I use the Rule 1100, but with an lead-acid cell (3,4 amper-hours) in my
folding boats. A folding double holds a lot of water if swamped, even
with a lot of gear and flotation inside.

I have built a watertight reed-switch, which is operated by a magnet
through the deck (canvas or something else). It works also on fiberglass
boats. No need to open the sprayskirt. I cant explain this very well, my
