The flat bottoms were working great, but we wanted more speed. We felt that with added speed and drive out of turns, and better carry over the flat spots, we could further increase performance and add range to the size and type of waves that the boards would be effective in.
Again, we brain stormed with our Dad and came up with the single to double concave bottom design. The dramatic increase in speed that the concaves provided was just what those short wide boards (5’4″ to 6’3″ – 20 1⁄2 to 21 1⁄2″) needed. We now had short boards that were fast, positive and ultra maneuverable. It would now just be a matter of refinement.
The boards were working so well that we were confident that the single to double concave 3-fin design was the future of shortboards. The problem was that we were just a couple of kids from Oxnard and totally off the radar screen.
We decided to send a short letter out to some of the larger board manufacturers. The letter stated that we had a design that was seven years ahead of its time. The only company to respond was Bing Surfboards. Bing himself invited us down to show him what we had.
