Presented is a highly efficient and stable ship concept that is at least partially supported by an artificially produced gas cushion(s). Addition of a stern bustle aft of the gas cushion(s) improves hull efficiency. Special location of water inlets for waterjet propulsors allows the inlets to take in the ship's boundary layer to thereby enhance the waterjet's efficiency. Other features of the invention include an aft stabilizer that can have trim capabilities, a forward stabilizer that can include trim capabilities and that can also provide an expansion of gas cushion area, and forward stabilizing fins that can retract into the gas cushion recess which is an advantage when operating in shallow water or near docks. A further enhancement includes water deflectors disposed mainly in a gas cushion recess(es) whereby impingement of a bow wave on such water deflectors adds to the overall lift and hence efficiency of the ship especially at low to medium speeds. Additionally, a system to recover pressurized gas that is leaving a gas cushion(s) and recycle it back into the gas cushion(s), after passing through a repressurizing system, is also offered. Further, hull efficiency is improved and air cushion blower power requirements are reduced by narrowing the ship's beam below the waterline aft.
