I understand that it is done to have real silent running and to avoid being heard by the enemy ships. However, this low velocity feels adequate for the normal "U-boats", but not for the Type XXI. If I understand it properly, the noise emited by a submerged U-boat in SH3 does not depend only on its raw velocity, but on the percentage of the maximum possible velocity it is actually using... am I right? In that case, the safe "silent running" velocity for a Type XXI should be much higher than that for the other U-boats... am I right?
Thank you very much for your help !!!

P.S. In real life, the Type XXI had a "creep" motor that allowed it to navigate under water at moderate velocities and producing very low noise. This seems another important advantage of this U-boat and it would be very good to have it modelled somehow in SH3 !!! (for example allowing it to navigate submerged at moderate velocities (higher that 2 knots!!!) without being detected by the anemy hydrophones).

OK the best suggestion I have is that I dont know how to change the speed assigned to the order for silent running maybe someone from GWX will stop by with that, in the meantime what I suggest is this
in the file Ubisoft/SilentHunterIII/Data/Submarines/NSS_Uboat21/NSS_Uboat21cfg
you will find this

what you can do is figure out what percentage of your top underwater speed adds up to 5 knots and enter that percentage as ahead slow speed above, notice that no percentage symbols appear in the settings, here percentages are expressed as decimals
the Idea being that when you order silent running immediately after hitting the z to order it you immidiately hit button 1 to order the speed you desire Your Type XXI is equipped with Creeping motors in the game while under silent running they will be engines used.
I once swapped them out for the engines on my type IXB as my reg motors.
also with GWX bouancy you should when at 0 knots you will drift approx two metres above ordered depth this can cause your conning tower to broach. you can adjust periscope depth here but the problem isnt a problem over 4knots so you may not need to.
hope it all helps MM.
