I used diverted power from my solar regulator to run fans throughout the
boat.

I like the idea of diverting to the water heater, but most of us do not
have the option to add a second 12V element to our existing heaters.

One thought, would be to add a second heater in an external loop around
the water heater - something like the add-on heaters that are sold for
cars in lieu of a block heater. This site has the elements:

But, if the solar panels put out, say 150 watts for 8 hours, what
happens when the water becomes too hot? With a small boat type water
heater say 6 or 10 gal, this could happen quite quickly. Maybe then we
throw the towel?

You can get elements that have both 120V AC and 12V DC feeds. See
