Abstract

Improvements in hydroplane boats in which a unique combination of diagonal and transverse planing surfaces provides stability and makes the boat safe to operate at high speeds and at the same time forms an air cavity under the center of gravity of the boat which is pressurized by air scoops and regulated by various devices to support the boat on an air cushion and improve its high speed efficiency without decreasing its stability in any mode of operation.
