Abstract
A vertical translation mechanism for reconfiguring the hull form of a reconfigurable vessel having independently movably side hulls and a center hull is disclosed. The vertical translation mechanism includes a hydraulic-force actuator and a nonmetallic bearing. The hydraulic force actuator comprises a rod that is disposed within a hydraulic cylinder. Responsive to changes in hydraulic pressure in the cylinder, the rod is extended or retracted therefrom. Movement of the rod controls the vertical translation of the center hull and its rotational attitude relative to the side hulls.
