Abstract
The present disclosure generally pertains to a lateral displacement surf system and methods of laterally displacing a watercraft to generate wake. The lateral displacement system includes at least one pair of foils configured to be extended from a hull on a first side of the watercraft at a level of approximately the waterline. Upon forward movement of the watercraft with extended foils, the watercraft is rotated about its vertical axis toward the first side and generates waves sufficient for the conduction watersport activities on a second side of the watercraft. In some instances, foils are built into the hull and extended from this position, while in other instances the foils are attached to the hull using attachment structures. Rotation of the foils about an axis of rotation approximately perpendicular to a longitudinal axis of the watercraft alters the angle of attack of the foils relative to the waterline.
