You may need to reset a GFCI receptacle.

 

Thanks. I checked the GFCI outlet that is mounted on the cabinet where the sink, fridge and microwave are located and it has power.

 

You got something serious wrong if that AC Volt meter is correct…it’s pegged above 150V. Unplug that now before something gets damaged.

Where what and how are you connected??!!

 

Almost looks like the boat is across the two hot legs of the dock 240 volt supply. That would illuminate the reverse polarity light and peg the volt meter.
I'd get it off dock power right away.

 

If you put 240vac into your 120vac shower power it would kill your charger ac pump and just about everything, that would explain the bright ac lamp the reverse polarity and pegged ac volts gage. Unplug immediately. They make it pretty hard to do this, post a pic of your power post and cable.

2 Photos of cable. Note, the led is not lighting up which is supposed to indicate power in the line.

Sounds like the marina might owe you some new appliances.

 

This is what happens if a 30 amp 110v plug finds its way into a 220v outlet.
