Thanks a lot for your responce!
I think your probably correct about the southhampton being in a convoy that is causing the problem. Im not sure, but I believe I was able to classify a southhampton while it was sailing on its own. Never seen one inside a convoy untill now, so that "could" be the problem.
I was looking around in the SH3 sound folder and found you are correct that the ships are in a number of of broad generic categories. I wanted to know how each ship is linked to the sound file. Is it just a command line in the ships cfg file? I was thinking it might be possible to specify a specific sound for each. I don't really plan on doing custom sounds for each, I just wanted to give the Southhampton the same sound as the Fiji Light Cruiser since their simmliar.
(Edit: Just so there isnt confusion, it not that it wouldnt just let me just classify it as a Southhampton, the game wouldnt allow me to classify it as anything. Like when you put your scope over a merchent or a warship the game will display what "type" of ship it is on the notepad in the upper right corner of your screen. When I put the scope over the Southhampton it wouldnt display anything, it was just blank with the - like my scope wasnt over any ship.)
