ABSTRACT:
A catamaran watercraft having a pair of parallel pontoons which pivot along their respective longitudinal axes. The pontoons are each preferably triangular in cross section, having a planar bottom surface and a linear top surface forming the longitudinal axis of rotation. A deck is hingedly supported by the linear top surface of each pontoon so as to be pivotable about the longitudinal axis of the pontoon. A control bar member or control wheel is included for simultaneously pivoting the pontoons relative to the deck. The rotational movement of the pontoons provides directional control of the watercraft without the use of a rudder.
