rudders

Wooden rudders for the radio-controlled proa model. The rudders are based on the NACA 0012 profile. Also seen are wooden sleeves for the rudders. In this design, the rudders can be lifted up out of the water for the shunting maneuvers, maneuvers requiring the proa to reverse direction. One rudder is used for one direction of travel and the other is used for the reverse direction. The rudders can slide through the sleeves.
