whats your sail no? where are you based..
3.7 179 Blood Vessel. in rotorua the foam is actually a jandle jut up that when the center board is raked(?) back it doesn't cut the hull open.
i put some foam type stuff down there, soon see how it works, without it it was just putting small dents in the trailing edge of the boat, and also in the bottom and top of the case...
are you going to the sprints down there on the 15/16th?
also, are you selling that enclosed road trailer? if so i will pm you...
