Abstract
A surfboard-based powered water craft is propelled by gas or electric power plant. A water jet pump supplies water under pressure, which is exhausted through a steering nozzle. A steering shaft, carried by the surfboard-based body, pivots in response to movement of a steering arm. The steering arm pivots about a vertical axis and a horizontal axis. The weight of the power plant is carried forward the center, whereby a rider on top of the surfboard based body tends to balance the weight of the power plant.
