Interesting Question - If so - they were most likely origional 14 sail #'s, and very old at that, so there should not be a conflict when regatta-ing.

Typically, if there is a conflict however, the person with the origional # gets to keep it and the other person would duck tape a large 1 or X or something at the beginning or end of the sail #.

Had to work (Damm!) and not in CA.
Go 204 teams in CA!!!!!!!!!!!!!!!!
