Definitions

  • the present invention relates to a sailing-boat hull.
  • the object of the present invention is to provide a hull which, as well as optimising the above requirements, enables a particularly fast and stable craft to be produced.
  • the hull has a bottom which is provided with a projecting keel having a substantially U-shaped cross-section with tapered ends connected to the stern and bow regions of the hull respectively, and which is connected to the sides by means of two longitudinal channels of rounded section connected to the keel in the bow region so as to define two longitudinal side portions of the bottom which have rounded sections, are situated at a higher level than the keel and extend from the stern for a substantial length of the bottom.
  • the structure of the hull is particularly rigid both in bending and in torsion and does not need special ribbing or bulkheads.
  • the particular shape of the bottom enables it to have a reduced freeboard and consequently reduced passive wind resistance, whilst the habitability of the interior and the headroom are kept unaltered.
  • Another advantage of the hull according to the invention concerns the small draft and high transverse stability of the hull, which enables lighter ballast to be used.
  • the particular U-shape of the keel enables the loads to be concentrated in a more central and lower position than is possible in conventional hulls, thus enabling the ballast to be reduced by up to 50% compared with conventional hulls with the same displacement.
  • a further important advantage concerns the high speed which can be reached by the hull, particularly at planing speeds.
  • the shape of the keel with a substantially flat bottom enables the vertical hydrodynamic force to be used to lift the two longitudinal side portions of the bottom from the surface of the water with a drastic reduction in the wetted area. At planing speeds therefore, maximum speeds considerably higher than those attainable by conventional hulls of the same waterline length can be reached.
  • Another important advantage concerns the fact that a hull according to the invention makes little leeway.
  • the side walls of the U-shaped keel act as particularly effective vertical stabilisers even at large heeling angles.
  • the longitudinal side portions of the bottom have downwardly diverging appendages with supporting feet, each appendage being hinged at its rear to a rudder blade.
  • a sailing-boat hull is generally indicated 10 and has a bottom or quickwork C, sides F, a bow P, and a flat transom S.
  • the bottom C is provided with a keel 12 having a U-shaped cross-section which is connected at 12a and 12b respectively to the bow P and to a zone S1 adjacent the transom S. Beside the keel 12, the bottom C has two longitudinal channels 14 of rounded section which extend from the transom S for approximately two thirds of the length of the hull 10 and then become rounded steps 14a connected to the bow P and laterally to the sides F of the hull.
  • Two longitudinal side portions 16 of the bottom are defined between the longitudinal channels 14 and the sides F of the hull and are situated at a higher level than the keel 12.
  • the side portions 16 have substantially rounded sections and extend from the stern for approximately two thirds of the length of the boat to converge with the bow steps 14a.
  • the shape of the keel 12, the longitudinal channels 14 and the side portions 16 is clearly defined by the cross-sections of Figures 2 and 3, in which the waterline of the hull 10 is indicated L.
  • the side portions 16 have flat diverging appendages 18 provided with lower support portions 18a.
  • a rudder blade 20 is articulated to each of the appendages 18 and projects axially from the transom S. It is clear that, when the boat is taken out of the water, the hull 10 does not require any launching cradle since it rests directly on the ground, indicated K in Figure 3, in correspondence with the keel 12 and the portions 18a of the two diverging appendages 18.
  • the boat provided with the hull 10 can be provided with an inboard/outboard engine, whose propeller emerges at A in correspondence with the transom S.
  • the vertical stabilisers which resist the leeway are essentially the lateral vertical surfaces of the keel 12, whilst the bottom surface of the keel 12 contributes, particularly at planing speeds, to the progressive raising of the lateral portions 16 to the surface L, thus enabling considerable speeds to be achieved.
  • the hull 10 may be provided with a centreboard 30 ( Figure 4) with a shaped ballast 30a.
  • the centreboard 30 may be of the type which can be inclined laterally by means of a hydraulic actuator operated (in known manner) by the boom.
  • the particular shape of the bottom C enables a seat (not illustrated) to be formed in correspondence with the longitudinal channels 14 for housing a flexible ring-shaped inflatable envelope which, in its inflated configuration, ensures the buoyancy of the boat if the hull is flooded.
