Hi there, wondering if someone can give me some advise on this. Will I get away with a Drops GraphiteTec 37 size fine on my Star-board 145, 03 model.(77.5cm wide). I want to use it with a 6.5mt sail in heavier conditions, 20-25knots. I've tried a 32 fin in the past and not had a great deal of luck getting going. I normally use a 48 fin but have a hell of a time keeping the board on the water with this fin and the 6.5 sail on 20knot+ days. Any advise would be greatly appreciated. cheers, Ads
