Wakesurfing boat and hull for a wakesurfing boat

Abstract

A wakesurfing boat includes a hull. A bottom of the hull defines a W-shape in cross-section, the W-shape including a central inverted V-shaped portion. A ballast system includes a plurality of sets of ballast tanks. The boat has a plurality of modes: a cruising mode with ballast tanks empty, a first portion of the bottom in contact with the water, a stern-down trim θ1; a ballasted static mode with ballast tanks filled with ballast water, the hull displacing more water, a larger portion of the bottom in contact with the water, a bow-down trim θ2; and a dynamic surfing mode with ballast tanks filled with ballast water, an intermediate portion of the bottom in contact with the water, and an intermediate trim θ3. A wake wave, generated in the dynamic surfing mode is larger than a wake wave generated in the cruising mode.

Description

FIELD OF THE INVENTION[0001]The present invention relates to boats and boat hulls. More particularly, the present invention relates to wakesurfing boats, and hulls used for wakesurfing boats.BACKGROUND OF THE INVENTION[0002]Wakesurfing is a watersport that is growing in popularity. A wakesurfer, initially being towed behind a boat via a tow rope, rises to his feet on a surf board in a body of water, (e.g., an ocean, a sea, a lake, or a river) similar to a waterskier or a wakeboarder. Ideally, the boat should generate in its wake a wave that mimics a size, a shape, and a duration of an ocean wave. If the wake wave reaches a sufficient size, the wakesurfer, unlike a waterskier or a wakeboarder, releases the tow rope, and rides the board on a crest and / or a face of the wake wave, traversing back and forth on the wake wave face as desired, similar to an ocean surfer.[0003]Until now, wakesurfers have been attempting to surf primarily in the wakes of existing cruising boats, waterskiing b...

AI Technical Summary

Benefits of technology

The invention results in an increase in resistance to the hull as it moves through water in the dynamic surfing mode. This is achieved through the combination of factors including the ballast tanks being filled or partially filled with ballast water, the at least second weight, the corresponding at least second displacement, the third portion of the V-shaped hull bottom being in contact with the body of water, the hull being in the third trim, and the increased amount of water passing through the funnel defined by the central inverted V.

Problems solved by technology

A problem with attempting to wakesurf behind traditional cruising boats, waterskiing boats, and wakeboarding boats, however, is that such boats fail to generate sufficiently large, sufficiently well-shaped, and sufficiently long-lasting wake waves to give the wakesurfer a long, satisfying ride.
