Definitions
- the present invention refers to a boat, and more specifically to a launch, which shows a series of building peculiarities aimed to provide it with a high resistance, great lightness and a perfect stability against possible side rolls, it all on account of the incorporation of a keel with a determined configuration such a boat type is known from EP-A-0 298 050.
- boats of this kind are widely known, built with light materials such as plastic, resins and polyester fibres, etc., and in which the keel is fastened on the lower surface of the hull, a watertight cavity being defined between both, that can be filled with air of with a filling material of low density.
- the part forming the keel shows in its centre a rib which projects in a more pronounced way in the bows area; on the sides of this central rib, surfaces markedly flat are each laid out, which progressively bend as they extend away the central area of the boat in order to form the lower area of the sides.
- This configuration of the keel, combined with the lightness of the boat, makes necessary to include in it a inner structure in order to provide it with a higher stiffness; on the other hand the configuration appreciably flat of the sides of the keel does not allow to obtain the wanted stability against the possible side rolls caused by the swell or by the moving of the crew on deck.
- the invention is defined in claim 1.
- the boat object of the invention keeping the same composition of elements (keel and upper body) than the conventional boats, shows features in the configuration of the keel aimed to provide it with a great side stability and a high resistance, which allows to suppress any chassis or inner structure of reinforcement.
- the lower surface of the keel defines three swellings appreciably semicylindrical placed in parallel to the longitudinal axis of the boat and which extend practically along the whole length of said boat, grooves or flutings of the same length being defined between said swellings.
- the central swelling can show a height higher than the two side swellings defining, only the former and in the front end, two side planes that converge on a central edge, the purpose of which is to facilitate the penetration of said central swelling in the water.
- the two side swellings are placed slightly sloping towards the rear area of the boat, adopting longitudinally a position appreciably slanting with regard to the central one.
- Another of the advantages of this keel is that of reducing the surface in touch with the water when the boat is displacing with a high speed, the stability being kept since said contact is established at the medium area by the central swelling and at the two sides by means of the other two swellings.
- the boat to the case consists of a hull (1) and an upper body (2) joint together by their perimetal edges (3), a watertight cavity being defined between them filled with air or with a filling material of low density, for instance polyurethane foam.
- the upper body (2) can define in its medium area any configuration or element proper for this kind of boats, in order to allow a correct handling of the boat and lodging of the passengers.
- the boat proposed here furnishes as main features that the keel (1) shows in its lower surface three swellings (4, 5 and 4), two of them on the sides (4) and one in the centre (5), appreciably semicylindrical, placed in parallel with regard to the longitudinal axis of the boat and which extend practically along the whole length of said boat, the grooves or flutings (6) being defined between said swellings.
- the mentioned swellings (4 and 5) show their front ends bent towards the upper area in order to facilitate the displacement of the boat on the water; the central swelling (5) shows also in said front end two side planes (51) that converge on a central edge (52) the aim of which is to allow the penetration of said boat into the water.
- the side swellings (4) are placed slightly sloping towards the rear area of the boat, adopting longitudinally a position appreciably slanting with regard to the central swelling (5), which in addition is more projecting that the aforementioned ones.

Claims (1)
- Bateau construit en une matière légère du type consistant en une coque (1) et un corps (2) supérieur, qui sont unis entre eux sur leurs bords (3) périmétraux et en définissant entre eux une cavité étanche à l'eau remplie d'air ou d'une matière de remplissage à faible densité, la coque définissant sur sa surface extérieure inférieure trois quilles, une au centre (5) et les deux autres, une de chaque côté (4), appréciablement semi-cylindriques, situées en parallèle à l'axe longitudinal du bateau, caractérisé en ce que les quilles définissent entre elles des entailles ou rainures (6) ayant essentiellement la même longueur que celle desdites quilles (4), en formant un angle droit à l'union des quilles lorsque l'on observe en coupe transversale, la ligne inférieure desdites quilles (4) étant progressivement élevée vers le haut depuis la poupe vers la proue en formant un angle avec la ligne inférieure de la quille (5) centrale, ladite ligne inférieure de la quille (5) central adoptant une courbure vers la proue et la quille centrale définissant deux plans (51) latéraux qui convergent sur un bord (52) central sur la proue du bateau.
