Hybrid hull will meet all luxury yacht speed needs

摘要

In recent years, the design of luxury motor yachts has focused on ever-higher speeds. Design briefs often state speeds that would require traditional "displacement"-type motor yachts to be pushed over the hull speed into, or just over, the primary resistance hump, to the semi-displacement regime.rnTo obtain semi-displacement speeds, owners and yards almost automatically think of a hard chine hull form (basically derived from a planing hull form) to achieve good performance at the maximum speed. However, a hull well designed for a speed of, say, 25 or 30knots is often not very efficient at running at 13knots. In reality, most of these yachts hardly ever run at top speed, but mostly operate at a much lower cruising speed.
