If the shore breaker trips, you have a wiring problem in the 30 - 15
amp adaptor, the dock outlet (unlikely) or on the boat (also unlikely,
if things worked when plugged into a 30 amp outlet.)

WE DID TURN EVERYTHING OFF AND PLUGGED IN AND TRIPPED THE BREAKER ON THE DOCK.

Here's a lifeline: if you blow a shore supply breaker when your stuff
is all OFF, you have the famous "American Neutral to Ground" connection.

I've found it impossible to respond to the posts with much of that
shouting, but a test I'd like to see is what happens if the cord isn't
plugged into the boat, but both pigtails on shore (if I'm reading
things correctly) are. If that trips the breaker, the problem is one of
the outlets OR the pigtail itself, nothing on the boat.

If the breaker trips only when plugged into the boat AND the boat's
breaker doesn't trip, I'd carefully examine from the plug to the
distribution panel for a shorted wire. The receptacle is the most
likely culprit, but there could be chafing down below.

I'd also test to see if another boat successfully plugged in elsewhere
could draw from his.
