ABSTRACT:
There is disclosed a catamaran either of the inboard or of the outboard type comprising a tunnel having a decreasing height from the bow to the stern thereof and so shaped as to provide an optimal distribution of the underlaying air pressure and in which, under the two flexible material tubular elements supporting the overlaying structure there are affixed tight rigid hulls which can consist of two or more parts in order to better fit the configurations of the waves by exploiting the resiliency of the tubular elements. The rear part of each hull is so designed as to form a small tunnel for preventing water from laterally exiting which is very important at the start and gliding of the boat. Thus the boat will be very soft, safe with high speed and reduced consume characteristics.
