My boat has non-standard color coding on the AC wiring, typically all
3 wires red instead of the US standard of black, white, green.

Identifying the hot wire is easy but I'm not sure how to positively
identify the neutral wire vs the safety ground. Measuring voltage
from the hot wire yields 110 to either one. This is looking from the
load end not the panel end of course.

Anyone have suggestions?

Neutral and Ground should not be connected on-board. (although if the
boat is wired with all red wires, there's no telling what strange
things may be going on...)

Disconnect the boat from shore power, and use an ohmmeter to check for
continuity between the Ground pin on the shore power cable and the
unknown wires. (If the boat has an inverter, make certain that it is
disabled while doing _any_ work on the 120VAC system!)
