Abstract

L'invention a pour objet un bateau comprenant au moins deux coques (12.1, 12.2), symétriques par rapport à un plan médian vertical, reliées par une plate-forme qui présente un fond (24), chacune des coques (12.1, 12.2) comportant un tableau arrière, une muraille extérieure (18.1, 18.2), une muraille intérieure, ainsi qu'une motorisation qui présente une hélice disposée dans un conduit qui débouche, via au moins un orifice latéral, sur la muraille extérieure (18.1, 18.2) et, via au moins un orifice arrière, sur le tableau arrière (16.1, 16.2) de la coque (12.1, 12.2), chaque coque (12.1, 12.2) ayant une section transversale effilée pour obtenir son enfoncement et garantir une immersion des conduits (44) lorsque le bateau avance à faible vitesse.The subject of the invention is a boat comprising at least two hulls (12.1, 12.2), symmetrical with respect to a vertical median plane, connected by a platform which has a bottom (24), each of the hulls (12.1, 12.2) comprising a transom, an external wall (18.1, 18.2), an internal wall, as well as a motorization which presents a propeller arranged in a conduit which opens, via at least one lateral orifice, on the external wall (18.1, 18.2) and, via at least one rear opening, on the transom (16.1, 16.2) of the hull (12.1, 12.2), each hull (12.1, 12.2) having a tapered cross section to obtain its penetration and guarantee immersion of the conduits ( 44) when the boat is moving at low speed.
