Adding shore power outlet

[dlochner]

2 galvanic isolators are not necessary if the shore power grounds are joined at the shore side of the GI as they should be.

You're correct, you don't need two. However, the installation will be easier if the GI is located near the ELCI and inlet than splicing wire and running it aft to the other inlet.

if there isn't a shorter way to run the shore power cord, then a 25' extension cord will be the easiest and least expensive option.

Agreed. If the OP is committed to a second inlet, it might well be easier and cheaper to add a second GI than pulling an extra ground the entire length of the boat.

A rational person would total up the bill of materials to do a proper installation that the insurance company won't give stinkeye over (second ELCI, second GI, transfer switch and cabling) factor in time to install it, then head online and get an extension cable coming.

We're not always rational about our boats though.

Stern in would be easier for shore power but privacy would be sacrificed with all the people walking the docks and the challenge faced backing a sailboat into a slip in a narrow fairway under windy conditions..
