Abstract: A rudder assembly for self-propelled water craft, and particularly for a touring kayak. A rudder member is positioned within a notch of the rear of the keel of the craft, the exterior contour of this rudder member is made to augment the contour of the rest of the kayak hull to minimize changing the pattern of water flow around the craft. The rudder member is moved using an upstanding shaft attached to a disk within a recess in the rear of the craft, this disk being provided with starboard and port cables that extend to the cockpit of the craft. Axial movement of the cables is achieved using left and right foot pedals attached to slides within fixed channels. Provision is made for the adjustment of length of the cables, and for releasably locking one or both against axial movement.
