Terry, we have2 group 31s and rage refrigerator and a few lights give a load of 6+ amps, a short motor run I don't feel is enough charge to sublime the 110 amps usable for a night on the hook and the next day. We are coastal sailors and will rarely be out two nights. I prefer Sailing bar to bar over long voyages.
The space under the port settee is pretty full , a starting battery, two 31 and a battery charger unit. Might could squeeze in one more 31 but would like to have four. Total. Hunter decided this area into three compartments.
