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.
Claims8
A watercraft comprising a hull, at least one sponson and a coupling mechanism which attaches the sponson to the watercraft hull, the coupling mechanism including a guide mechanism that establishes a travel path for the sponson over a surface of the watercraft hull, a drive mechanism that moves the sponson along the travel path, and an actuator that drives the drive mechanism, the actuator being powered by a motor.
An adjustable sponson system for use with a watercraft hull comprising at least one sponson body and a coupling mechanism which attaches the sponson body to the watercraft hull, said coupling mechanism including a guide mechanism that principally defines a travel path for at least a portion of the sponson body over a surface of the hull, at least part of said coupling mechanism extending from said portion of said sponson body to couple with an adjacent surface of the watercraft hull so as to hold said sponson body portion in contact with the adjacent watercraft hull surface, and a motorized drive mechanism operable between the watercraft hull and the sponson body to move at least a portion of the sponson body along the travel path.
