I have chartered ChaCha twice. Last time was last March. Time before that was two years ago. For us the boat was fine. We're not fussy though. I will say that I did notice a decline in its condition by the second time we chartered. Mostly cosmetic stuff on the inside. The bottom looked like a hay field. I assume it's been cleaned and/or painted by now. One other thing that bothered me a bit was that the boat seemed to list to one side at anchor. Not sure why. It was enough I could feel myself wanting to roll to one side while I slept. Weird. The rigging and sails were good. Motor ran well. Never had issues with battery charging. One thing I wish it had was light in the cockpit. I would consider bringing a battery operated light next time. It would make sitting out in the evening a little nicer.
Anyway regardless you can't beat the price Brent charges. We would charter again just for that reason. Pm me if you want more info.
