View Full Version : Problems with my XXI

I have made 2 patrols with my XXI and there is 1 thing that really bothers me. The sub can´t keep the depth. If i set it for periscopedepth and have medium speed or more ahead, the depth changes between 8 and 30 meters. Up and down, up and down. The higher speed the more the depth changes. Especially in rough waters.
I never had these kind of problems with my IXD2.
Is it only my sub that behaves like this or is it a known problem with the XXI-sub?

Just a guess, but maybe it's your chief engineer's experience?
I never had a type XXI so i don't know anything else though. http://forums.ubi.com/images/smilies/16x16_smiley-surprised.gif

That happened to me during storms, the depth went from 5 to 25+ meters in seconds.. a bit tricky to attack convoys, that's what i can tell you http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif And yes, I have the similar problem.

Yes it´s pretty hard to attack convoys when the sub behaves like a roller coaster... http://forums.ubi.com/groupee_common/emoticons/icon_mad.gif
Do you know if there is a solution to the problem?

Wait for the storm to pass or turn off the realistic periscope rocking-about. It still won't help much if the boat finds itself in 25-30 meter depth

I just got into my first XXI, and yes, bad depth keeping with very high experienced helmslmen.

I also noticed that my Radar is 'destroyed' all the time, even when leaving on a new patrol. The radar looks like it's working at the radioman's station, but he's never reported a contact. The radar I have installed says it works even at snorkel depth! Too bad it doesn't work at all. http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif

One of the most difficult tasks presented to the crew of a U-boat/submarine from the WW2 era, was keeping the vessel level while submerged, if left to its own devices a submerged U-boat would not only rise and decsend - but more alarmingly, it would rapidly tilt its bow or stern downwards until it became vertical!
Keeping the boat level was a painstaking team effort for the boats helmsmen and needed constant attention -

This is probably why we didnt get manual control of the hydroplanes and ballast tanks in SH3, micromanaging bouyency would be a total nightmare and would quickly become very tediouse - as the smallest error on your part could have you nose diving your sub towards crush depth (or surfacing in front of an escort) in a matter seconds. (either way you end up as a scrap heap on the bottom of the sea bed)

Its probably better the AI handles things like this, can you imagine one guy running from compartment to compartment trying to operate the entire boat by him self? http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

AoD allowed control of the planes, dont recall ever going ballistic with it.

The XXI becomes easier to handle when there are masts above water when using Ahead Slow. The faster you go, the more difficult it is for the crew to control it (the less time they have to react to wave action changing the pitch/roll of the boat before drastic depth changes occur). This is to be expected...as they aren't used to operating a boat that has such a high submerged speed. Likely the solution is to get three senior rank POs with Helmsman, and a senior rank CE with the Helmsman qual. Having the navigator be senior and have the Helmsman qual should help as well. This is all theory, as I haven't worried about it, I like to approach my targets slowly anyway.
When masts are up (periscopes, snorkel, etc), keep speed under 8 knots and a reasonably experienced crew should be able to keep it under control (except in bad weather...but then it doesn't matter what type of boat you drive...).

The dive planes probably worked as they should, but the underwater physics wouldnt have been present or 100% realistic, this is good thing for the sake of gameplay! how are you supposed to set up a manual shot when you are too busy fighting the controls to prevent the sub from doing a kamakzi in to the sea bed. It would be nice if the dive planes were manually controllable in SH3/4, but not mandatory.
