J-30 ... I must be nuts!
My brother sailed his from Seattle to Juneau, AK. Seems to have stood up well. He had to do a repair on the bulkhead due to leaking chainplates. Watch for deck delamintion (cracking, scratchy sounds - generally fixable) when you walk around. Cockpit being snug makes for easier singlehanding, as does fractional rig. With a roller-furler, you can snuff the jib and easily maintain control & steerageway with the main alone, reefed if needed. Transom-hung rudder w/tiller also KISS-friendly. Resale of known commodity also a factor for later. Sounds pretty good! Buy now!
