Surfboard fin for generating surfboard lift and method of use
Abstract:
The present invention relates to a lifted fin apparatus comprising one or more lifted fin elements with foiled tin components for a reduction of pressure and drag and an increase in surfboard lift as well as a method of achieving surfboard lift through, the use of said apparatus. Generally, the lifted fin apparatus comprises two or more lifted fin elements exhibiting a foil design on one or more of the fin surfaces. The individual fin elements may comprise a substantially vertical fin attached to a first edge of a base member and oriented at a substantially 90° angle in relation to the bottom surface of the surfboard or to the first edge of the base member. The fin elements may further comprise an angular fin mounted to a second edge of the base member at one end and the lower portion of the first, fin at the other end. In said embodiment, a bend or elbow is formed between a first fin component of angular fin and base member proximate the point of attachment at second edge of base member. Alternatively, the base member may not have a defined second edge representing the intersection between base member and a first fin component of angular fin, but rather the base member and the angular fin may be manufactured as a unitary structure with a bend or elbow between base member and a first fin component as described below.
