Abstract

An adjustable sponson for a personal watercraft allows the vertical position and the angular orientation of the sponson to be adjusted to suit the particular size and riding style of each rider. Each adjustable sponson includes a sponson body. At least one locking mechanism releasably attaches the sponson body to the hull side. A guide mechanism allows the sponson body to move vertically relative to an outer chine of the watercraft hull when the locking mechanism is loose. The guide mechanism also permits the ends of the sponson body to move independent of each other so that the angular orientation of the sponson body relative to the chine can be altered. When locked, the locking mechanism prevents movement of the sponson body over the hull side surface.
