ABSTRACT:
This invention relates to actuators for small sailing craft. Fins extend downwardly from opposite sides of the craft and pivot together when the craft lists. The pivoting tends to right the craft. When righted, the fins function like centerboards to stabilize the craft. Preferably, the fins are linked to a pendulum which responds to the listing of the craft.
