The length of the FRIEND tiller extension can be simply and precisely adjusted. It can also be used as a tiller restraint for setting the desired rudder precise position in 35 stages. If the handle on spring-loaded folding hook is hooked onto the cockpit wall and the tiller extension extended, it can be unlocked and the rudder angle changed by gently turning the sleeve - it is not necessary to press a button. When the sleeve is released, the FRIEND automatically locks the tiller in the new position.
