Plural-hull sailing craft and methods for sailing craft

摘要

A plural-hull craft incorporates separate hulls pivotally attached at the extremities of an interconnecting structure, which hulls may be rotated either separately or in unison to longitudinally align two or more hulls with substantial hydrodynamic continuity, whereby leeward hull buoyancy is increased to improve longitudinal stability. In such configuration, the aligned hulls may be horizontally counterrotated into an approximate arc for turning the craft, or may be counterrotated horizontally into the approximate shape of a cambered airfoil so as to provide sideways lift to counteract lateral drift. Additionally, at least one hull may be individually rotated about its pivotal attachment point to maneuver the craft.
