A raft for a rapid flow water course amusement ride having a generally circular shaped hull fabricated in two sections with a surrounding floatation bumper and separate redundant floatation material in the bottom of the hull. A multiplicity of inwardly facing high-backed seats are disposed around the inner periphery of the hull with a circular hand-hold in the center. The circular construction and seat distribution and arrangement, coupled with the redundant floatation feature, provides a stable and safe floatation device which is especially adapted to endure abuse from collisions with the water course banks and obstructions disposed in the water course while carrying a plurality of raft riders.
