I'm working on a college engineering project involving surfboard fin design, and have a brief survey to gather research. I wasn't completely sure if things like this were allowed here, but I saw the post about the kickstarter, so forgive me if this isn't permitted.
The survey takes less than five minutes, and filling it out would really help us!https://docs.google.com/forms/d/1A3rr1WyUZv5ephpsQUqJr7W6UiP5dpl4S7pE2WR...
Years ago my buddy Pedro was experimenting with fins and made his twin fins so that the outside fin would bend or curve around in line with the water flow during a turn and the inside one would remain fixed to pivot and drive from. Basically the back two thirds of the outside fin would flex/bend and curve in towards the stringer, but not be able to flex outwards. It made the twinny too loose and bigger fins were needed. They worked but I can't recall the details. He was definitely onto something. It would be interesting to see that concept developed and applied to thrusters and quads.
Quick and easy jt
Thanks for the responses so far guys, I was surprised at how many people filled it out. Hoping to get a few more!
jt...what university do you attend?
