Low drag multi-hulled craft - has vertical flow control fins set between hulls to provide stability and laminar flow patterns

摘要

The multi hulled craft has special fins set vertically between the hulls to provide stability when travelling the fins also set up laminar flow patterns over the hull. The drag is greatly reduced within increasing the complexity of the craft. The fins extend over all or part of the length of the passages between the hulls. They enable large multi hulled craft to be used with a minimum of thrust, and in heavy seas.
