Gimballed..15 or 30 degrees?

Be carefull with an engle, make sure you hear the one you want to buy running, mine must be a dud as it vibrates very badly. I've got to take in back and see if they can fix it...

My old Ingrid 38 flew like spit at 18 degrees with one reef in the main, full stays'l and cutaway forefoot working jib in about 25 knots of wind closehauled. Occasional puff above that would put the rail under and just over 20 degrees as I recall. The kids were constantly screaming, 'put the rail under again, Dad'!
I'd go with 30 degrees unless you plan on sailing on a lake somewhere. Any coastal passagemaking or offshore sailing you are bound to hit some weather and if you want a hot meal, you will need a properly fitted stove to produce it.
Good question! Phil
