MONOHULL SAILING WILL NEVER BE THE SAME AGAIN...

Bi-Planar Hull

Implicit to my sailing vessel design is a hard-chined hull that incorporates port and starboard semi-hulls configured one to the other such that each semi-hull is a separate (distinct) planing surface. Hull's configuration is in essence that of a bi-planer monohull. The consequence thereof being that vessel's attitude has to be maintained on an even-keel (either the port or starboard semi-hull) at all times. 'Even-keeling' is achieved by adjustments to traditional devices (steerage, ballast, sails) additionally, new devices (mechanical canting keel, canting rigging and adjustable ballast bulb) further contribute to maintaining one of the semi- hulls (port or starboard) on an 'even-keel'. Hull design incorporates sheer-strakes configured perpendicular to surface of the water thereby generating the lateral resistance required to counter leeward drift.
