Abstract
A rudder assembly for sailboats which comprises a rudder support frame, a rudder blade, a tiller frame, a pivot bracket, and a lever. With the rudder blade in the lowered position, the weight of the tiller arm bears down on the pivot at the junction of the lever and the pivot bracket preventing the upward movement of the lever and locking the rudder blade in place. To raise the rudder blade, the tiller is lifted up, pulled forward, then pushed down, causing the lever to rotate and pulling the upper rear portion of the rudder blade forward. Adjustments in the rake angle of the rudder blade and the force required to kick up the rudder blade may be made.
