S2 7.9 Meter Class Association

I plan on replacing my propeller and since I don't race any longer and have considerable barnacle buildup during the season (even with monthly diver cleaning) I'm wondering whether to stay with a two blade f martec folder or consider something else Any suggestions? Thanks

After being grounded while trying to back into a marina slip,I now cannot raise the board as it is wedged at the leading edge and forward starboard side of board.(the board can only come up 6-8inches from fully down before it binds. Was going to have yard try to pull board aft with lines on a cherry...

Are there any specific different recommendations for inboards concerning mast tuning,setup or sail trim to increase boat performance? Thanks Bob Wi.lliams #497
