It's tuff business!
I always try to make every Torp that Uncle Karl gave me count! Sometimes I have to decide if a ship needs more than 1.
A spread of 2 - decent spreading angle- for the biggest- before they know I'm there- and single ones for the small ones.
I used to be too careful with the torps and always tried to use one each ship! But I always ended up using more or missing!
You live and learn!
Toss Bernard overboard and claim the rough sea washed him out of the tower as he was attending the watch!
