Stabilizers (14.1, 14.2) coupled to associated stanchions (20.1, 20.2) and associated linkage assemblies (16.1, 16.2) on both sides of a central hull (12) provide for piercing or cutting through waves (76'). Aerodynamic surfaces (18.1, 18.2, 112, 114, 116, 118) over the linkage assemblies (16.1, 16.2) provide lift, as may a central keel (68) on the central hull (12). In one embodiment, each stanchion (20.1, 20.2) is coupled to the central hull (12) with a four-bar linkage assembly (16.1', 16.2') incorporating pivot bushings (78, 80, 86, 88, 92, 94, 98, 100) depending from the central hull (12) and the associated stanchion (20.1, 20.2) in cooperation with two pairs of non-parallel hinge pins (82.1, 82.2, 82.3, 82.4), respectively, with associated wedge-shaped aerodynamic surfaces (112', 114', 116', 118') attached to the linkage assembly (16.1, 16.2). The height of the stabilizers (14.1, 14.2) relative to the central hull (12) is adjustable using associated actuators (42.1, 42.2) in cooperation with the linkage assemblies (16.1, 16.2) either providing for, or responsive to, different operating conditions. Dampers (42') may be associated with or incorporated in the actuators (42.1, 42.2) to provide for dampening associated shock and vibration. |
