I own a 2006 Majnship 34T, twin 240 Yanmars, bow thruster, genny and (2) A/C units. Only had it a few months. We love the boat. If I cruise @ 12 knts she burns 10 GPH. Slow down to 8 knts. she burns 6 GPH. Great engine access. I can run the genny underway and have the A/C running. (important in Fl). I just hauled it out for a bottom job and maintenance. No complaints so far. It's a BIG 34. Perfect 6,4,2 boat. ^ for cocktails, 4 for dinner, 2 for overnight. We have had guests overnight, they have to be very good friends. Gets tight. There are plenty out there. If you see a real good deal, be cautious. The price is pretty much set because they are very popular and the brokers know what they are worth. I bought mine 220 miles away and took it home on her hull. I would have no problem buying a Mainship anywhere and trucking it. Just get a survey, plus I had the engine oil analyzed.
Good luck. Nice boat!
