Abstract

A wakesurfing boat (10) and a hull (12) for a wakesurfing boat. The hull includes a bow (14), a stern (16), port (17) and starboard (18) bulwarks, and a bottom (20) having a preselected length extending from the bow (14) to the stern (16).
The bottom (20) is configured with a substantially central ridge (22) and port (24) and starboard (25) ridges extending below the respective port and starboard bulwarks (17, 18) to define a substantially M-shaped bottom in cross section with concave portions to port and starboard of the substantially central ridge.
Port and starboard laterally rounded sponsoons extend below the respective port and starboard bulwarks proximate the stem. A trim wedge projects below the stem. A first rounded stem portion extends below the stem aft of the trim wedge, and a second rounded stem portion extends from the port sponsoon to the starboard sponsoon. Ballast tanks (42a, 42b, 43a, 43b, 44a, 44, 45, 46) supported by the hull, are selectively fillable with ballast water. In a dynamic surfing mode, with ballast tanks partially or fully flooded, increased water flowing through the port and starboard concave portions, combined with increased ballast, and increased displaced water, increases water resistance to the hull, resulting in a larger wake wave.
Water passing around the rounded lateral sponsoons, past the wedge trim, and past the first and second rounded portions of the stem is directed toward a convergent zone in the wake, resulting in an improved wake wave shape.
