Subject: Looking for battery/electrical ideas

+1 for small motor cycle battery, ours dates 1999 and is still kicking so we haven't found a need to replace it. All we run off of it is LED lights, Navman depth/speed and occasionally GPS.

Around the buoys we don't even need the battery as we use a RockBox for a compass. However with the water levels the Great Lakes are experiencing we'll probably want to have our depth running.
