MARINE VESSEL HULL WITH A LONGITUDINALLY VENTED TRANSVERSE STEP

摘要

A marine vessel hull, and marine vessels comprising at least one such hull, comprising a non-entrapment hull having at least one longitudinally vented transverse step, each longitudinally vented transverse step comprising a transverse step extending from starboard to port, and one or more longitudinal steps extending forward therefrom. One or more longitudinal steps may also extend aft of an aft-most longitudinally vented transverse step, and may converge to a relatively lesser depth at the stern than a maximum depth at a location fore of the stern. The one or more longitudinal steps may gradually transition to a maximum depth aft of a discontinuity introduced by a forward transverse step. The hull may also have one or more longitudinal step tunnels.

1. A marine vessel hull having a fore, aft, port, and starboard, the hull comprising a non-entrapment configuration having:
at least one longitudinally-vented transverse step, each longitudinally-vented transverse step comprising:
a transverse step extending from starboard to port across a bottom of the hull; andone or more forward longitudinal step portions connected to and extending forward from the transverse step, each longitudinal step portion defining a longitudinal air pathway configured to feed air into the longitudinally-vented transverse step when the hull is in motion on a body of water.
