How about doing some research on these http://www.thesurfboardwarehouse.com...12in-34in.aspx
You could compare the drag with and without. I'd be interested to see if there is a substantial difference

Wouldnt it be more cost effective to just spend the \$12 and compare the drag with and without them yourself to see if there is a substantial difference? Modelling usually isnt the solution to a ten dollar question.

I am open to any ideas, even ones that are not surfing related.

Check out this video on fins. http://www.youtube.com/watch?v=SH2ylhHktcg

Pretty interesting stuff.

Thank you to the guy that put the LAA PDF up! I've been interested in seeing this for a while.

Maybe try to optimize the geometry of the tail of a board for varying speeds. Compare this to the effect that fins play on speeds. You could also do a variable sensitivity analysis between the two.
What changes have the most benefit over the ranges of water velocities that the board sees.
I've always wondered what the benefits were of having a pointed nose on a board... seems like a waste to me other than cosmetics. Any truth to that?
Board thickness vs. width... speed, buoyancy?

A high quality, surfboard-specific, uv catalyst for epoxy, and an epoxy gloss resin are sort of the holy grail right now for me. Anything you can do to get more research in that direction?
