What size patches for glass on quad fins?

Hi all, I have tried searching and watching lots of vids but cant get a definitive answer. When doing glass on quad fins should the cloth patch wrap the rail or not? I’m doing 2 layers of 60z on each side of the fin so should one layer wrap the rail and the other not? Many thanks.

Hey Soda bread,

None of the patches should lap the rail. I am assuming that there is a hard edge in the tail of your board where the fins are. Put a piece of tape along that hard edge hanging down towards the deck. The patches will probably overhang the rail a little bit. After you laminate the patches to the fins and they are about 3/4 of the way cured, run a razor along the top of that tape line to cut the piece of the patch that overhangs. That is what I do anyway. Good luck!

Perfect thanks!
