Abstract:
A recreational device that supports a seated human rider while the rider and the device are towed behind a powered watercraft, comprising:an elongated board having a front end and a back end;a seat extending from the board for supporting the buttocks of the seated rider at a position spaced above the board;a strut depending from one of the board and the seat, said strut defining a plane of symmetry;a blade assembly secured to the strut, the blade assembly having a front blade and a rear blade connected by a fuselage, said front blade including a first portion defining a first surface on a first side of said plane of symmetry and a second portion defining a second surface on a second side of said plane of symmetry, said first surface and said second surface directing water toward the plane of symmetry upon landing of the front blade on water,wherein said front blade has a leading edge and said rear blade has a first edge and a second edge, said rear blade mountable on said fuselage in a first position wherein said first edge defines a trailing edge of said blade assembly and said rear blade mountable on said fuselage in a second position wherein said second edge defines a trailing edge of said blade assembly,wherein the greatest perpendicular distance between said leading edge and said first edge when said rear blade is in said first position is longer than the greatest perpendicular distance between said leading edge and said trailing edge when said rear blade is in said second position.
