Abstract:
1. A fin structure for use attached to a water sports board, comprising: a body having a first end and opposite second end, the body being defined by a first sidewall and a second sidewall that are at least partially spaced apart from one another so as to define a single generally kite-shaped opening therebetween, wherein the first and second sidewalls extend distally from the first end toward the second end to define an upper region and a lower region, wherein in a direction from the first end towards the second end, the first and second sidewalls initially diverge relative to one another to define equal length first segments so as to comprise the upper region and then converge relative to one another to define equal length second segments so as to comprise the lower region wherein the first segments have a length that is greater than the second segments such that the upper region is taller than the lower region, and the body further comprising a bottom portion comprising an arcuate shaped wall and integrally connecting the first and second sidewalls at the second end, wherein the first and second sidewalls intersect at the first end and are symmetric relative to a longitudinal axis that bisects the first end and the bottom portion, wherein each of the first and second sidewalls have an inner surface and an outer surface opposite to the inner surface defining a cross-section, wherein the outer surface has a greater radius of curvature than the inner surface in the upper region and wherein the outer surface of the sidewalls in at least a portion of the lower region has a greater radius of curvature than the inner surface, wherein the body has a maximum height that is greater than a maximum width of the body; and a mount disposed at the first end of the body, wherein the mount is configured to attach the kite-shaped body to a bottom surface of the water sports board.
