the competition type.
- FIG. 1 there is shown a navigating structure according to the invention which comprises a front part 10 and a rear part 12 arranged along the longitudinal axis 14 of the structure.
- FIG. 2 and 3 will further understand and better visualize the profile of the hull 16 of this sailing structure.
- the front part 10 of the shell 16 comprises two pads
- each of these pads is interrupted at the junction of the front and rear parts, that is to say substantially in the middle of the boat.
- the two pads end in a transverse plane 24 and 26 inclined on the order of 50 °.
- the central bridge 22 has the sole role, the connection of the two pads together, the assembly being monolithic, molded.
- the monolithic hull thus produced can support a cockpit 28 in the upper part.
- the hull is completed by a front deck 30 and a windshield 32, of known type and corresponding to certain applications in pleasure boating, such an arrangement with closed cockpit can of course be replaced on certain models by a sit-stand console, without bridging.
- the rear part 12 includes a central support zone
- This central support zone projects in line with the longitudinal axis 14 with respect to the lateral edges 36 and 38 which are raised towards the outside, as can be seen in FIG. 3.
- the shell also comprises a housing 40 disposed at the rear of the central support zone, which extends in height up to the level of the cockpit.
- the cross line passing through the center of gravity is called spear-shaped hatched surfaces which represent the intersection of each of the skids with the surface of the water, therefore the wet surface, when the hull is planed and b the transverse line passing through the center of gravity of the central support zone 34.
- the distance d which separates these two transverse lines is short, but it can be adapted according to the navigation conditions most often encountered. The distance is essentially determined by the fact that the center of gravity of the structure must be for the most part, of the order of 80%, taken up by the central rear support surface.
- the fineness is the ratio of the square of the rear base S of the wet area, that is to say the largest transverse dimension, on the surface A of this wet area.
- the vortices 42 created by the inner faces of each of the pads abut on the sides of the central support zone, the surface of which intersects with the water is substantially truncated there, the point of which is oriented towards the before.
- Another advantage of this hull is the good heading behavior resulting from the "rails" that constitute the two hulls and the projecting part of the central support zone.
- a double-shell construction with floating material inside gives the sailing structure unsinkability qualities, in addition to soundproofing qualities.
- Line I corresponds to the maximum admissible load
- line II corresponds to the empty waterline
- line III to the planing
- line VI to the hull bottom plane.
- the surface of the navigating structure, projected onto the surface of the water is substantially identical to that of the wet surface, at a standstill, that is to say the surface included inside the line of buoyancy I.
- Figure 3 has the same reference numerals for the visible common areas. It helps to better understand the shape of the hull.
- FIG. 4 the motorization of the hull of the sailing structure according to the invention is shown, and more particularly the mounting of the motor with a cradle in the housing 40 of the hull.
- the cradle 44 has a substantially parallelepiped shape with its upper face 46, open.
- This cradle includes legs 48 with silent blocks, designed to receive an engine 50, shown in broken lines in this figure 4 for simplification and clarity of the figure.
- the cradle 44 includes an edge 52 forming an outer wing over its entire periphery, this edge being provided to cooperate with a seal 54 and screws 56 for fixing on the shell itself.
- the seal 54 is preferably located above the waterline whatever the speed of the boat.
- the bottom 58 of the cradle is slightly inclined and raised towards the rear.
- This bottom further comprises a shaft passage 60, sealed.
- This passage is a tube 61 secured to a support 63 itself fixed on the cradle, making it possible to carry out the sealing around the rotating shaft.
- the tube 61 is fixed by one of its ends and it comprises, at its other end, an inner ring 65, arranged around the rotary shaft, which ensures the seal.
- the tube can therefore move slightly and in particular absorb vibrations without the support 63 undergoing significant efforts.
- the cradle 44 further comprises a shaft support 62 comprising a plate 64 attached to the cradle 44. This plate 64 supports a tab 66 articulated by silent blocks 68.
- This tab 66 comprises at its free end a ring
- the propeller shaft 78 passes through the ring 70 and its free end 80 is equipped with a propeller 82 of the cavitating type.
- the shaft support 62 also includes a steering member 84 composed of an actual rudder 86, of the annular type, disposed at the immediate outer periphery of the propeller.
- This ring varies from front to rear increasing and the width also varies decreasing from L to 1 from the upper part of the ring to the lower part, in order to avoid disturbing the flows and decrease the drag.
- This ring is connected to a drive shaft 88, fixed at its upper part, itself supported by the plate 64, secured to the cradle 44 by means of a support arm 89 also secured to the lug 66 in which the shaft 78 rotates. propeller 82.
- This operating shaft 88 can therefore rotate on a given angular sector around the axis 90, preventing the annular part from coming into contact with the propeller.
- This ring is also equipped with a water intake 92, with an opening oriented in the direction opposite to the direction of rotation of the propeller.
- the ring is also made of a material having sufficient mechanical strength to support most of the weight of the structure when it is dry because the lower part of the ring is below the line IV of the hull bottom.
- control linkage 94 connecting the rudder shaft to the cockpit.
- the cradle 44 further comprises a feedback device 96 which comprises a plate 98 fixed to the end of an articulated arm 100 relative to the plate 64 of the shaft support.
- This arm is integral with the operating means 102, in this case a linkage, which allows up and down movement of the plate 98 between a high retracted position, shown in solid lines, and a low working position, shown in broken lines. .
- the length of the arm 100 is such that the plate in the working position is placed behind the annular rudder while allowing the rotations of this rudder, position shown schematically in broken lines.
- this plate comprises two symmetrical cavities with respect to a vertical plane passing through the center of the propeller.
- the engine 50 it is in the intended embodiment of a diesel engine, 4 cylinders, derived from the automobile and marinized. The choice depends on the size and the power required.
- the motor 50 is oriented so that the power shaft 104 is positioned forward, this in known manner.
- a pinion 106 has been mounted, provided for cooperate with a flat and toothed belt 108 which itself cooperates with a transfer case 110 secured to the motor 50.
- This transfer case comprises a pinion 112 designed to receive the notched flat belt, this pinion 112 being mounted on a shaft 114, mounted to rotate freely in a bearing 116.
- the free end 114 comprises a half-shaft 118 of cardan, linked to the second half-shaft 120 of this cardan, itself integral with the end of the propeller shaft 78, located inside the cradle.
- a removable plate 122 having a section substantially L-shaped with stiffeners 124.
- the vertical branch 126 of the L is fixed by screws 128 on the wall of the housing 40 and the horizontal branch 130 of the
- the user in the cockpit, has access to an acceleration / deceleration control, a forward / reverse selector, as well as a steering wheel control.
- the start-up using a battery and a starter associated with the engine is carried out by the user without any particular maneuver and from the start-up, the fact that the engine is in a closed enclosure on the outside and simply open towards the surface of the water, gives all of the qualities of certain acoustic damping.
- the vibrations are doubly damped by the silent blocks of the lugs 48 supporting the engine and by the cradle support means 44 thanks to the wings 52 of the cradle and to the seal 54 for sealing and acoustic damping.
- the drive shaft 104 driving the belt 108 causes the propeller shaft 78 to rotate.
- the sealed passage 60 allows the shaft 78 to rotate, avoiding any penetration of water into the cradle 44.
- the shaft 78 rotates in the ring 70 lubricated by water and rotates the propeller 82 fixed at its end.
- the hull At low speed, the hull is not planed and the entire propeller and rudder is in the water.
- the removable plate 122 which is an integral part of the central support zone, contributes to supporting the hull and plays a role in the incidence of the hull relative to the surface of the water.
- the propeller is then half in water, half in air and operates in cavitating mode, the mode for which it was designed.
- the rudder is always active by the lower half-ring whose reduced width also limits the drag.
- the tab 66 equipped with the ring 70 oscillates in this case relative to the plate 64 around the axis 74 thanks to the silent block 68 and the mounting of a flexible shaft.
- the ring of the opening 60 formed in the cradle 44 provides sealing, including during the translational movements of the shaft relative to the cradle.
- the half-cardans 118 and 120 compensate for the misalignments so that the pinions 106 and 112 remain perfectly aligned and can cooperate at best with the toothed belt 108.
- This is positioned behind the rudder and receives the entire flow of water pushed by the propeller.
- the rudder makes it possible to orient this flow towards one or the other of the cavities of this plate, which leads to reverse gear on the corresponding side.
- the propeller always turns in the same direction, including in reverse, as has just been explained.
- Such a sailing structure therefore has many advantages and in particular the combination of an inboard engine with the accessibility qualities of an outboard engine.
- a water intake such as the water intake 92 formed inside the ring 86 constituting the rudder 84 with its orientation in the opposite direction to that of the rotation of the propeller allows circulation under pressure, the propeller behaving like the blade of a pump.
- the gases are exhausted in a known manner with the discharge of the cooling water from the secondary circuit into the water, this transverse to the axis of movement of the boat.
- the shell does not undergo any drilling, no modification of fixing.
- the shell is preferably made of a sandwich material and foam is injected between the outer layers so as to improve the sound insulation without weighing down the structure.
- foam is injected between the outer layers so as to improve the sound insulation without weighing down the structure.
- FIGS. 6 to 11 an alternative embodiment is shown which is more particularly applicable to outboard motors, the motor shown bearing the reference 250.
- This engine is not described in detail because it is of a known type, sold commercially and arranged according to the manufacturer's instructions, without modification for adaptation to the hull which will be described.
- the aft support zone 234 comprises two separate pads 234 T and 234 B, starboard and port, in the immediate vicinity of the transom so that the center of gravity is, after planing, in line with this aft support zone, similar to application to the inboard engine.
- the water flow can circulate without disturbance, which leads to a very good supply of water to the propeller of the outboard motor, greatly limiting the effect of cavitation, including when cornering.
- the vortex effect generated by the front skids ensures good heading stability by stabilizing the hull laterally, as in the inboard version.
- the central part does not have any marked change in slope, so that the vacuum effect is eliminated at the start of planing and immediately after, the underside of the middle part of the hull is above the surface of the water with free air circulation.
- Roll is also controlled by the spacing of the front pads but especially by that of the rear pads which should be by their lateral ends at least as far apart as the front pads, or even with a greater gap.
- This constraint is difficult to achieve on hulls intended for pleasure but presents all its interest for competition hulls as indicated later in the description.
- the arrangement according to the invention leads to narrow wetted surfaces longitudinally, with a spearhead shape, which decreases the drag by increasing the smoothness S 2 / A, and therefore increases the performance of the sailing structure.
- fins are provided. front side 202 and rear 204, in the lateral extension of the front and rear support pads. Such fins complement the qualities of the sailing structure.
- Figures 13 to 16 correspond to an alternative embodiment of the competition type.
- the hull also includes two lateral support pads with a spacing greater than the front pads, this to the detriment of habitability which is reduced but which is not sought in this type of application in the sports field.
- the upper spacing of the rear runners also gives a delta shape to the hull so that its behavior is excellent even when the hull flies over water after a wave pass for example.
- the hull has wing profiles with a central channel.
- All the sailing structures described are preferably made of composite materials in order to obtain the particular shapes sought, for better sound insulation with low propagation of vibrations.
