    Believe it or not, I have actually seen shore power connections on some
    Bayliner style boats installed in the topsides of the hull BELOW the rail.

    As described in the below email, I too hard-connect (soldered-on eye
    terminals bolted together with 1/4-20 ss machine screws and rubber hose
    slipped over the connections) my shore power cable (3x#6 SO cord) to
    identical line going to the ac distribution panel. This connection is made
    in a well-protected part of the boat and I have never had trouble with it.
    I have 50 A breakers on this line, mostly to turn it off and on.

    For the other end of the shore cable I have a "range plug" as used for
    shoreside electric cooking ranges. I then have a number of short adapter
    cables, each with a range receptacle on one end and whatever plug is
    required on the other. Since the only places I have plugged my shore cable
    into in ten years have been boat yards I have used only the un-adapted
    range plug (very popular with commercial folks) and in the case of the yard
    we use in Gloucester, a commercial welder plug (which looks like a giant
    version of the standard household plug).

    Putting hands on machinery to check temperature is a standard big-ship
    practice. A quick light touch at first, then more contact as you become
    more confident that you won't get burned. If you can keep your hand on it
    is us usually OK, except for electrical wires and plugs, etc, which should
    not be more than just warm unless designed for higher temps.
