to gbleck: we all know that the IKA rule about board appendages DO exclude foilboards, because foilboards with a max. Tbar length of 50cm simply wont work properly. Foilboards need at least 80cm. The best foilboarders ride with a Tbar length between 90 and 100 cm.
True, but this rule can be modified by the race committee. I have seen it done before, even under the IKA umbrella. So it is up to the riders to convince the race committee to modify this rule.
