Do you have 30 amp service at your dock ? If so, one of these is the easiest and quickest way of getting power to your boat. Several smaller cuddy's use this at our marina. 30 amp to 15 amp shore power with receptacles for 3 tools and is GFCI protected. Then just run an extension cord into the boat when you need A/C power for TV, coffee maker, etc.
The "factory" way is much more involved, and more expensive. At minimum you will need:
Shore Power inlet - located within 10ft of breaker panel
Galvanic isolator - to protect against stray currents
AC breaker panel - Used to distributes the AC power
Outlets in cabin - GFCI receptacle are best
You will need to follow ABYC standards if you go this way, use only marine grade wire and breakers etc.
Good Luck, and be very careful if you go this way. If it was me, I would leave this method to a professional installer, too much risk involved if you miss a step, or forget to follow the required standards.
