For a main AC switch the hot and neutral are both opened. That way it there is a reverse polarity issue in the marina you can be assured that there are no hot wires. The individual circuits are single pole, opening the hot wire only on most boats. I say most because a friend has a French built Beneteau CC36 that uses double pole breakers for every AC circuit.

On a metal boat double pole switches are often used for all circuits, AC and DC, so when it is off it is guaranteed, for stray current reasons.
