I would ditch the 27s and replace with two golf carts. I am not aware of anyone making true deep cycle 27s that don’t cost a lot more than GC2s.

We are weekenders with a week out 2 or 3 times per season. I was wondering what I would do for batteries next time around and this discussion has really helped. My boat has room for 3-group 27 house batteries under the V-Berth and a starting battery under the cockpit. Currently the house batteries are "dual purpose" (whatever that means) 85ah each. I'll go to some good deep cycle batteries next. I think I can get some more amp hours and keep them topped up with a 400watt solar array. My goal is to be able to run the refrigerator and autopilot I'm about to install. I'll keep watching this thread but, if anyone has some advice on a good lead acid deep cycle choice, I'd love to hear it!
