Abstract:
1. A watercraft device comprising: a central body; two lateral hulls; and two or more connecting arms each connecting one of the two lateral hulls to the central body, such that the central body is in a raised position relative to the two lateral hulls, the two or more connecting arms having a given inclination relative to a vertical axis of the watercraft device, wherein the two lateral hulls and the central body have longitudinal axes parallel to each other, wherein the two or more connecting arms each comprise a first upper part connected to the central body and of a second lower part connected to one of the lateral hulls, such that the second part is submerged during navigation, and wherein each of the two lateral hulls comprises an elongated body having a substantially cylindrical symmetry, with an annular constriction defined between a fore portion disposed at a first longitudinal end of a lateral hull and an aft portion disposed at a second longitudinal end of the lateral hull, the fore and aft portions having widest cross-sections of the elongated body that taper to define the annular constriction therebetween.
