Right Doug - need more parameters; how about...
28-42', 1985 to present, $30,000 to 100,000, full keel, sloop prefered but maybe cutter rig, let's talk mono-hull, single-handed w/modest help from 1st mate, Great Lakes but got to be coastal cruising capable. So there you have it. That can narrow things down a bit maybe. Yes, I want to open that proverbial can of worms and get real opinions from forum people on specific boats (vs. philosophical rants or 'advice' like go read this book...know what I mean.?) If you got a great bluewater cruiser in mind just say it. Your opinion is as valid as the next guy's.
