Jerry,
By all means, trapping on a catamaran is much easier. Although we're stereotyped as being unstable, cats are a kazillion times more stable than monohulls (just try to step on one from a dock and you'll come to a full understanding). We just load up the boat with more horsepower to compensate! Seriously though, we usually trapeze much lower on catamarans than monohullers do because of the additional stability.
