ABSTRACT:
A kayak 10 having at least one hull section 16, 18 whose volume may be adjusted to enable said hull section to be submerged by a boater for water acrobatics comprises spaced longitudinal frames 22, 24 connected to the hull section. The spacing between the frames may be varied to proscribe the configuration of the hull section over a substantial part or short segment of its length. The frames 22, 24 may be interconnected by flexible cabling 30, 32 or by a mechanical scissor linkage 48 to change this spacing and adjust the volume. Supportive framework (70, 72) is provided to prevent total collapse of said hull sections.
