Abstract
A sliding fin for a surfboard includes a base having a planar tab with an upper flange, a large fin piece having a first indentation, and a small fin piece for mating face-to-face with the large fin piece. The second fin piece has a second indentation that forms a channel that has a cross-sectional shape corresponding to a cross-sectional shape of the planar tab and upper flange, the channel being longer than the width of the planar tab, the small fin piece being translucent to enable the planar tab in the channel to be seen, the large and small fin pieces being slidable relative to the base on the planar tab.

A sliding fin for a surfboard, the sliding fin comprising:
- a base having a planar tab with an upper flange;
- a first fin piece having a first indentation;
- a second fin piece mated face-to-face with the first fin piece and having a second indentation that forms a channel that has a cross-sectional shape corresponding to a cross-sectional shape of the planar tab and upper flange, the channel being longer than the width of the planar tab, the second fin piece being translucent to enable the planar tab in the channel to be viewable, the first and second fin pieces being slidable relative to the base on the planar tab.
A surfboard comprising:
- a board having a top riding surface and a bottom surface;
- a base having a planar tab with an upper flange, and having one or more protrusions extending below the base to mate with the bottom surface of the board;
- a first fin piece having a first indentation;
- a second fin piece mated face-to-face with the first fin piece and having a second indentation that forms a channel that has a cross-sectional shape corresponding to a cross-sectional shape of the planar tab and upper flange, the channel being longer than the width of the planar tab, the second fin piece being clear to enable the planar tab in the channel to be seen, the first and second fin pieces being slidable relative to the base on the planar tab.
