ABSTRACT:
The present invention entails a rudder-tiller control system for a boat. In one embodiment of the present invention, a multi-hull boat is shown with a plurality of rudders, a rudder-tiller arm extending from each rudder, and a tiller connector bar operatively interconnected to each rudder-tiller arm through a universal type connector assembly. The connector assembly operatively interconnected between respective rudder-tiller arms and the tiller connector bar allows at least three degrees of freedom and relative movement between respective rudder-tiller arms and the tiller connector bar. More specifically, each connector assembly includes a housing having a ball joint rotatively confined within a spherical shaped cavity within the housing. Secured to the ball joint and extending therefrom is a connecting pin. In a connected environment, the housing of the connector assembly is secured to the tiller connector bar while each rudder-tiller arm is securely connected to the connecting pin extending from the ball joint. Consequently, the rudder-tiller arm may rotate with respect to the tiller connector bar about the center point of the ball joint. The result is the connector assembly provides a generally rigid joint while at the same time providing relative rotational freedom between the rudder-tiller arm and the connector bar about the center point of the ball joint through 360 degrees of motion in a horizontal plane and approximately 300 degrees in both fore-and-aft and side-to-side vertical planes.
