The Freezer on the Athena 38 (worst charter boat ever) has been dodgy for a long time. Boots the mechanic can't seem to find the leak and just comes to charge it every couple days. But my info could be old.
But I will say, NO one can clean a boat like Brent does and when it breaks down (not if) he will race out and and throw money at you to keep you happy.
His boats are more like your boat at home, they all have issues and you pay less and deal with issues. You can pay more and have less risk of issues. Just depends on your budget. But personally I would pay more to just not deal with Brents very odd personality.
