Sanding sharp trailing edge of fins

[oldmansurfer]

I think those would be good for most surfers but the elite surfers would probably prefer knife edge fins due to less drag

I'll check it out. As far as the whale tubercules go, I'm intrigued. I've always wanted a cerrated fin that would allow me to improve my surfing performance and saw logs after my session.

Roy Stuart himself actually made (makes?) some of these. I bought a set a few years ago but snapped one of the fins after about 5 sessions (my fault) and didnt replace it. Have to say I didnt really notice much of a difference, if anything they werent as good as my normal fins. I think perhaps they were a trifle large for my board - so not the fin shape per se, just the wrong fins

anyway, you can read up on them and Roy's philosophy

See what you think.

Ouch, back in the day people used to sand the leading edge of fins, and a very sharp trail edges , instead of plugs for leashes a hole at the base of the fin. stab and slash wounds all round , heal quickly and well!

Stitches or did you just glue & tape that up?
