For many reasons it has not been practical for the NYGM Anti Humming Bird Mod to be released as a single mod until now.
The NYGM Anti Humming Bird Mod is now available to install into Grey Wolves and ndrifter’s Longer U-boat Repair Times mod.
The Mod is under the NYGM download section at our web site at the
NYGM Tonnage War Web Site
For hose unfamiliar with the NYGM Anti Humming Bird Mod, it is a feature where the u-boat can no longer hover at all stop. At all stop, the u-boat will slowly sink at a very slow rate. I would have preferred to have positive buoyancy but this has too many bad side effects vs reward.
I know what your thinking, “Oh no! I am going to sink and die when I get to the crush depth because I wasn’t glued to the computer screen!!” Thankfully not. For the VII U-boat to reach its crush depth of 346 metres it will take 3 hrs and 48 minutes to happen.
At speeds of 0 knots you will slowly sink at the rates listed below. At speeds of 1 knot you can maintain depth but not change to a lesser depth. To change depth you need speeds of 2+ knots.
Sink rates per 10 metres at 0 knots is IIa = 12 minutes; IId = 15 minutes; VII = 16 minutes and the IX = 21 minutes.
NOTE: The VII u-boat will take 3 hrs and 48 minutes to reach its crush depth of 346 metres
The NYGM Anti Humming Bird Mod was designed for the Type II, VII & IX and as a result breaks the XXI.
Additional fixes
With the NYGM Anti Humming Bird Mod now when the Type II batteries are destroyed this will result in 100% loss of battery power and not 75% as was the case previously.
Compatibility with other Mods
The NYGM Anti Humming Bird Mod is compatible with all mods including Grey Wolves 1.1 & nvdrifter’s various longer/extended repair mods with the proviso that the NYGM Anti Humming Bird Mod breaks the XXI.
Special Note for users of nvdrifter's various longer/extended repair mods. The NYGM Anti Humming Bird effect may cause increased depth keeping difficulties.
I quote lurker_hlb3 "The various NSS_Uboat*.sim files within the Data\Submarine\ of this mode are not compatable Grey Wolves as it makes changes to the basic performances of the subs: I.E. Surface Range/Sub-Surface engine power and range (Real Battery Life AKA Advanced NASA Battery Fix v2). Special note: the NSS_Uboat*.sim files are “not required” for the NYGM Anti Humming Bird Mod to work."
I will investigate this... I quote lurker_hlb3 "The NSS_Uboat2A.sim file is has a different file size 2744 v 2714. This causes changes in the binary offset addresses. If any one is using SH3 Commander 2.5/2.6 to make changes to this file, the file will be corrupted at load time and SH3 will “hang-up” and fail to launch."
Compatibility with other Mods when using SH3 Cmdr - thank to lurker_hlb3 for finding this
I quote lurker_hlb3 "The various NSS_Uboat*.zon files within the Data\Submarine\ of this mode are not compatable Grey Wolves or any other mod that use SH3 Commander 2.5 or 2.6 to mod and launch SH3. This is due to changes to the binary offsets that are within the various NSS_Uboat*.zon. If a user launches GW or any other mod with SH3 Commander 2.5/2.6, when SH3 Commander changes the “crush depth”, the NSS_Uboat*.zon file will become corrupted and SH3 will “hang-up” and fail to launch."
This can be resolved by replacing the text below in the SH3 Options.cfg
in the SH3 Options.cfg replace the crush depth values as per below ;----------------------------------------------------------------------------------

Rezoned U-boats
NYGM have redesigned the u-boat damage zones to be historical in size and location from u-boat plans so that damage is better represented (see image below). Note for example how we have reduced the Bow Crew Quarters from being larger in size than the fore torpedo room to the size of the sonar/radio room and relocated the Stern Quarters to the correct location.
We also reduced the torpedo damage zones and as a result the torpedo room can be damaged without the torpedo tube being damaged or visa versa. We have also greatly reduced the size of the engine zones and at the same time moved them further into the centre of the u-boat.
CRASH DIVE BLUES...
Let me start by saying that the interrupted crash dive behaviour is evident in a vanilla install of SHIII 1.4b, this "feature" is brought to the fore by the NYGM U-Boat Mod.
If you order a crash dive and before the u-boat reaches the crash dive depth (normally about 70 metres) you order the u-boat to another depth (higher or lower) then what happens is that the u-boat sits down by the stern at an angle of about 10 degree angle!!! The only way to get the u-boat back onto an even keel is then to order another crash dive and of course let it complete.
Due to the abundance of positive buoyancy that allows the U-Boat to hover like a Humming Bird this "feature" was not seen by the player. It would have however made the u-boat sink or sink more severely when the stern of the u-boat was flooding but this is something that the player would have expected and hard to tell the difference between flooding occurrences.
So if you order a crash dive ensure that you let the u-boat go the full distance, you can however change speed & direction without issue.
