On some boats the two "halves" of the 240V 50A split out into two independent 120V circuits/panels on board, and there are no 240V appliances. In that case, you could feed it with two independent 30A 120V cords, or even two 50A 120V cords. The key is that the boat has no need for 240V. It's just convenient to bring the two 120V circuits on board as a single 240V cord/inlet.


Ours is like that.

And the loads are sorta balanced between the two circuits, water heater on one, cooktop on the other, etc. In our case, two ACs, one on each 120V circuit.
