nope, it's not possible. A lot of modders, including me, have tried to add such feature but so far all attempts failed. Standard problem is that the torpedoes fire north. With a lot of tweaking I found a way to work around that problem once. Torps fired, headed straight for the target but on impact.... nothing, the torp went straight through the target as if it weren't there
all those poor non-Dutchmen that must be wondering what your sig says, Nicolai... And I ain`t gonna tell them
