Abstract
A vessel (10) has a semi-displacement or semi-planing round bilge hull (11) characterized by low length-to-beam ratio (between about 5.0 to 7.0) and utilizing hydrodynamic lift. The bottom (15) of the hull (11) rises toward the stern (17) and flattens out at the transom (30). Four waterjet propulsion units (26, 27, 28, 29) are mounted at the transom (30) with inlets (31) arranged on the hull bottom (15) just forward of the transom (30) in a high pressure area. Water under high pressure is directed to the pumps (32) from the inlets (31). Eight marine gas turbines arranged in pairs (36/37, 38/39, 40/41, 42/43) power the waterjet propulsion units (26, 27, 28, 29) through combined gearboxes (44, 45, 46, 47) and cardan shafts (48, 49, 50, 51).
