I did look into adding a second power inlet receptacle at the bow at one point but a number of technical issues made me rethink this idea. One is that you need to have a breaker within 10 feet of the receptacle. I did not want to have such a device in the v-berth. Also, in my case I wanted to keep the original outlet at the stern, which meant I would have had to add a transfer switch at the main panel. Otherwise, since both circuits are wired together in parallel, hooking up one would make the other power receptacle "live"; i.e. the exposed pins would be live. So I ended up just getting a second 50' extension cord. Solved all the issues except for the extra labour whenever you need both extensions.

10.2.6 Individual circuits shall not be capable of being energized
by more than one source of electrical power at a time,
and each shore power inlet

10.9.2.1* If the location of the main feeder supply disconnect
circuit breaker is in excess of 10 ft (3 m) from the shore power
inlet or the electrical attachment point of a permanently installed
shore power cord, additional fuses or circuit breakers
shall be provided within 10 ft (3 m) of the inlet or attachment
point to the electrical system of the boat.

We installed a 30 amp shore power connector in the bow this last winter. The project was not too bad to complete and does make it easier as we bow into our slip and reduces the amount of shore power cable to deal with.

We used Blue Seas systems components to do the job. You need to have a 30 amp breaker within 10' of the connector in the anchor locker. We did the 30 amp connector on the port side of the locker.

The breaker was installed just above the shelf on the port side of the interior panel.

The transfer switch for the bow/stern was installed under the nav table and prevents either end being energized at the same time due to a saftey slider.

Our boat is a 2006 and has a galvanic isolater at the stern. It is necessary for the ground to be connected with the bow inlet as well to provide protection to both.

We are really enjoying the ability to get shore power from either end of the boat.

Cheers,
