ABSTRACT:
A rectractable hydrofoil for watercraft wherein a linking mechanism connects all hydrofoils to a retaining assembly. The application of an external force to a hydrofoil above a threshold causes the release of the retaining means without requiring the reaction of the operator. A control assembly within the hull is utilized by the operator to complete the movement of the hydrofoil to an aft retracted position. The retaining assembly includes a releasable securing means for maintaining the hydrofoils in the retracted position.
