Patent ID: 8813665

Claim:
A dual-rudder control mechanism suitable for use in the sailboats ( 1 ), comprising an extendable pivot ( 8 ) having each end a respective rudder, mechanism ( 20 ) for extending the pivot ( 8 ) length for rotating the rudders relative to the pivot ( 8 ), a control mechanism being responsive to tilting angle of the sailboat ( 1 ), wherein the control mechanism activates or deactivates the mechanism ( 20 ) for extending the pivot length in response to a threshold tilting angle of the sailboat body, wherein the rudders can be rotated independently from one another when the mechanism ( 20 ) is activated, wherein the mechanism ( 20 ) for extending the pivot ( 8 ) length is a solenoid actuator, and wherein the solenoid actuator comprises a pin ( 22 ) penetrating into respective pin hole ( 23 ) that are opened in the radial direction to the inner pivots ( 9 ) and outer pivots ( 10 ) by actuating the solenoid actuator.
