A technique is provided for steering and navigating a watercraft. The technique provides for dual electric motor propulsion units aft of a transverse centerline of the watercraft. A forward thruster system is provided forward of the transverse centerline. The rear drive units provide components of thrust for navigating the craft through straight-ahead settings and turning settings. The forward thruster system provides additional thrust components for moving the watercraft in a "sliding" direction, and for providing additional turning thrust. The system is particularly well suited to slow-speed navigation, such as for recreational fishing, as well as for close quarters navigation and docking.

1. A propulsion system for a watercraft, the watercraft including a hull having a longitudinal centerline and a transverse centerline, the system comprising:a forward propulsion unit disposed forward of the transverse centerline and configured to produce thrust directed transverse to the longitudinal centerline; first and second aft propulsion units mounted to the hull at symmetrical locations and at angled orientations with respect to the longitudinal centerline, each aft propulsion unit being configured to produce at least a thrust component parallel with the longitudinal centerline; and a system controller coupled to the forward and aft propulsion units and configured to control operation of the propulsion units to produce a resultant thrust for navigating the watercraft.
