ABSTRACT:
The steering of a human powered pontoon aquatic vehicle is improved by arranging the pontoons in three articulated sections. The forward and aft pontoon sections are rotated in reciprocal directions with the forward sections being rotated in the direction of the desired turn. The vehicle includes a support frame attached to the forward and aft pontoon sections upon which a seat is mounted. A central frame member attached to the central pontoon is shifted laterally with respect to the support frame in order to rotated the forward and aft pontoon sections. The forward and aft pontoon sections are connected to the central pontoon section by interlocking hinges which permits convenient disassembly of the vehicle for transportation.
