I think the Moth can work as a One Design, just put it to tender and select a builder for a set period.

49er, perfect. for both Men and Women (maybe a smaller rig for the girls)

RSX... jury is still out on the RSX, maybe another trial to select suitable equipment?

Kite... I'm just not sure what the event is meant to be, is it racing or doing tricks?

Supercat 22, ummm.... I really dont understand this one at all! Its not OD, not modern at all, and freaking massive for 2 Women!
