Method and apparatus for minimizing drag of plural-hull craft |
| abstract |
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. The drag incurred between the longitudinally-aligned hulls is substantially reduced by shaping the adjacent bow and stern to be conjugates, or by use of a fairing which extends the contours of the forward hull into the aft hull. |
