Definitions

  • the invention relates to a sailboat according to the preamble of claim 1.
  • the invention has for its object to be the sailboat of the generic type elimination of the disadvantages described so that it is designed to be capsize-proof with easy maneuverability and can not only be built with a smaller width than usual, but also allows higher sailing speeds without the risk of undercutting.
  • a double hull sailing boat in the form of a catamaran is already known (FR-OS 25 14 718), the floating body of which consists of two hulls which are connected at a distance from one another.
  • FR-OS 25 14 718 the floating body of which consists of two hulls which are connected at a distance from one another.
  • these each have the classic keel shape, i.e. the height of the hulls increases steadily from the front to the aft, the hull cross section always being more or less knife-shaped and, in contrast to the invention, does not have a spoon shape enlarging the support surface on the bow side.
  • the hulls have a special shape and a special cross section, in such a way that each hull has a bead or drop shape on the bow side or in its front region, which merges aft into a wedge or cutting shape .
  • the lateral plan formed by the surface of the longitudinal section of the hulls below the immersion plane is designed in such a way that the lateral center of gravity is shifted aft behind the middle of the ship.
  • the mast holder is arranged in the rear half of the ship. To compensate for this is the operator station moved forward for the sailboat in such a way that it is formed between the outer hulls and arranged in front of the mast mount.
  • the sailboat not only as a double hull, but also with several, for example three hulls.
  • the special hull shape provided in accordance with the invention in connection with the aforementioned design thus makes it possible to build a multihull boat with considerably smaller width dimensions than usual. While, for example, in a conventional catamaran the width corresponds to approximately half the length of the boat, for example in the dimensions of 6 m length and 3 m width, the double-hull boat according to the invention can be designed with a considerably smaller width.
  • the width of the boat is only 1.50 m.
  • the transition area between the drop or bulge shape of the hull and its cutting shape is preferably in the front half of the ship, so that on the one hand each hull is wide and compact in its front area and thus generates a relatively large buoyancy, but on the other hand in the rest, especially in rear section shaped is.
  • This shape of the cutting edge of the fuselage acts in such a way that a drift beyond the usual extent is prevented, so that this cutting shape looks like a keel or sword in this respect, but without, as mentioned, a keel or sword being provided.
  • the hulls of the sailboat are not designed to have a constant height, but if the height of the hulls increases from front to aft, in such a way that the distance between the upper and lower boundary edge of the hulls increases continuously towards the aft.
  • this results in a sufficiently large contact surface in the front area of the fuselages, caused by the wide, compact hull shape, with the resulting great buoyancy, and on the other hand, an enlarged cutting-shaped immersion area is achieved in the rear fuselage area due to the cutting edge shape provided there, which is a substantial ensures improved maneuverability.
  • This increased maneuverability of the sailboat according to the invention is further improved in that the hulls on the stern side are extended beyond their vertical boundary by a cutting surface which ends in a triangular, pointed shape.
  • the rudder blade can be articulated on this cutting surface of the fuselages, this being done in such a way that the respective rudder blade runs overall at the same height as the hull in question. This advantageously enables the sailboat according to the invention to be used on any beach or to sail in shallow waters without it being necessary to bring up the rudder blade, which otherwise projects downward.
  • the operating station is expediently designed such that the front part of the platform rigidly connecting the hulls forms the operating station and is in particular shaped as a seat.
  • alternative operating positions near the rear area of the main control station, for example on either side of the mast mount, in order to be able to provide the necessary weight balance in the case of high winds by shifting the body accordingly, or to have the possibility to be able to carry two or even three people on the sailboat according to the invention.
  • the mast receptacle arranged in the rear half of the ship is so high that its top runs above the head height of the person in the operating position. This makes it possible to even rotate through 360 0 the mast including the hereby fixed to the sail via an angular position of 90 ° addition, without the person located on the operator position is compromised. This increases the capsizing safety of the sailboat considerably, since if necessary the sail can pull out in a corresponding manner.
  • the mast receiving bore of the mast receptacle is arranged at a point on the rear half of the ship which is at a distance of approximately 40% to 30% of the length of the ship from the rear hull or boat end.
  • the mast receptacle can in particular be approximately anvil-shaped with an arm projecting aft, the arm of the mast receptacle or the mast tree attached to the mast extending approximately to the end of the boat.
  • the sailboat designed in accordance with the invention not only achieves an increased sailing speed with improved capsizing safety and greater maneuverability, but also the width dimensions can be reduced at the same time, which increases the handiness of the boat, in particular during transport.
  • the intended special hull shape in connection with the mast shifted to the rear and the control station located in the front half of the ship between the hulls provides a further increased stability with improved sailing properties, without it being necessary as before to prevent an unacceptably high drift of a sword or to provide such a rudder blade which projects downward over the lower boundary plane of the hulls.
  • the rudder blade can advantageously be arranged at the same height range as the hull in question, so that sailing in shallow waters and driving onto any beach is possible without the need to raise the rudder blade or pull up the sword is.
  • the front provides Fuselage area due to the bead-like or drop-shaped design for increased buoyancy, while, in contrast, the cutting shape of the respective fuselage provided for a corresponding transition area prevents inadmissible drift in the remaining fuselage area and at the same time increases maneuverability.
  • the sailing boat shown has two hulls which are arranged in parallel at a distance from one another and are rigidly connected by a platform 2.
  • a mast mount 3 is attached in the longitudinal median plane of the ship, which is used for the rotatable mounting a mast 6 provided with a mainsail 4 and a foresail 5 is used.
  • the two hulls 1 of the boat have a special shape and cross-sectional configuration, in such a way that they have a bead or drop shape 27 in the front region, which transitions aft into a wedge or cutting shape 28.
  • the transition region 13 between these two special hull shapes 27, 28 lies in the front half of the ship, which is delimited by the transverse center line 30 indicated in FIGS. 1, 2 and 4. If desired, the aforementioned transition area 13 can of course also be arranged in the rear half of the ship.
  • the height of the hulls 1 increases from the front to the rear in such a way that, seen in a side view, the distance between the lower boundary edge 11 of the hulls 1 and the upper boundary edge 14 increases astern and that the upper fuselage edge 14 rises aft with the lower fuselage edge 11 running parallel to the immersion plane 38.
  • the two fuselages 1 are extended beyond their imaginary vertical boundary line 15 at the rear, the extension likewise having the shape of a cutting surface 16.
  • This cutting surface 16 ends in a triangular shape at the top.
  • a rudder blade 9 is articulated, which has the shape shown in FIGS. 1 and 2 and with its lower edge 12 runs at the height of the lower fuselage boundary edge 11 such that the rudder blade 9 as a whole is in the horizontal alignment line of the longitudinal median plane of the fuselage 1 in question.
  • the sailing boat shown is designed without a sword and without a keel and has the described special arrangement of the respective rudder blade 9, the hulls 1 with their lower longitudinal edge 11 form the deepest limiting plane of the boat.
  • the two hulls 1 of the boat are arranged so close together that the boat width is less than half the length of the boat.
  • the lateral plan formed by the surface of the longitudinal section of the hulls 1 below the immersion plane is designed in such a way that the lateral center of gravity as a whole is shifted aft behind the middle of the ship.
  • the mast receptacle 3 is arranged in the rear half of the ship, in the illustrated embodiment a bore 19 receiving the mast 6 in the mast receptacle 3 is located at a point on the rear half of the ship delimited by the transverse center line 30, which is a distance of approximately 40% of the length of the ship to the rear end of the ship 15 (imaginary vertical rear hull boundary edge 15).
  • the sailing boat shown has a control station 10, which is shifted forward to compensate for the mast 6, which is shifted far aft, between the two hulls 1 in front of the mast receptacle 3.
  • the front part of the platform 2 is approximately triangular Seat designed with a corresponding border 31.
  • the arrangement is such that the horizontally extending upper side 18 of the mast receptacle 3 extends at a height above the head height of the person located on the operating position 10.
  • the mast receptacle 3 has approximately the shape of an anvil with a foot 21 and one which projects freely aft thereof Arm 20, which extends to about the height of the boat end 15 in the illustrated embodiment.
  • the foot 21 of the mast receptacle 3 has a vertical bore 19 which supports the mast 6 in such a way that it can be freely rotated through 360 °.
  • the bore 19 is lined with a sleeve 22 which is closed at its upper end with a bush 23 and at its lower end with an abutment 24. Both the bushing 23 and the abutment 24 are made of highly slidable plastic, so that the mast 6 can be rotated freely and easily.
  • a mast mandrel 25 is provided which passes through a through hole 32 in the platform 2 and protrudes downwards.
  • the mast mandrel 25 is provided with a split pin 26 so that the mast 6 is reliably secured against unintentional pulling out of the bore 19 of the mast receptacle 3.
  • the mast 6 is arranged at an angle of 90 ° to the horizontally extending upper side 18 of the arm 20 and is firmly connected at its lower end to a mast boom 7 and at its upper end to an erector 8.
  • the mainsail 4 is attached on the one hand to the mast 6 and on the other hand at least at two further points 33, 34 on the mast boom 7 and on the erector 8.
  • the foresail 5 is attached, which has the shape of a narrow, elongated rectangle in the manner shown and is designed as a wind trimmer. This wind trimmer 5 is connected at both ends via the points 35, 36 to the mast boom 7 or the erector 8 and attached to the mast 6 via at least three further points 29.
  • mast boom 7 and top 18 of the arm 20 of the mast holder 3rd run strictly parallel to each other, the entire, formed from mast 6, boom 7, erector 8, mainsail 4 and foresail 5, relatively rigid unit can be rotated freely, not only over an angle of 90 °, but a total of 360 ° .
  • This gives an extraordinarily high capsizing safety and also makes the arrangement of shrouds, backstays and forestay superfluous.
  • the rotating plane of the mast boom 7 is above the head height of the person located on the operator position 10 that this operator is not endangered.
  • side-by-side service stations 17 are formed next to the operator station 10, which are located on both sides of the mast holder 3 and can serve to accommodate other people or the person on the main operator station 10 if there is a shift in weight or strong winds balance should be required.
  • the sailboat shown has a maneuverability that is significantly improved compared to a conventional catamaran, even even compared to a conventional monohull sailboat, which is based not only on the special design of the hull shape or the hull cross-section, but not least on it that no sword or rudder blade surface is provided which projects downward beyond the boundary plane formed by the lower longitudinal edge 11 of the hulls 1.
  • the sailing boat shown has a differently positioned immersion level depending on the prevailing wind strength.
  • FIG. 2 For the sake of example only, two different immersion planes 37, 38 are indicated in FIG. 2, the immersion plane 38, for example, with wind force 1 and the immersion plane 37, for example with wind force 3 to 4.
