One of my friends brought this one of a kind board with him to day. I think the board is over 12 years old and was originally used as a knee board. The fin is a jumbo! Our lighter riders are 140 and 170 pounds each and surf the goofy wake, which is OK on my boat, not quite as good as the regular wake. When we slowed down from a normal surf speed of 9.8 to 10 mph to about 8.5 mph the 170 lb rider was able to free ride. I didn’t ride the board, it’s far to small to support my weight. Our riders said that since the board has no edge it’s a little hard to control.
I don't know, it looks similar to the ocean knee board in the link. The board was marked with text that said it was the second proto type, so I guess it isn't a one of a kind. I’ll see Kevin this Saturday and ask him about the board.
I'm not sure how much effort this board is worth. We think the fin has too much drag and may replace it or cut it down.
I have been around plenty of kneeboards. I have to say I have never seen one quite like that. Very intersting design. Especially that huge fin. Board More/Work Less! J$
