Interesting...
My boat actually has a lip that goes around the top and the bottom of the daggerboard wells. It is about a 1/4" thick and about 1" tall (as tall as the carpet). This is not a fairing, the carpet edges are still exposed (and there is still some slop to the board) so I don't think it was added by a previous owner. For reference, my boat is a '99. maybe they changed the cases after that.
Just thought I would share what I have seen...
cheers.
Maybe that was what was left after all the gel coat was taken off the boat... <img src="http://www.catsailor.com/forums/images/graemlins/laugh.gif" alt="" />
