Wow, I've been able to access this newsgroup 2 days in a row!

The open circuit is a dead giveaway. Almost certainly the plug has become
disconnected or if no plug, there is no connection to the sensor.
Unfortunately, it appears that you will not be able to investigate until
the boat is pulled. Even more unfortunately, if your climate is anything
like ours, that won't be very long from now...

Sometimes if you can convene a gathering up on the bow, you can get the
stern up to where you can work on it. Maybe from n a dinghy if not from
the boat.

Send a few of the heavier crew members up to the fo'c'sle:

Another method is to pull the bow down against an anchoring clump or
something similar to raise the stern.
