MULTIHULL STEPPED PLANING BOAT WITH MULTIPLE INDEPENDENT ELASTIC PLANING SURFACES

WIPO Patent Application WO/2022/151889

A1

A multihull stepped planing boat with multiple independent elastic planing surfaces includes: a main hull, X front planing sub-hulls arranged side by side under a front portion of the main hull, and Y rear planing sub-hull arranged side by side under a rear portion of the main hull; wherein X and Y are positive integers, and 3≤X+Y≤8; the X front planing sub-hulls are equally spaced, and the Y rear planing sub-hulls are also equally spaced; there is a gap between the X front planing sub-hulls and the Y rear planing sub-hulls. The planing surface of the main hull is formed by a plurality of independent and spaced sub-planing surfaces. There is a certain elastic buffer space between each sub-planing surface and the main hull, and the shock absorption structures can absorb most of the shocks, thereby reducing the impact of water surface waves during high-speed navigation.
