Definitions

  • the present invention relates to a watercraft with a hydrofoil arrangement according to the preamble of patent claim 1.
  • Hydrofoil arrangements generally consist of two hydrofoils arranged on either side of the hull, which can be adjusted in height by means of an adjustment unit of the hydrofoil arrangement on the hull, dependently and/or independently of each other.
  • the disadvantage of these hydrofoil arrangements is that they only have a limited range of functions and therefore cannot offer optimal lift values in every situation, unless they are extensively upgraded with adjustable flaps on the hydrofoils (hereinafter referred to as hydrofoils).
  • a watercraft which comprises a hull which has a hydrofoil arrangement in an area between bow and stern, which comprises two hydrofoils arranged on both sides of the hull, which are height-adjustable by means of an adjustment unit of the hydrofoil arrangement on the hull dependently and/or independently of each other.
  • the adjustment unit is hereby made up of two arc-shaped formed adjusting elements which are movably received on or within a plurality of guides of the hydrofoil arrangement provided on the watercraft, on the hull or on an adjusting element along a plurality of curved paths formed by the adjusting elements or the guide.
  • the US 4 582 011 A describes a multihull sailing vessel, such as a catamaran or trimaran, with adjustable wings, the wings of which diverge upwards and outwards from a point below the waterline of the vessel and in the plane of the vessel's longitudinal axis.
  • the wings are pivotally mounted at their inner lower ends to allow the wings to swing forwards and backwards to change the angle of attack of the wings.
  • the present invention is based on the object of eliminating the aforementioned disadvantages and of creating a watercraft with a hydrofoil arrangement which has a high range of functions, is easy to operate and offers low resistance in every position and has to overcome the lowest possible resistance at every speed and position.
  • the watercraft according to the invention (motor boat as well as sailing boat or ship) comprises at least one hull, which is in a Area between bow and stern has at least one hydrofoil arrangement, wherein the hydrofoil arrangement comprises at least two hydrofoils arranged on both sides of the hull, which are height-adjustable by means of at least one adjustment unit of the hydrofoil arrangement on the at least one hull dependently and/or independently of one another.
  • the watercraft is characterized in that the adjustment unit is formed from at least one arc-shaped adjustment member assigned to the at least two hydrofoils, which is slidably received on or within at least one guide of the hydrofoil arrangement provided on the watercraft, on the hull or on at least one adjustment member.
  • the hydrofoils are explicitly arranged only on an arc-shaped adjustment element, which - as will be discussed below - preferably occupies a single arc path on which the two opposing adjustment elements are slidably received.
  • the adjusting member is slidably received along a curved path formed by the adjusting member and/or the guide, wherein the curved path is open downwards with respect to the hull.
  • This type of foiling is suitable for both motor and sailing boats. Firstly, it is easy to use, easy to build and automatically reduces the required lift area at higher speeds, which leads to less drag and therefore makes higher speeds possible.
  • the draught of the hydrofoils can be changed very efficiently (e.g. 20 cm shift results in a 40 cm difference).
  • the adjustment should preferably be coupled with the rudder deflection.
  • the foil position can be freely selected. This is particularly useful when mooring, as the hull can be tied directly to the pontoon or quay and there is no need to board via the stern (Enata Foiler).
  • the guide of the hydrofoil arrangement is preferably located transversely to the centerline, can be opened from above and is attached in the ship's hull at an angle to the rear or is adjustable; adjustment depending on the wind conditions. This inclination also means that the adjustment elements are positioned forward in the water (outside the ship's hull) and thus provide buoyancy when the ship is still traveling in displacement mode.
  • the guide should have means for setting a fixed point for the adjustment elements and at the same time limit the adjustability x transversely to the centerline.
  • the following points are crucial for generating lift: 1. the inclined hydrofoil arrangement 2a) port hydrofoil, 2b) starboard hydrofoil, 3. rudder system with hydrofoil. Due to the curved hydrofoil arrangement, which is inclined forward in the underwater area, the buoyancy area is reduced the further the boat comes out of the water. Then only the mounted end wings and the rudder system carry the weight. If the hydrofoil arrangement on sailing boats is adjusted 20 cm to leeward using a pulley or similar, this side protrudes 40 cm deeper into the water than the windward side.
  • the wing adjustment In motorboats, the wing adjustment must be coupled with the steering deflection in order to absorb the centrifugal forces that occur when cornering as much as possible by tilting the boat and to redirect them back into the hull. Because of this adaptive tilt, no bending forces are exerted on the wings and thus no stumbling over them (high center of gravity is neutralized). Now even higher cornering speeds are possible (like with a three-wheeled (2 in front) motorcycle). The coupling should only be released during slow maneuvers or when docking.
  • the arched shape of the hydrofoil arrangement means that the entire weight of the boat is optimally distributed over the transversely installed guide. It can be built more lightly.
  • the boat With the hydrofoil arrangement raised, the boat is a) slippable, b) trailerable, c) fits in any normal box, d) can be launched from shallow shore areas, e) can be sailed well even in light winds because the braking wetted area in the water is reduced by pulling the arch segment up more or less.
  • the transversely installed guide makes the boat more stable or can be built more lightly.
  • Foil or wing tacks are possible.
  • the boat forgives sailing errors. It is stable when tacking and jibing, and windward capsizing is largely avoided.
  • the adjusting member 1100 is preferably formed from at least two adjusting member parts 1100', 1100" which are arranged along a common guideway formed by the adjusting member parts 1100', 1100" and/or the guide 112 and as described above and from the Figs. 1 to 3 downwardly open arched track S, which can be moved both together and individually.
  • adjusting element parts 1100', 1100" are accommodated so as to be displaceable relative to one another along the curved path S.
  • the adjusting member parts 1100', 1100" are accommodated so as to be displaceable together along the curved path S, so that a displacement of a first Adjustment element part 1100' to one side of the hull 10 causes this first adjustment element part 1100' to be aligned with respect to the horizontal ship plane E below a second adjustment element part 1100" laterally opposite on the hull 10.
  • the preferably at least two arc-shaped adjusting member parts 1100', 1100" can furthermore be movable relative to one another into an upper position L with respect to the hull 10 at a smaller angle W to one another than in their initial position A.
  • a further embodiment of the invention provides that the adjusting member parts 1100', 1100" are connected to one another in an articulated manner in their end regions 11000 by means of at least one joint 1101, hinge or similar suitable connecting means.
  • the articulated connection between the adjusting member parts 1100', 1100" can preferably be separable or detachable.
  • a particularly preferred embodiment of the invention provides that at least one fastening means is provided on the adjusting member parts 1100', 1100" or on the at least one joint 1101, hinge or similar suitable connecting means and the wing arrangement 11 comprises at least one means connectable to the fastening means, by means of which the adjusting member parts 1100', 1100" can be connected together or in accordance with Fig.4 are independently movable upwards with respect to the hull 10.
  • the at least one means can be arranged on a support part projecting upwards above the hull 10 or on a mast or on a component connected to the support part or to the mast, although other designs can of course also be considered. This means that the agent can also be placed further down on the hull.
  • the guide 112 of the adjusting member 12 and/or the adjusting member parts 1100', 1100" is preferably aligned transversely to the centerline of the hull 10 according to the drawing figures.
  • the adjusting element parts 1100', 1100" and/or the guide 112 are or can be inclined in the direction of the ship's bow below the ship's hull 10 in the side view of the ship's hull 10.
