I know it's theoretically better to keep batteries on a

the boat and stored by the yard. (Nevermind the reasons
why I don't
want to take them out myself and home to my basement.)

I would vote in the "no-problem" camp. The self discharge
rate of
AGM's is very low, and in the winter temps should be a
quarter of the
summer rate, or less. If you're able to visit the boat a
few times,
you should check the voltage to make sure nothing as gone
awry. And a
small solar panel might not be a bad investment
In my case, I have a solar panels (150W) under the
shrinkwrap that
keeps a small charge on the large flooded house bank. The
AGM starter
bats (Optima red top) can fend for themselves.
*Under* the shrink wrap? I though solar panels had to get
direct sunlight.
