Abstract

L'objet de l'invention s'adresse à la construction navale pour obtenir des catamarans bien protégés de l'avant. L'étrave centrale, dont la partie supérieure est identique à celle des monocoques, possède une partie inférieure qui, par des rapports entre la largeur des maîtres couples et des formes des lignes d'eau de la partie arrière immergée de l'étrave et des coques latérales entraîne la disparition de l'étrave. La quille de celle-ci, de profil effilé, remonte dans une liaison entre les coques latérales dès que les coques latérales ont atteint leur plus grande largeur. Deux voûtes non parallèles, de part et d'autre de l'étrave se réunissent derrière celle-ci en une seule qui continue jusqu'à l'arrière. La partie inférieure arrière de l'étrave peut recevoir des éléments mécaniques directionnels et propulsifs. Ceci intéresse particulièrement les navires à passagers et les bateaux de service désirant une grande stabilité.The object of the invention is aimed at shipbuilding in order to obtain catamarans that are well protected from the front. The central bow, the upper part of which is identical to that of monohulls, has a lower part which, by the ratios between the width of the master couples and the shapes of the water lines of the submerged aft part of the bow and the side hulls involves the disappearance of the bow. Its keel, of tapered profile, rises in a connection between the side hulls as soon as the side hulls have reached their greatest width. Two non-parallel arches, on either side of the bow meet behind it in one which continues to the rear. The lower rear part of the bow can receive mechanical directional and propulsion elements. This is of particular interest to passenger ships and service vessels requiring great stability.
