There is some good info above, esp. Ex-Calif. I wont repeat any of it, suffice to say, if we go past 12 deg. we shorten sail, we CAN beam riach with everything up in 20 knots, do about 8, heel about 20, reduce sail, drop to 7 still fine speed, but you can live like civilized people inside, with 10 deg heel.
I must disagree with the wide transom comment above. Yes, at anchor
, or in a beat, but when you are running in 30-40 ft seas that wide transom is an adrenaline trip! I have a windsurfer, surfboard, and kite rig for that.
There is a little clip of Gilana sailing in the Azores
in 20kts with seriously shortened sail, but look how comfortable she is. Yes we could have flown more, but then we would have heeled too much for comfort.
you know, when we started sailing we wanted the rail in the water
, but that was just what we saw and heard about. Our first lesson came when we were going to arrive too early after a crossing, and we shortened sail, damn if the boat did not flatten out and accelerate. We like the Ketch
rig for many reasons, Air draft
, low center of effort, more options, etc.
Our boom is low and the boat is flush deck
, so you have to mind your head
, but hey, we sit most of the time. Look out for these apartment building centre cockpit bimini
on top where the boom is way high. Some newer Catamarans have a flybridge! The boom is about 4 metres above water
Click on our web page link and then the button called "The Boat" you will find the clip I mentioned there.
In short, heeling is not the answer, balance is. You want the keel as vertical as possible. There is a great resource on the web about sail trim, here, Relocate
The thing about a cruising boat is that you must trim to take a huge amount of air and change its direction "just a little" and that converts to thrust, once the air spills off the sail at 25deg, and the water spills off the keel, you might look great for a magazine cover, but that is all. Of course this only counts for a heavy displacement
boat, once you start talking about sleds that can sail faster than the wind
its a different theory.
Shortcut for you, if you want to go fast and not heel, get a catamaran
