PERFORMANCE IMPROVEMENTS FROM A CONCAVE / CONVEX PLANING SURFACE – WIGGLE HULL

摘要

Concave camber can increase lift and Lift to Drag of a planing hull. The impact of camber and its limitations for arnplaning hull are reviewed, including model tests. The adverse impacts of low trims and excessive camber are discussed.rnA practical planing hull with significant concave camber must have convexity, at least forward to accommodate thernbow. This hull type is generically referred to as a Wiggle Hull and recent investigations to develop such a hull arernpresented. The prediction method developed for this investigation is described.
