ABSTRACT:
An adjustable sponson for a watercraft includes a coupling mechanism that allows the angular orientation of the sponson body relative to the hull of the watercraft to be varied by the operator of the watercraft without the use of any tools. The coupling mechanism also secures the sponson to the hull of the watercraft, maintaining the desired orientation of the sponson.
