Abstract: A steering system for hydroski-borne watercraft eliminates the need for conventional steering mechanisms such as rudders or thrust vectoring from propulsion units. Complete steering and navigable control is achieved by rolling or otherwise banking individual hydroskis thereby creating a side force on each hydroski. This force is proportional to the sine of the bank angle or roll angle. The sum of the forces and moments from the individual hydroskis are of sufficient magnitude and can be appropriately balanced to effect coordinated watercraft steering and navigable control.
