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.
