Making surfboards is a specialized trade. You may be able to get schooling on composites but actually knowing the what and how of surfboard design is pretty much a learn by experience endeavor.

Most people that ride surfboards don’t think or maybe even don’t care about what makes the board they ride work the way it does. And that’s fine, but there are nuts like myself that spend hours processing through ideas about design and trying to work through problems experienced in the last surf session and how the board you were riding might be improved, or, at least how your surfing may be improved by working through a certain board design.

I see the surfboard as mainly a foil. The over all dynamic of the surfboard foil will determine how the board will ride. How much or little curve the foil has on the bottom as well as the top (deck), where and how the thickness is distributed through its length, how the deck and bottom contours are shaped from rail to rail. The curve of the outline. All play together to make the surfboard of your choosing react to wave and rider.

Riding certain board designs will determine how you surf. If you try to surf a board against the way it’s meant to be ridden over all performance will be poor, for both board and rider.

An easy example of this can be best understood by the difference between short board and long board surfing. Short boards must be ridden with a low center of gravity, knees always bent, any body extensions are short and returned to that low center. If you stand straight up on a short board, unless you are moving fast along the wave, the board will sink. A long board on the other hand you will ride almost at a full stand up. Sure you’ll bend the knees but because of the foam volume if you stand straight up the board will continue to glide down the face of the wave.

Those examples may be extreme but, you can take just about any surfboard design and if you want to get its maximum performance you need to know why it will ride a certain way and not go against it.

Single fins ride different than tri fins. Tri fins ride different than twin fins. Do you want to ride a certain board design? Learn how it works, usually by riding it, and have some fun with it. Think through your moves and try to understand what’s going on. Do you have to ride one certain kind of board? No. Is one design better than the others? Not really, it just depends on what it’s for, so ride it in conditions and style it’s built for.

You can experiment, learn, and grow your surfing.
