Mark,

Assuming that you are referring to the larger sail plan available for heavier crews under F18, I think this boat should be required to carry the additional corrector weights in order to reach the minimum crew weight for the larger F18 sail plan...as I think would be the case in the F18 rules. This move by the Portsmouth committee indicates that they now consider the Tiger as an F18 (which should be the case) and no longer recognize an individual Tiger rating.
