When moored to a shore installation or to a tender did an Elco boat receive electrical power from the shore or tender, saving the boat's generator?

If so, where was the connection made?

Thank you!

Jeff

As far as location goes, the Elco drawings are spotty regarding shore power. This is what I was able to dig up:

The location for PT 103-114 at bulkhead 47, a few feet forward of the aft end of the day cabin:



The deck plug for PT 103-196:



The connection instructions for PT 565-624:



This looks like the (covered) plug, on PT 613:

Jeff;
Hmm, to me that looks like it might be a fresh water fill for tank below decks. being that this is a later series boat, could it be somewhere else? My personal experience, we always had Shore Power connections mounted to a vertical bulkhead type surface above decks, as the cables usually ran down the bulkhead to below decks.

While we have this photo up, what is that "cable connection" coming up through the deck next to the torpedo rack? were these later modified with electric release motor?

Take care,
TED

You're welcome Jeff.

I dunno Ted, it's in about the same location as shown in the 103-114 drawing but that don't mean it's a deck plate for shore power hookup. None of the deck arrangement drawings list it, or any water fills.

I've no clue as to what that cable going to the rack is. It goes into a device on the rack:

I did some digging Ted, PT 565-624 did indeed move the potable water fill but it was from the chart room floor to the bridge deck just aft of the chart house. The 3 fresh water tanks for the engine cooling system were small and part of a closed system like a cars. The engine plumbing system drawings don't show any deck fills. I'd guess the photo shows the deck plate for shore power hookup.

It looks like it is a hydraulic line Ted, for remote launching:

No I think it is a pushbutton operated solenoid release to launch the torpedo. The pushbuttons to launch the torpedo were mounted near the helm. The 24vdc cable leads to a plug on the deck and can be disconnected. I believe that the hydraulic thing not invented until post war. Jerry

That's a post war (1952 I think) photo of a boat sent to Korea Jerry, so that would line up with what you say.

Here's a closeup of the hydraulic ram from the patent, looks like a dead ringer for what's seen in the photo:
