Is this mod you have mundio_73a?
US Navy Nuclear Submarines by jhapprich
ETR3(SS) is another nuke modeler... there is another fellow, but his name escapes me just now. ETR3(SS) recently retired from SH4 modding, but it keeping up via PMs. I have not seen jhapprich for a while... Anyway, if that's the mod, I'm not sure that was intended as a release version. It may have been, but there are some "backup" folders and files in there. In the meantime, if that is the mod you downloaded (or similar), then this should get you the bearing marker that I am guessing you are after:
NautilusShp.7z
You will need
7-zip to open that mini-mod. It is a dds file that gets put into the NSS_571 folder. It is basically a copy of CapnScurvy's 1500 yard bearing tool, which is similar to the files Webster and others made.
Your second image there is a "wake" issue with the boat. There is a node in the sub's dat file that would normally be named "NSS_571_ShipWake", but since jhapprich used the Balao as his basis, it is named after that sub with "NSS_Balao_ShipWake", which is linked to a node in the val file of "GeometryShipWake". Some of the settings in that val file are slightly different than "normal" submarines, and perhaps those are throwing things off a bit. I'll try to find time to experiment with that on my machine sometime later.
