We are in the process of rehabbing a old Catalina 25. It has shore power set up with all wiring and receptacles in the boat typical quality to what you would see in a house (romex wiring, metal junction boxes).

However, in the aft cabin, and bow cabin there is a gold colored metal tube about 3' long, snapped into some clips on the wall (so it can be snapped on/off the wall easily), with a cheap lamp cord type 2-conductor wire leading from the tube to a typical 2-prong plug. The cord is just long enough to plug into the closest 120v shore power outlet. The other end of the tube is sealed with metal cap.

Any one have any idea what these are?

The way the tubing is sealed and finished looks professionally done. But the rest of the shore power system has a ground, unlike these tube things which do not have a 2 prong plug.

 On the back of some piano's are a similar sounding device, they are dehumidifiers for the internal workings of the piano. Perhaps a PO installed them for that purpose.

I recall said devices while I was a music major in college. Maybe someone was storing a cello down there.

These are heat rods to plug in to prevent freezing in the cold winter temps. I used one in my diesel engine compartment on my previous boat. Works great.

Thanks, one more mystery solved. However, not sure if I trust a bare metal electric heater against fiberglass, and down here freezing is not a problem 99.99% of the time, so if anyone wants em, let me know.

It sounds like a Goldenrod heater. It operates at a low enough temp to not be a risk and can be used as a dehumidifier by warming the air and thereby lowering the relative humidity, also not so useful in warm climates.
