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.
Claims8
Actuators for use with a small sailing craft to stabilize the craft and to provide self-righting capacity, comprising a pair of fins pivotally mounted and disposed on opposite sides of the craft, each fin extending downward below the hull of the craft to act like a centerboard, a tie rod connecting the fins to allow their simultaneous pivoting, and a pendulum for actuating the simultaneous pivoting when the craft lists to turn the fins through the tie rod so that the list of the craft will automatically be reduced.
Actuators for use with a small sailing craft to stabilize the craft and to provide self-righting capacity, comprising:
- (a) a pair of fins pivotally mounted and disposed on opposite sides of the craft, each fin extending downward below the hull of the craft to act like a centerboard, and adapted to stabilize the craft and to provide self-righting capacity for the craft;
- (b) mechanical means connecting the fins and adapted for allowing the simultaneous pivoting of the fins;
- and
- (c) means for actuating the simultaneous pivoting of the fins when the craft lists, directly mechanically connected to the mechanical means connecting the fins, adapted to turn the fins so that the list of the craft will automatically be reduced, and including a horizontally projecting pendulum.
