That would be the next test, connect the
inverter directly to a 12 volt
boat or car
battery. There's no telling how much voltage drop there is in the
wiring to your boat's 12 volt outlet.
What I'm not reading in your post is any mention of overcurrent protection. We can assume that there is a fuse or circuit breaker protecting the
wiring to the 12 volt outlet but if you're going to wire this inverter to the battery, the wiring will need an appropriate sized fuse or circuit breaker within 7 inches of the source of
power.
Because the resistance of the conductors matters more at 12 volts than at 120 volts, your best plan is to keep the 12 volt wiring as short as possible and extend the 120 volt wiring to where the crockpot or other load will be.
