point of stability of say 110 degrees is more likely to stay upright than a
multi-hull where the vanishing point is more like 70 degrees.
Hey, Mike, what's the source for that data or is it conjecture?
I'm on the hunt for news of any power catamaran ever capsizing--and
so far I've come up empty.

Excellent point. There is some conjecture concerning the likelihood of
overturning. The point of vanishing stability is not conjecture, but the
actual numbers will be more or less than the ones I mentioned.
As for a powered catamaran ever capsizing, I got some email the other day
which I can't find at the moment, which may be a lead to such an accident.
But what may be more to the point is that a powered catamaran is less
likely to go over than a sail one as there is no sail up in the wind. On
that note, I recall the message I got had to do with a cat(sail or power?)
overturning due to wind getting under it and flipping it.
Since it has been about 2 weeks since this was posted, you may assume that
I am back in my cage.
