Abstract

Die Erfindung betrifft ein Mehrfachrumpfboot wie insbesondere Katamaran oder Trimaran. Als Auftriebskörper dienen langgestreckte Rumpfe 1 unterschiedlicher Quer­ schnittsgestaltung. Die Dicke der Rümpfe 1 nimmt im decksnahen Bereich bzw. im oberen Rumpfdrittel in Hori­ zontalrichtung von vorn nach achtern kontinuierlich bis zu einer Rumpfstelle größter Höhe sowie Breite zu und verringert sich hiervon wieder kontinuierlich bis zum Heckteil. Das vordere Rumpfende bildet eine schneiden­ förmig ausgebildete Bugspitze. Die Decksfläche 8 ist seitlich stärker gewölbt ausgebildet. Die Rümpfe 1 sind mittels Quertraversen 13, 14 miteinander verbunden. Zwischen den Rümpfen 1 ist ein Deck 24 angeordnet. Der Rumpfkörper 4 weist einen unterseitigen Kiel 5 auf, der sich mit weitgehend gleichbleibender Dicke von der Bug­ spitze 2 bis zum Heck 3 erstreckt und mit einer Mittel­ flosse 6 versehen ist. Die rohrskelettartig ausgebildeten vorderen und hinteren Quertraversen 13, 14 sind lösbar in Buchsen 19 eingesteckt, die in die Rümpfe 1 einlaminiert sind. Unterhalb der Decksflächen 8 der Rümpfe 1 sind an den einander entgegengesetzten außenseitigen Rumpfsei­ tenflächen 9 hakenförmige Halter 23 zur lösbaren Be­ festigung des Decks 24 angeordnet. The invention relates to a multi-hull boat like especially catamaran or trimaran. As a float serve elongated hulls 1 different cross pattern design. The thickness of the hulls 1 increases area close to the deck or in the upper third of the fuselage in Hori zontal direction from front to aft continuously up to to a fuselage point of greatest height and width to and decreases continuously from this until Tail section. The front end of the fuselage forms a cut shaped bow tip. The deck area is 8 laterally more arched. The hulls are 1 connected to one another by means of cross members 13, 14. A deck 24 is arranged between the hulls 1. The Hull body 4 has an underside keel 5 which itself with largely constant thickness from the bow tip 2 extends to the stern 3 and with a medium fin 6 is provided. The skeleton-like trained front and rear cross members 13, 14 are detachable in Inserted sockets 19, which are laminated into the hulls 1 are. Below the deck surfaces 8 of the hulls 1 are on the opposite hull egg tenflächen 9 hook-shaped holder 23 for releasable loading fixation of the deck 24 arranged.
