One of my favorite science-fictions was imagining the Sea Slice, repurposed as a deployable floating mini-solar power plant. To actually be able to get anywhere, you'd need a gobsmackingly large amount of power storage, or you just take it day by day, charge for a couple hours, go, charge for a couple hours, go.

Sure wish I had a million dollars sitting around when the ship went on sale for $280k. And a couple more friends with free time & well-equipped workshops.

When you're docked in a marina or similar its unlikely there would be space. When you're sailing or motoring somewhere you want the minimum drag\resistance through the water, and more importantly, the waves would smash them to pieces in no time. To make them weatherproof would mean making them less like a floating solar panel and more like a small boat.
