Is U-boot bow spray....

what am i missing ?
nobody knows??
maybe kpt Lehman(he left the 'sense' that it is not supposed to be spoted at night) is able to give me a more satisfing answer.

Maybe the Averoff's crew have alert lookouts, but the tanker's crew were all playing cards in the boiler room?

Actually that's aa very good point.....the crew rating of said naval vessel could well be higher than that of the merchant.

Go into ME and check them out.

LOL....i prefer the invisible situation (small tanker) !
the plan is to ...kill the enemies with lugers pistols
of course,we will put silencers on the lugers....in order not to hurt the silence of night !

makman,

Following you PM, which directed me here...

I've only skim-read this thread, but here are a few things to keep in mind.

1) Specifically with regards to the Averof example you gave, did it open fire on you? Does it have radar? I ask because if an enemy ship "sees" you with radar, it will move towards you but not open fire until it sees you properly (with visual sensors).

2) In the general case, keep in mind that the height of the visual sensors on the ship (presumably quite high on the Averof) and the veterancy of the crew (also presumably higher) both affect visual detection.

3) There are many other factors as well. The night colours in GWX3 16km (which do affect sensors, and which were set by me) are set in such a way that you can sometimes be spotted by visual sensors on a clear night, especially in calm water, but visual detection on a dark overcast night is highly unlikely, especially in rough weather. FYI, the factors I'm aware of are: the water state (calm = easier to see), the amount of light (less at night, obviously, but also less in overcast weather, in my/GWX environment, both at night and during the day), the observed ship/sub profile (the size and orientation of the ship/sub being observed), the observed ship/sub speed (slower = harder to spot), the observing ship/sub sensor height (ships with higher watch towers can see better), the observing crew veterancy (experienced crews can see better), and the number of observing sensors (more ships = more eyes, and some ships may have multiple visual sensors). There may be others which I can't think of or remember right now.

One more thing just to ask here:
If im on surface and im using diesels,will DD or any other ship that have passive sonar detect me ?Even if it is pitch black night and there is fog and overcast..?
In other words ,will DD use passive sonar while im on surface or AI waits to sub dives and then "switches on" passive sensors?

[Commander Gizmo]

I may be mistaken, but I believe that passive sonar can only hear things that are under the water. Their sonar is on the bottom of the boat and can't distinguish surface noise, right?

At any rate, I've never been detected at flank on the surface due to desiel engine noise; but the instant you dip under the water they are on you like crazy if you aren't at silent running.

I'd just like to add some comments to what is being discussed here, and specially to the pictures posted ny makman some time ago:

Yes, you can see the U-Boat yourself close to the ship, and that might lead you to think that the ship should see you too. However, we KNOW positively two things: A) U-Boats were able to attack from as short as 500 metres without being sighted first, B) But most important: In those same conditions, U-Boats were able to see the target and even estimate its speed and AOB!

Hence for gameplay purposes, when we are constraited to a virtual world within program's limitations, we should be able to see the targets reasonably without being spotted ourselves. Forget the picture you see in the screen, as it does not, and will never correspond to an actual situation (And external light, monitor settings and screen resolutions are limits to that). What matters most are correct results, and I think so far in OLC's mods we are getting them

[BigBadVuk]

I remembered now,that ,while reading about last operation of BC Scharnhorst i founded that even if it was dark (polar night condition)and blizzard conditions,they stil managed to use their optical finders to track targets and shoot back.Even if that was very poor ,compared to newest H2S radars and radar controlled artilery systems (cm bandwith)that Brits used,they were not totaly blind.
So when did Zeiss company started to make night binoculars ( for use on purporse during night) and when similar optical equipment was issued to U boats..If this is off topic im sory but this idea question just materialised in my mind reading previos posts.

[Mopy]

I seem to recall an article relating to Brits getting their hands on a pair of UZO binocs, and the captor on testing them commented that compared to the U-Boats, they were (visually) blind at night.

Shame I can't remember where I read it.
