I think I finally get the picture, and I don't like what I see. ISAF should not allow a minimum crew weight limit for the Tornado, because it would be potentially discriminatory in terms of gender, age, size, and ethnic origin. This is supposedly an "open" class.

I do hope that there is a rule that prevents teams from campaigning for four years or two years or whatever toward the Olympics and then winning their national trials and then, based upon the advance weather report for the Olympic venue, dropping one team member and replacing with either a light person or a heavy person, depending on the forecast. THAT would not be fair.

If there are special circumstances where a crew member can be replaced at that point (like death), they should have to replace the team member with someone of basically the same weight as the person being replaced.
