ABSTRACT:
An apparatus and method are disclosed for increasing the low speed maneuverability and the stability of sea-going vessels. The apparatus includes a linkage assembly which connects a primary vessel or sub-vessel to a secondary, steering vessel or sub-vessel such that the steering vessel or sub-vessel may yaw with respect to the primary vessel. In preferred embodiments, the linkage assembly includes a pair of linkage arms that are pivotally connected to the primary and secondary vessels, one linkage arm on each side of the secondary vessel. The apparatus may further provide elements to actuate and control the yawing motion of the steering vessel or sub-vessel.
