110 to shorepower conversion?
Take a look at page 626 of the West Marine 2002 Master Catalog. There''s an excellent description of the various types of connectors. Nearly every marina and boat of this size that I''ve seen uses a 30 amp 110 volt twist lock connector -- female at the dock and on the boat (sources of power are always female to prevent exposed pins from being hot). Larger boats might be 50 amps or 220 volts. Confirm your plug by looking at page 626.
Then turn to page 630 of the same catalog, it appears that you want is West Marine 194423, Marinco 104A which has a standard 3 prong male plug on one end and a female 30A twist lock on the other. They also have a 264598 (Marinco 106) which is 20 amps and appears to somehow locks. I''m not sure how as the plug configuration appears to still be a standard wall plug. The latter is a lot more money, I doubt if you need. You can call West at 1-800-BOATING, their technical support is pretty good and they should be able to confirm what you need.
I''ve used one of these pigtail adapters on my boat and it works fine. If you have a polarity reversed light on your a.c. circuit breaker panel on your boat be sure to check it after you plug in to make sure everything is OK. Otherwise you could get a shock from touching the prop shaft or other supposedly grounded items. A surprising number of marinas and 110 volt plugs are miswired. I didn''t connect the available power directly to my boat last winter because the light came on indicating reversed polarity.
