@coluber2001,
when did thy go over completely to catamarans?
Ive reqd that the speed potential of cats , especially those with hydrofoils, is about 4 times the windspeed, so, in a driving gale we could see 70 mph and higher.(Of course , if theres enough fetch, the wave heights would be more limiting)
I have pictures of the Old Gloucestermen boats(which is where it all started as a market race), J boats, 12 meter classes and they all have interesting design features. Cats, however, I dont know. These guys are gonna be on the edge of disaster in high wind races.
Interestingly, the boats all look pretty much the same so its "sailsmanship".
