Most boats in the South have air cond aboard.
As more than one unit is usually required a 30A120v power hose is usually too small, tho a boosting inverter will help start #2 air cond..
The ancient 120V 50A plugs and wiring is long gone from most marinas.
So 2 legs of 120V are usually brought aboard , called 240V in most areas , even tho few boats actually USE it as 240V.
Northern boats that operate all winter will usually have a furnace of some type.
The use of 120v electric is a waste of effort ( 30A is only about 12,000btu)and 240V resistance heat would pay for a furnace in a short time if on metered electric.
Boats travel,so electric setups does vary , ours has an installed Dickinson range for heat .
And a 15A extension cord to power something should we be dockside , NO installed AC electric system at all, as none is needed.
