Another way of demonstrating catsailing would be a video shot from a boat going along with the action. I was in the 2001 corsair Nationals and there was a video made that really demonstrates the racing. Of course the farriers/corsairs are relatively tame compared to a 22 but a 22 can be stable with 3 crew members. Just found out my "perfectcrew" rode her bike into the side of a house...No more sailing for her this year. Getting and keeping a crew for these boats could be a problem. I trained with a guy that made a committment to race with me on my Tornado. After almost a year it was time to go race and his wife said "No". That was it for that season. A crew of three might enable more people to participate. Shared expenses, smaller people would be able to handle the boat together, and and righting one of theSC/ARC22 is not problem with the shroud extenders and the mast base that locks on but if they don't have thiese features I don't know if 2 people will have that easy a time getting one back up.
I think you can get the video off the FCA site.
