torpedo damage

[slow_n_ez]

I try not to waste too many torpedos since the VII 7 I have don't carry as many as the bigger subs .... I usually send one torpedo into any ship ( except the liners they get 2 ) and then wait and follow it and watch it take on water from my hit .. Most times the ship will sink after an hour or so ..... but not always , so then its another torpedo or deck gun time ..........
