Perhaps I didn't write my question specific enough :yep:
Why didn't Kriegsmarine U-boats submerge at night for the purpose of listening for merchant shipping on the hydrophone. Surely you can hydro-hear a darkened ship/convoy further at night than you can see it? Yes, once a hydro contact is made and rough position/course established, U-boat would surface and race at full speed intercept course for the hydro contact. Approach and attack surfaced of course (before escort radar). Only spotting at 5-25 km range pre-approach until visual contact with the aid of hydrophone. |

That's what rdf, other boats sightings/beacons, BdU info. etc. was for. |
The hydrophones were a very unreliable tool, an aid at best. That’s why the doctrine was to stay surfaced to search for contacts and only submerge and listen if compelled to do so. This doctrine is reflected in the commander’s handbook. I would recommend reading the book “Secret Diaries of a U-boat” by Hirschfeld, he was a radio man and that book lays bare the real shortcomings of hydrophones. They were dependent on the salinity of the water in sea areas, the plankton content, many factors affected their usability. His skipper, the ace Bleichrodt, had very little use for them as is evident in the book (apart from using them to evade, and even then he doesn’t trust it - his words: “what’d I tell you Hirschfeld, the tech is ****”)
No game gets hydrophones right. They are highly overpowered in every sim I’ve ever seen. |

I took a look at Uboat.net

So it is hard to tell a final conclusion. Seems that we are left with the first hand accounts of the people using the hydrophone. Also I have to believe that if using hydrophone at night would have granted a significant advantage, surely the U-boat crews would have seized it. Hundreds of crews had spent thousands of hours at sea, so I imagine they tried everything to increase tonnage sunk. |

To often specs. of equipment/weapons used in games are "laboratory" specs. vs. specs of use "in the field". The two rarely are the same. |

What I wish we had is Vorpostenstreifen, the patrol lines set up by BdU north to south. He would even tell boats “travel x degrees at x knots til further notice”. We are way more on our own in these sims than they were in real life. BdU dictated their every move in most cases. It would be nice to get more orders like that. |
I started a discord server called War Room. It's a war game channel, but I also have a channel for SH5. Come on over and join me and others for games and chat!

Back from a long break on SH5 for lack of time and work reasons but coming back again! And I see this thread it's still going very strong so hopefully I will be able to contribute. But happy to see I have 6 or 7 pages to read through.
