Used it loads on skiffs in the past, bloody great stuff. Whether its needed for wsurfers I don't know but could be worth a try. I think the windsurf place in WA sent round an email saying they had stock of it.
my race sails do rotate fine in order to help the cams along, i put McLube on the inside of the cams C <- ONLY as someone said - NO good on boom area !!!! also found not good to put on mast directly since not all my cambered sails have the large luff and pop cams on later - some need to pop on first while sliding mast in and these may slide off if McLube was on the mast directly
Bruce Peterson of Sailworks swears by the stuff
it is a very good water resistant lubricant - too good ?? use with caution !!
We used to pour a couple of gallons into the ballast tanks on racing yachts while on the hard stand and pump it from side to side to lube the ball valves then empty it back into a holding drum to use it next time. Good stuff.
