Help at sea

Bulkhead · 10-28-07, 10:43 AM

Hi.

Is there any way to call for help out in the open sea?

The reason is the "diesel and batteries" post i posted 5 mins ago

No help at sea. You are on your own. Use your resources wisely

the last time this happened to me i determiend that even with the batteries pretty much completely dead the ship would at least make one knot.

problem is that i was about 800nm from the nearest friendly port and that it would have taken me a life time to "drift" back to base.

another similar problem i encountered once was the loss of my rudder! i was pointed at Japan with no way to steer!

this post shows how there are two additional arguments for simulating the ability to turn using one engine... as well as run on the electric motors while surfaced!

also one question... surely there was a generator like mechanism that would recharge the batteries when the engines were not able to run.

How? A generator is a fuel-powered engine. Where would you have room to carry it? The batteries on a submarine are huge, and take a lot of charging. Battleships have auxiliary generators, but they're bigger than a sub is wide.

Basically, any auxiliary engine powerful enough to charge the batteries would be powerful enough to drive the sub. You'd be better off trying to rig a sail.

your right... i didnt considerthe mass assoiciated with such a machine.

but i still think we should be able to use the engines differentially and that we should be able to use the Electric motors on the surface.

Oh, absolutely, I agree with both. Not being able to turn the boat around and head for home is ridiculous, and running 'decks awash' should always be done on electrics, not to mention pulling away from and into the pier at home.

Too bad we can't call for a tow...

Some fleet boats had aux engines capable of driving the sub at 5 knots while charging batteries and maintaining electrical systems and air charge. The Gunnel lost all four engines one at a time on returning to England in Nov of '42 and relied on the aux almost the whole trip back.

You can simulate calling for a tow or fuel supply drop with a bit of fancy 'Notepad' footwork; save the file, then edit the settings so that you are on unlimited fuel (or whatever setting you need), load it up and then off you go, edit them back to limited fuel after you are home.

A tug mod maybe?

I dont think the modders would waste time on a mod like that...

My point is that it would be nice to try all possible way to get back home, thats what they would do in real i belive.. one way is to go at 1 knot on the batteries

Torplexed · 10-28-07, 12:57 PM

Depends on where you are, but at one knot you're gonna be easy prey. A boat stuck deep in enemy waters would probably try to call up another fleet boat to help with repairs. Failing that the other boat would take off the crew and try and scuttle the disabled boat as in the Darter and Dace situation. Failing that the boat would certainly be scuttled to prevent it from falling into enemy hands and the crew would try to make for nearby land as best they could.

Well, I could be wrong.

I would substitute 'all' for 'some' in your description, because they probably all had those auxiliaries. Five knots is a slow voyage, but if they figured out how to do it, why shouldn't we? On the other hand, if you're out of gas, you're out of luck.

Find and island and cut down a few tree's and rig a sailing sub...

aaargh!!

No. There are generators that are coupled to an electric motor.

So the electric motor uses power from the dead batteries to run the generator to recharge the dead batteries?

Sorry, I don't believe in perpetual motion.
