I really like the Rhodes 22 (built by General Boats) -- that's what I'd have if I wanted to keep it in a marina. Large comfortable cockpit, plus lots of neat things that make setting off easier for a short handed crew. (in-mast furling, for one) You can add the new gizmos to the older ones. But they don't seem to be as cheap, and they aren't real plentiful. Being built in NC I bet they're even harder to find on the West Coast. I love my Venture 17 (MacGregor) The 21 and 22 foot versions are a lot of boat for hardly any money. They tow easily too. You didn't say what sort of vehicle you're going to be towing with. The Venture 21 could be towed with a transverse engine V6 car/crossover. The Rhodes you'd probably want a pickup truck or SUV to tow it any distance.
Keep the expenses low and the good times high.
