I want to start a discuss about the limiting factors of certain design aspects in surfboards in relation to wave size. In particular flex and the swallow or fish tail design. The purpose of the fish tail being to split the tail into two “half-pins” to allow a wider tail area and a wider board while being able to hold under higher speeds. While flex in big waves has been written-off as uncontrolable or too much to control. Of course all surfboards and all materials flex under load. The question I propose it whether flex can be built effectively on big-wave boards to control the potential energy of gravity and momentum in a way that can be used to generate more speed. By big waves I mean double-to-triple overhead as the lower limit to the limit of paddle in surfing(which is a grey area) as the upper limit.
My thinking is a shorter, thicker, more manueverable surfboard may be possible for riding larger waves, rather then the traditional guns, but of course it’s a complicated and difficult prospect. There are many factors to consider in building a board for such situations and testing concepts are difficult. A more bouyant core and a stronger shell could help reduce surface area, length, and weight. I know a heavier board is easier to get into a wave, which in another reason why I want to reduce the surface area. If there is less surface area to compete with wind, it should be easier to get a board in earlier.
I might be spending a month in Puerto Escondido this summer…I’m thinking about buiilding a few compsand style boards to test out. An idea I have is .75Lb EPS core with basalt glass/paulownia sandwich, rails either out of bamboo or paulwnia and possiblly wrapped with carbon or a kevlar/carbon hybrid. As far as dims go, thats where I’m fuzzy…
So let’s hear it…from your experiences what are the limits??
and yea I know I’m crazy…I spend alot of time on the bottom of pools, I might be slightly retarded by now…
I’m at work now, I’ll design a board later and post the file…
Well - you gotta catch the wave first and formost, after that you can think about what you want to do. Seems to me the problem is the wide varity of conditions one encounters on “big” days. Chop the size of small waves on the drop. Currents ripping like a river. My understanding is - except for “big” mush - speed isn’t usually the issue, but control. And, on many levels, when it’s clean, minimal current/chop etc. once you’ve made the drop, you probably want a lot less board to “drive.”
There have been interesting threads in the past regarding wave cathing vis-a-vis some of the points you’ve raised, such as: Narrow tail for “less surface area” may = less drag, easier to “drop in.” V. Wider tail = easier/earlier wave catching.
Good luck - let us kow how the experiements go - Taylor
I seem to recall a photo (Surfer’s Journal?) of a big fish that was ridden at Mavericks… 8 foot board perhaps. I think maybe it was Grant Washburn and he said it worked well. Anyone else remember?
In that same article they talk about another shaper in NorCal making shorter boards for Grant Washburn for Mavericks. It helps that he is huge and has incredible paddle speed.

I read somewhere, sometime at some place (actually make that fairly big Pipe if I recall) that Michael Ho was riding a 5’8". Was about 8 to 10 feet if memory serves me correctly. There’s less rail to shift on a shorter board as well.
I think small boards can do wonders in larger waves, but paddling into the wave will be the weak part. I think heavier would also be better. And you better have a strong glass job, or you’ll have a lot of pressure dents on the deck.
I’ve ridden my 6’ 5-fin fish and a 6’ 2" rocketfish in double overhead plus waves. The hard part is catching the wave early enough. Every drop is usally under the lip and in the air. A lot of times I’m standing up in the lip and falling into the pit. If you don’t fall apart when you hit the bottom, you’ll have whole lot of speed. The second, third and subsequent turns become challenging if your board is too wide. In double ups it easier cause you can catch the foam ball before it jacks up again.
Never been to PE, so I can’t say how hard it will be.
