Dave, Marty here, I measured that starboard carve fin you thought you could put to use which we talked about on tuesday. Its a 42cm wave fin with two mounting bolts. Any good to you?
I am speaking from my own 95kg belly ballast perspective here Dave - It comes in useful to hold onto the 6.4 when everyone is scrambling for their 4.7's and you can't be bothered changing down!
