Been a monohull guy all my life for no particular reason. Am very enamored with the idea of a trimaran (like Corsair 27). Any big differences in sailing one? Am not a racer so figured we'd stay reefed until we figure it out.
I suggest joining the Yahoo Farrier group and, if possible, sailing on one. You're going to get a lot of misinformation here. You will also need to be pretty specific; there are trimarans, and there are trimarans. If you mean Farrier designs:
* Keep it light. But you can cruise them if you keep the junk out.
* There is less room below but more room on deck.
* With the wide tramps, it's pretty hard to fall off. Really hard.
* Very shallow draft with the boards up, but to sail they draw 5-6 feet. Since that is a dagger board, that can be damaged by high speed groundings, you don't sail fast in thin water.
* They point and tack very much like monos. In fact, while tacking there is only one hull in the water, so that should be sort of obvious. They tack nothing like Hobie cats. The are easy and fun to tack.
* They are faster if you push. Most owners will see 12-15 knots off the wind regularly, and some faster. To windward they are only a little faster.
* They are performance boats, not cruising slugs. You will either reef or bring your A-game. If reefed they are pretty calm, and you don't reef that early.
* The motion is quicker. Some like it, some don't.
* They heel more than cats and less than monos. Obviously.
