ABSTRACT:
Generally, different boats are needed for pulling waterskiers, sailing, fishing and camping. The reason for this is that a boat which would efficiently operate for all of these purposes, and which was sufficiently small to be trailerable, has not been available. Herein, a boat structure (10) is disclosed having a central hull (12) which is of a width (W) at the waterline (26) when floating at rest. A pair of side hulls (32,34) have infacing sides (36,38) which are equally spaced a distance which is from about two-thirds to about four-thirds of the width (W), from the plane (24). Bottom portions (44,46) of the side hulls (32,34) are spaced above a lowermost portion (14) of the central hull (12) and are positioned below the water line (26) when the hull (12) is at rest. Substantial horizontal port and starboard bridges (52,54) are spaced above the waterline (26), extend substantially the length of the side hulls (32,34) and connect top portions (40,42) of the side hulls (32,34 ) to upper portions (20,22) of lateral sides (16,18) of the central hull (12).
