Look at the current draw. Even a small micro way will require more current than a small boat can easily provide. Almost all compact microwaves call for a 15A circuit. Even if you can get away with 10A, that's 10A at 120V, or 1200W. In other words, the draw on your boat's batteries would be about 100A at 12.5V. On big boats, with big battery banks and gensets, that's doable. On a 27-foot boat, not likely.
