I wish the technology with fuel cells would advance far enough to be
economical to address applications of this nature.

What type of fuel cells are you talking about? The fuels cells most
people refer to convert hydrogen to electricity. But the hydrogen is
either taken on as fuel requiring high pressure tanks and hydrogen
filling stations everywhere, or its created with electricity, and thus
works just like a battery. There are maybe reasons why this works for
cars, but it isn't very practical for boats.
