Wouter,
That suggestion would make multihull sailors happy, but apparently not any of the women sailors. If no women are interested in sailing Olympic multihulls (as they have expressed at the meeting), do you really think that just having the equipment approved is going to change that? I guess anything is possible, but you know the old saying, you can lead a horse to water, but you can't make it drink...
Other than continental championships and Worlds, where women (who normally crew for men the rest of the year) tend to hook up to sail together for a short event, where are the women multihull teams in the world racing today, even at a non-Olympic level? I think I can count female multihull teams on two hands in the US.
Personally, I think the way to solve this (lack of female participation in multihulls) is forced mixed doubles, on something other than the Tornado. Not saying the Tornado can't stay for men (or call it open), but add a mixed doubles multihull. For that matter, any of the two-handed boats can be changed to mixed doubles.
