Definitions

  • the invention relates to a sailboat with a predominantly closed boat hull, a mast boom supported in the boat hull and a rudder device.
  • a sailboat in the sense of the present invention is to be understood as a one-masted, possibly multi-masted, equipped with a sail and propelled by wind power, whose hull is made of wood, glass fiber reinforced plastic or in a composite construction, the design as a keelboat or flat-bottomed with a sword can be provided to reduce drift.
  • the invention has for its object to provide a novel sailboat of the aforementioned design, which has a hull with both high strength, high positional stability and automatic straightenability after the kentem to achieve great seaworthiness and also with low flow resistance and optimal sailing properties, especially when Crosses against the wind should be provided.
  • this object is achieved for a more general embodiment in that the shape of the boat hull is determined by cross sections which form upright, in particular equilateral triangles with convexly curved sides and continuously up to the bow and stern Reduce approximately to the point size so that the three edge lines containing the corners of the triangles meet there and a largely symmetrical body is formed around its main axes, in particular an ellipsoid with particularly favorable strength properties.
  • a total of at least two or four downward and outward-inclined rudders are provided on both sides of the fuselage in front of and behind the transverse center thereof, which have adjustable shafts with rudder-like widenings which are guided approximately vertically through the respective side wall, which can be filled with ballast and at the same time are designed as feet, in order to be able to land the boat near the shore or in the event of tidal changes, and that the mast rotatably held in a receptacle arranged in the middle of the hull forms part of a profile sail, which is a plan view Has wing profile, approximately in the longitudinal center of the mast and at the front end of a laterally adjustable flap are provided as an adjustable inflow profile.
  • the fuselage has a shape approximating an ellipse, but the ends, slightly different from an ellipse, are extended by a bow tip attached to the front at the top.
  • the elliptical shape gives the hull additional rigidity, but a center piece can be used to extend the hull.
  • the hull is made of laminated mahogany wood, the wood laminates being glued with epoxy resin and glued to a prefabricated group of ring-like frames.
  • Another peculiarity of the sailboat according to the invention consists in at least two pairs of oars protruding downwards, which can be adjusted to compensate for the drift and the heel and at the same time serve to stabilize the hull like a keel by ballast.
  • the rudders with rudder-like extensions can be adjusted depending on the wind direction and speed about their longitudinal axes and act as feet, e.g. B. if the ship is sitting on the ground when the tide changes. Because they can be adjusted around their longitudinal shafts, they also enable changes in direction and, of course, the application of course holding forces in conjunction with the forces acting on the sail.
  • the sailboat of the invention embodies the profile sail, the mast from above in a z. B. is provided centrally in the fuselage receptacle.
  • the mast preferably consists of a triangular tube, although other profiles can also be used.
  • the mast can be rotated by the motor drive.
  • the profile sail which contains the mast as a supporting part, has a wing profile in plan view, which has a swiveling flap at the front end in order to be able to cross against the wind with the best efficiency.
  • the fuselage on the bow can be extended so far by an attachment that the top thereof is approximately flat and flush with the upper side edges of the fuselage, while the keel edge of the fuselage is continuously continued up to the tip of the bow.
  • Dome-shaped pulpits made of transparent material can be provided on the bow and in the area of the stern in order to seal off the rooms behind them.
  • boom structures consisting of frame structures are guided vertically displaceably, an uppermost sail boom of the top boom being able to be pulled up to an uppermost position on the mast via one or more cable pulls and deflection rollers, while those arranged below it Trees can each be hung or connected to the next higher tree with sections of sail.
  • the bottom sail tree, the deck tree at a fixed height directly above the deck is expediently firmly connected to the mast, so that the height of the sail is determined by the amount by which the top sail tree is raised.
  • the sail can be raised around a sail section, so that only the sail section between the top boom and the next lower intermediate boom is exposed to the wind, since the other sails are reefed and the sail booms one above the other on the mast on or in the bottom, which is designed as a tub Lying sail tree.
  • Such a setting is useful, for example, when the wind is strong, in order to be able to maneuver with the smallest possible sail area, which is then advantageously close to the center of gravity of the boat.
  • each sail tree with the sail section attached to it and extending to the next higher tree can have the outline of an airfoil profile.
  • the tree is designed as a frame construction with a corresponding outline, over which the canvas is given the shape of a wing.
  • an area of the aerofoil section located in front of the mast can have a frame part which can be pivoted about a central vertical axis, at the rear end of which remote-controlled drive means engage in order to be able to adjust the aerofoil profile by means of this pivoting flap at the front end and thereby with respect to the existing wind direction to achieve the best possible driving forces.
  • each sail section between a sail tree and the next higher sail tree comprises a first sailcloth that envelops the front foldable end of the wing profile, a second sailcloth that envelops the left area of the wing profile in which the mast is located, and a bow that envelops the right area of the wing profile third canvas.
  • the lateral plan of the sail is preferably elliptical.
  • the oars can have shafts mounted in the interior of the boat hull and can be adjusted with the aid of drive means arranged in the interior of the boat about the axes of the shafts in such a way that the required course holding forces with regard to the existing wind direction and the setting of the sail at the oar to prevent drift and heeling.
  • the leaf-like widenings of the rudders can each have a cross section corresponding to a wing profile.
  • This cross section can be changed in its geometry by hinged hinged front and / or tailgates.
  • a preferred constructive variant consists in that the hinged flaps are coupled with adjusting devices which are accommodated in a covering provided with an end plate and forming the end of the wing profile near the boat.
  • two oars can be symmetrically attached with respect to the keel edges of the boat hull and can be arranged at an acute angle of approximately 60 ° or more.
  • the outer or lower ends of the rudders have horizontal contact surfaces which are widened relative to the blade profile and are designed as a fluidic end plate.
  • the front flaps hinged to the rudder to adjust the wing profile can each be articulated to the main rudder blade and guided in the area of the fairing or its end plate by means of an elongated hole guide pin coupling. If the main rudder blade is swiveled around the rudder axis, the front flap must be swiveled and deflected due to the guide of the bolt connected to it in an elongated slot in the upper end plate in order to adjust the profile aerodynamically.
  • the keel line 22 and the upper side edges 24, 26 contain all imaginary triangles from the above-described observation, these triangles continuously decreasing to the point size towards the bow and stern so that the theoretical bow and stern points 28 and 30 meet at least theoretically .
  • the stern as indicated in FIG. 1, can consist of transparent material as a pulpit 58, while the bow can carry an attached or molded attachment. Since the triangular cross-sections that determine the outline of the boat hull decrease exponentially towards the stern and bow, the boat hull has approximately the shape of an ellipse in side view or plan view.
  • This elliptical or egg shape contributes to the desired high inherent rigidity of the fuselage, which in a practical embodiment consists of laminated mahogany wood, the wooden slats being glued with synthetic resin and glued onto prefabricated groups of ring-like frames with the outer triangular shape approximated.
  • the boat deck in strict compliance with the hull symmetry, consists of the convex triangular wall 16 which is convex upwards as shown in FIG. 2, an attachment 18 is extended to such an extent that the upper side 20 of the bow attachment is extended to improve the driving properties of the boat on the bow generally flat and tangent to the upper side edges 24, 26 of the fuselage. 1, the area of the union between these side edges lies between the vertical or small main axis H belonging to the ellipse construction and the bow 30.
  • the keel edge 22 of the boat hull is extended beyond the theoretical bow point 30 to the bow tip of the attachment 18, from the top thereof a bow edge 64 rises from which the skipper has an all-round view.
  • An opening 34 for receiving a sail mast 60 (FIGS. 3, 4) is arranged in the middle of the deck 16 and around the extension of the short semi-axis H indicated in FIG. 1.
  • the sail mast can have a triangular cross section and is supported and guided within the hull and can thereby be pivoted about its longitudinal axis.
  • the sail mast 60 belongs to a profile sail, which is indicated in its cross-sectional outline in FIG. 4.
  • several horizontal sail trees are slidably guided in the vertical direction, namely according to FIG. 3 an uppermost sail tree or top tree 68, an upper intermediate tree 76, a lower intermediate tree 80 and a so-called deck tree 84.
  • These sail trees consist of frame constructions, preferably of Light metal, the cross section of which is adapted to the shape of the wing and in which deflection rollers, cable pulls and winding motors are arranged in order to pull down the next higher tree by one step or by a height section and to reef the sail in this respect.
  • one or more deflection rollers 66 are mounted, via which the top boom 68 and possibly the entire sail are pulled up with the aid of cable pulling means 70.
  • the cable 70 is actuated by a lower winding motor C, which is arranged here within the cover tree 84, which is, for example, trough-shaped.
  • the deck boom 84 is attached to the mast 60 at the level of the boat deck 16 or locked to it and increases reefed sail - all sail trees lying on top of each other. From this state, the top boom is raised to any height when the sail is set by actuating the motor C, one or more intermediate sails then depending on the corresponding set overall sail height, for. B.
  • the uppermost sail section 74 between the top tree 68 and the upper intermediate tree 76 is opened or unfolded.
  • the next following sail section 78 is pulled up by taking along the upper intermediate tree 76, etc.
  • the number of sail trees and sail sections is arbitrary and does not necessarily have to correspond to that according to FIG. 3.
  • Each sail tree is connected to the next higher sail tree by at least one cable pull and a winding motor for reefing the sail section above.
  • cable pull connections only cable pulling means 72 are shown in FIG. 3 for reefing the sail section 82, which extends and is tensioned between the top boom 84 and the lower intermediate boom 80.
  • the cables 72 acting on the intermediate boom 80 are guided via deflection rollers in the cover boom 84 to a winding motor B 1, via which the intermediate boom 80 and thus all other sail trees and sail sections located above are reefed by one step until the intermediate boom 80 rests on the cover boom 84.
  • a front flap section 88 which has its own sail covering 96 with the contours similar to FIG. 4, is articulated at the front end of the top tree 68 via hinge or joint means 86.
  • front flap sections 90, 92 and 94 are articulated to the intermediate booms 76, 80 and deck boom 84, which, like the rear sail boom sections, consist of frame structures and are provided with separate sail covers 98, 100 and 102, respectively when reefing, fold in the same way as sail sections 74, 78 and 82.
  • the front flap section is each provided with a pivot arm 104 projecting into the rear main tree section, with which the flap section can be pivoted about a vertical axis 106 arranged on the front of the frame of the main tree.
  • a drive motor A 1... A4 is connected to the swivel arm 104 in order to be able to swivel the respective flap section up or down in the view from FIG. 4.
  • the control can be set up in such a way that the swivel drives A 1 ... A 4, as far as the sail sections arranged above them, are actuated together and in the same direction.
  • an adjustable or swiveling flap can also be provided at the rear end of the sail in order to adjust the wing profile and to be able to cross with the best efficiency against the wind.
  • the sail begins immediately above the hull and, according to FIG. 3, has approximately the same height when the top boom is rounded upwards with appropriate covering at the front and rear end. Also not shown is an embodiment in which two or more sails of the type shown in FIG. 3 are arranged one behind the other on the hull, in which case the hull is preferably designed to be stretched in a central region and may differ somewhat from the strict elliptical shape.
  • the hull in front of and behind its transverse center is equipped with a total of 4 rudders 42 which are inclined downwards and outwards, the arrangement of which results from FIGS. 1 and 2.
  • two propellers 38 can be provided as an auxiliary drive, the circles of which are shown in FIG. 2 and which start with bushings 36 for the drive deflection.
