I guess you could do with just 2 bearings if you rely on the fading length of the line on the map, but that is nearing on cheating reality. With only a single ended line in a specific direction you cannot judge distance. So you can't plot 2 such indefinate lines and get a course from that. At best you can tell it has a course to either side if the bearing drifts to left or right.

First of all, I think that you are woefully ignorant of just how good the GHGs were. I think you should start by reading
http://www.cdvandt.org/GHG1996.pdf to get some perspective. The distance between the GHG receivers was around 4.25x the distance between our ears, so as to take into account the different speed at which sound travels in water as opposed to in the air. Someone wearing these headphones could, therefore, point to the source of the sound as easily as you can point in the direction of a nearby barking dog.
Second, we know that GHGs came with a resistor that was used to decrease the level of sound. It came with hundreds of settings, but even assuming that it only came with 40, and assuming that a GHG can hear a lone vessel out to 20 km, that means that each setting shows 500 meters of range distance. Therefore the very idea that I should run around pretending that my GHG cannot tell me the approximate range of the boat is idiotic.
Furthermore, the very idea that using the capabilities that my u-boat comes with in the game, and most likely had in real life is "cheating" is insulting in the extreme. I do, therefore, request that you retract the statement.
