Toss the rule out? I dont think so, if they dumped a safety rule, they would loose a lot of credibility.

Liability? Wouldn't that cut both ways, if more people died while trapped (pun unintended) in their harnesses? I dont know, but wouldn't suing ISAF over this be a quick way to kill off their own business, instead of changing their product?

As long as they dont go so far as to only allow certain brands, I dont see how they could be sued over this? The ITA only allows certain sailcloths, spesific weights and brands, as far as I know nobody has sued them over this yet.

Those among us who race, needs rules to do so in an orderly way, isn't that legislation?

I am neither a lawyer or businessman, so I dont know..
