Monohulls point higher feel more like a sailing boat ie. In a catamaran due to their lighter weight you carve through the tack rather than making a sharp directional turn as you would in a monohull. Although the rule is that multihulls are faster which makes for shorter passages and gives more chance of outrunning bad weather there are monohulls that can do the same.
Overload a powercat and most of its advantages disappear as the twin hulls sink deeper into the water and the top of the tunnel begins slamming into waves. They also offer safer anchorage and are easy to control. The main characteristic of sailing boats is the stability.
The windier it gets for a given amount of sail the more they heel over and are the traditional choice. For these reasons of feel monohulls tend to be the best boats on which to learn. Because of how monohulls are shaped they dont suffer from water slapping against a flat hull.
They cut through the water which allows for a quieter sailing experience overall. This may sometimes feel as though the boat is getting beaten to pieces. Lets face it many are downright ugly.
