I just want to make sure, Bert:

Are YOU making sure that the N20 and the F18 NACRA, both of whom have non-stock sails...

both their results AND the fact their sails are aftermarket are indeed duly reported to the Portsmouth Committee? From the results posted it appears you did indeed mention the N20, but the NF18 is not noted.

Regardless of your opinion, Portsmouth is clear in that a non-FACTORY sail, regardless of size differential, immediately takes a hit. Should the size be larger, it then takes another.

You may cry 'unfair' all you want but the rationale is that if the boat owner isn't trying to advantage with his aftermarket sail then he wouldn't bother with one, so the burden is on him and he takes a hit.
