Description

Sailboat.

This invention relates to a sailboat and a motorboat or vessel equipped with 5. sails. We will collectively refer to boat types as sailboats.

One source of power for the sailboat is the wind, which is utilized mainly through the sail, wing or floating sail systems associated with the boat. In addition to the sails, the sailboat may be equipped with an engine for special situations, such as entering and leaving the port or 10. in adverse wind conditions. The maximum structural speed of a sailboat is influenced by, for example: the efficiency of the sail arrangements, the wind resistance of the sailboat, and in particular water resistance such as friction or wave resistance, and the overall capability of the boat to exploit wind conditions varying in direction and intensity and to convert wind energy into forward and offshore motion in a safe, economical and practical manner.

Known Sailboats can be roughly divided into single hull or multi hull hulls. Multi-hulled boats are basically made up of multiple hulls connected to one another by supernatural deck or support structures. It is possible to equip boat hulls with 20. carrying wings or to stabilize outboard structures.

Regardless of the sailboat hull type, modern high-powered sails can be roughly divided into front sails (fox, genus, genaaker, ball sail, etc.), big sails, and less common kite sails that are outside of this review. The sails are generally of the 25th triangular shape, with three angles connected by three edges, or movements, which in the future will be referred to as front and rear and up or down movement with respect to the direction of the boat.

The foremost rails are generally attached from the top of the forehead to the top of the mast, from the lower forehead to the center of the boat directly or indirectly through, for example, the bow and the third angle for sail stands to sail stands 30 located or operating on either side of the boat centerline. The ball sail is secured at its upper corner to the upper and lower corners of the mast by separate leg systems, which are located on each side of the center line of the boat, possibly via an auxiliary boom attached to the mast.

The main sails are generally attached from their forward movement to a fixed mast or pivoting 3 5. wing wing mast or mast portion and to a lower or lower corner boom with one end attached to the mast and the other end to a transom or torso system extending over the center line of the boat.

The optimization of the known solutions described above with respect to the speed of the sailboat 40. raises practical problems and requires skilled crew and may present unexpected incidents in extreme situations. Trimming known sail systems is extremely difficult and difficult because trimming the front and main sails interact with each other through mast deflection. 45. The poor ability of known single hull boats to convert wind energy into the forward speed of the boat results in the boat not being sufficiently sturdy as such to carry the required sailboats, but requires keel or moving counterweights and even crew shifting on small boats. Deep heavy keel limits the use of the boat in shallow water and requires special towers for transport on land, etc. Multi-hull boats generally have good ability to convert wind energy into boat running motion, but boats are wide in length and 50. require similar features from boat mooring, haulage and bulkhead. The maneuverability of multi-hull boats, especially in creative turns, is poor due to the upwind, due to a number of factors including: high wind resistance and turning resistance caused by long narrow boat hulls.

The sailboat of the invention is intended to substantially eliminate or reduce the above drawbacks and to enhance safety, usability and overall functionality. Wind energy is a 5. ecologically sustainable form of energy and the solution of the invention is intended to bring the nature of sailing closer to the nature of motor boating as claimed. With its new features, the sailboat of the present invention is a real energy-saving purchase option for a powerboat and is aimed at new user groups. The sailboat according to the invention moves quickly on sails and turns easily also on the creatures because the water resistors 10 are small and the united stern due to its width and shape moves easily sideways. The sailboat of the invention is a very stable single hull boat under all wind conditions, based on its bottom and bow shape. The boat's hull is exceptionally spacious and load-bearing, especially for the stern of the boat, so that even a small boat can accommodate a safe, functional seating, cabin or inboard engine.

15.

The claimed boat hull provided with the claimed sail solutions is as easy to use as the trim of the sails is limited to pedestal operation while the force exerted by the wind on a single sail is substantially less than the traditional undivided force. The sail arrangement 20 according to the invention transmits to the hull of the boat a great forward force in relation to the heeling torque, i.e. the efficiency of the sail in the forward direction is extremely good. The potential adverse effect of the mast on the air flows in connection with the sails has been completely eliminated by the sail arrangement according to the invention.

25. The claims clarify what a sailboat invention is.

Piir. 6 shows another embodiment of a sailing boat according to the claims, depicted directly from above.

Piir. 7 shows a separate application according to the claims, wherein all the keel is replaced by a design 38 of the outer sides of the boat hull which acts with the base 4 as a guide keel.

In the following, a few embodiments of the claims will be described, in general terms, with reference to the accompanying drawings and part numbers, without limiting the broader or divergent use of the claims.

Drawing Drawings In the embodiments 1,2, 3 and 4, the sailboat boat part consists of one boat hull 1 provided with a single stern part 2 and two water-cutting bow 3 interconnected by a tunnel-shaped bottom 50 4 above the waterline 10 or the water surface 24 which descends towards the stern 2 Slightly below the water surface 24 ending at stern 2. Known bow solutions 3 strongly resist boat tilt 5. based on the bow's distributed carrying capacity and the high straightening torque due to the "windward" distance of the bow 3 due to the wind on the 'bone guard' side, the bow 3 acts as a counterweight.

Due to the uniform stern 2 and its bottom shape, the stern of the boat moves gently sideways, minimizing the braking effect of the rudder 19 during the turn. In the 10th embodiment shown, the wooden boat has a single deck 21, a seating pan 18 and one rudder 19.

In the drawings, FIG. 1, 2, 3 illustrates a tubular boat application equipped with two pivoting keel 12a disposed on either side of the tunnel-shaped base area 4 or 11.

15. In the drawings, FIG. In the embodiment shown in Figure 4, the sailboat is equipped with two hoisting ropes 12b.

In the drawings, FIG. In the embodiments shown in Figures 1, 2, 3 and 4, the sailboat is provided with a mast 16, one of the claims, a pair of sailboats 5, consisting of two double sailboats 6, replacing the traditional big sail 36 shown schematically in FIG. 5. The twin beams 6 are wholly or partially disposed on opposite sides of the boat centerline 20 in a forward motion via lower anchors 7. The upper parts 8 of the forward movements of the twin tubes 6 are attached directly to the upper part of the mast or via the twin tubes 6, for example, lifting systems, winding systems, forks or straps 15.

25. The sail pair 5 according to the invention, where the pair sails 6 are inclined inwardly towards the mast, preferably windwardly inclined forceultants, minimizing the inclination, while dividing the sail area into two pair of tubes 6 lowers the sails and mast 16 without loss of power the tilt effect of the wind is thus further reduced.

30.

Drawing border. In the embodiment shown in Fig. 1, the front flaps 7-8 of the pair sails 6 are secured to the side rims 15 of the mast 16, which at the same time support the mast 16 laterally and obliquely backwards. In the embodiment shown, the front sail 22 is a traditional self-propelled front sail, that is, a fork 22 with its equipment. The front sail 22 is secured by its forward movement to the upper part of the mast 16 and to the center 35 of the cover 21, and at its rear angle to the base rack 23 located on the deck 21 in front of the mast 16. The adjustment systems, i.e. the leg systems or the levellers 14, which influence the tension, shape, position and position of the sails angle 9 of the pair sails 6 are raised from the cover 21 by means of a structure 25, i.e. '' Targa fishing arch ".

40. In the drawing, FIG. In the embodiment shown, the pair sails 6 of the sailboat are provided with booms 17, to which the bottom locks 7-9 of the pair sails can be secured throughout or as illustrated in points 7 and 9. The front end of the boom 17 is pivotally secured to the boat deck 21.

Drawing border. 3 shows another embodiment as a pair of sails 6, in which the pair sails 6 are provided with fixed or detachable stiffeners, i.e. bars 37, in the sail. These allow the rear movement 26 of the sail, which in the embodiment shown is curved, to remain in the desired position.

Drawing border. 5 shows a drawing of the drawings. 1 to FIG. 4, wherein the air currents 33 and 34 caused by wind 32 in connection with the twin sail 6 of the present invention 50 are compared with the air currents of the big sail 36 attached to the mast 16. As we see with the traditional big sail 36, behind the mast 16 there is a creative flow of backflow 35 which diminishes the desired vacuum and power behind the sail 36 while the sail 5 according to the invention.

The currents 33 and 34 remain laminar and thus optimal. The arm or rim 15 may be replaced by a sail winding system 40.

Drawing border. 6 shows a top view application according to the claims, which differs from the preceding embodiments, wherein the sail boat is provided with a covered seating pan 18 or a cabin 30 with a roof opening with a hatch 31 and the seating pan 18 being exposed. The sailboat according to the embodiment is provided with two rudders 28, which are controlled by the steering wheel 29. The twin sails 6 are secured to arms 15 separate from their forward movements 7-8, which are secured to the upper part 8 of the mast 16 and lower part 7 opposite the center line 20. In the embodiment shown, the central portion of the mast 16 is supported by a cover 21 with separate straps 27. The pedestal systems or the levan systems 14 are located within the roof of the complete structure or cabin 30.

15.

Drawing border. 7 shows a different embodiment of the claims according to the claims as compared to the previous applications, in the middle section A-A of the hull, in which the flanks 38 of the sail hull are replaced by e.g. the known keel variants 12a, 12b described above. An important detail of the invention in terms of operating karmic is the relatively underwater side vertical region a of the boat 20. which resists lateral force of the wind causing the boat to tilt and the vertical underwater area a to grow b at water level 37.

The disclosed embodiments represent a few examples of the claimed embodiments, without limiting the broader or divergent use of the invention as claimed. As an example, the number of pairs of sails 5 may be varied, such as the combination and number of one or more known front sails, special sails or large sails operating with twin sails 6.

30. The disclosed keel applications are examples which do not exclude known solutions, such as one or more solid keel which may be provided with additional weights or that the presented keel variants are provided with weights. The embodiments disclosed include all self-evident neces- sary equipment associated with twin sails 6 as well as known sail systems, such as ropes, lifts, winches, claws, folding blocks, etc.
