Having piloted a few twin screw, normal surface boats I can say that it's not QUITE as good as a "spin on a dime" tank... especially not a hull as long and narrow as a sub. You'd need bow thrusters for that. But the turn rate should be far better than in the game, especially at low speed. It takes forever to do a 180 deg. turn at ahead slow, submerged, and the radius is huge. I usually end up doing a series of forward and reverse turns to keep the radius down, if I'm trying to maneuver for a second shot inside a stalled convoy.Originally posted by RedTerex:
Very interesting, I didnt know that !
I suppose, bit like how a tank can turn on its axis...
One thing I'm not sure about though, is if counter-rotating props would cause cavitation and more noise, when trying to run silent at low speed? Maybe increase your chance of being detected with hydrophones? If so, then maybe the slow underwater turn rates are realistic. In other words, counter-rotating props might be used for docking in port, but maybe not underwater with evasive maneuvering? Does anyone know? I'm just sorta guessing here. I do know that counter-rotating when docking a surface boat does churn up a lot of water.

Not to mention wave interference, which would undoubtedly decrease overall propulsion, if not turn efficiency. The increased turbulence could certainly negate any benefit from using both screws in opposing rotation, in such close proximity. Theoretically.I do know that counter-rotating when docking a surface boat does churn up a lot of water.

Bow thrusters are a blasphemy in the eyes of the lord! Did the lord tell Noah to put bow thrusters on the Ark?Originally posted by Frumpkis:

When Admiral J. Christ calmed the sea, did he add bow thrusters to the boat?
Did Jason's Argonaut have bow thrusters?
No!
Look, I have had the pleasure of working shrimpers out of Key West in my prime years, and we never saw the need for bow thrusters, nor would we have angered the gods by adding such an item to a vessel!
And before anyone says something about the examples I stated dealing with ships that did not have engines on them, well, I can say this...
The gods could have told the builders of these vessels how to build a diesel engine, and given them the technology to do so, however, they choose not to simply because life at sea is to be challanging!
And for the record, the sea going icecream maker was a devine insperation by the gods for the faithful!
As for the crush depth issue, may I remind you folks that a few of the US fleet boats managed to go below five hundred feet and return? Granted, the dive to that depth was not intentional, since there was flooding involved, (I believe some YANKEE landlubber from north of the mason dixon line probably forgot to close a valve or something) and caused the situation. Although, officially the cause was always listed as 'damage due to depth charge attacks.'
Thus endeth the sermon.
Now then, after reading this, all must follow the commandment of "Go forth, drink beer, and chase women, unless you are married, in which case, return to completing your assigned tasks on the never ending 'honey do' lists.

Arrrr... matey, I hear ye! Thrusters are for lubbers.Originally posted by jlf1961:

Can't have mattered that much, the large majority of U-boats went a lot deeper than 600 feet---and never came back upOriginally posted by jarmstroHX229:
However, surely depth did matter. For instance I understood that for the greater part of the war depth charges (British) were manufactured to a maximum depth rating and that the German Subs could actually go deeper than the depth charges could, and so were immune if they could get down fast enough?

Very interested. One of the best parts of both SH3 and SH4 is learning the history of the naval war in WW2.Originally posted by BBB462cid:
Not exactly interested in the Historical aspect, eh?
I wish.So you're an expert on both submarines and automobiles? Impressive
I'm British. I suppose the correct insult would have been "Captain" or "Commander", not herr kaleun.Compared to what? Type IIs? The Kreigsmarine's large seagoing boats were much the same, herr kaleun. Or have you forgotten that the USN had to deal with traversing vast reaches of open sea, unlike the romantic Type VIIc's role of operating relatively close to shore for the most part?
So you're saying you're no good at the game
I wasn't much good at it to begin with but I'm getting better all the time.
The subs you drive around in the sim world? or the real ones? Ever read a history of the USN's sub service?
To be honest I hadn't realised just how significant the USN's sub service was in WW2 until SH4. All our literature/films etc seems to be entirely focused on the U-Boat war. I will certainly be reading all I can about the USN sub service and would welcome any recommendations for books. I found some great USA web sites but would like to learn more about the people involved and their personal stories. What sort of people were selected and how did their experiences differ from the U-Boat crews etc.
No, it was quite a good attempt at trolling!This thread is a bad attempt at trolling.
