"Shore Power"is a fancy term for AC electrical power that comes from "the shore", as opposed to electrical power that you generate yourself.The first question is, "What is on the boat that you want to run with 110 volt AC power, and how much current does it require?" To be safe you will need a fuse or breaker box between the appliance/light and the power source ... and wiring that is the proper size or gauge."Shore Power" is usually provided at a marina in the form of a heavy duty, three pronged, twist lock, waterproof, extension cord. The female plug with power connects to a male deck or hull fitting in your boat, that in turn connects to your breaker box, which connects to your outlets, where you plug in your appliances.Please resist the temptation to run to your local hardware store for components. Bilge water is VERY hard on electrical connectors and switches.Check with the marina you want to use to find out the EXACT type of plug they have so you can get a proper fit on your outlet. There are several different manufacturers who make "shore power" connectors. Westmarine.com as well as many others, sell these fixtures.More Power to Ya,Ol' Dave
