The minimum for electric power (not data) is usually #16, not #18. The reason is not current carrying capacity, it's physical strength.

That said, as the boat's owner, you can use whatever you want to. There are no boat wiring police. Just be sure you have overcurrent protection based on the wire size installed at the source of power.
