Ah yes, that makes much more sense
The S-Boot mod sounds like a lot of fun, actually!
What good is the 2cm Flak again surface ships, does anyone know? I've emptied 1000 rounds at the waterline of ~2000 Tramps etc with no apparent effect.
Just for a laugh, you understand, not during my proper career missions
PS. I've been looking at uboat.net's patrol reports, and it seems actually that uboats did indeed engage and sink trawlers etc, at least during Sep 1939. I've not yet looked too far as the war progressed... It would seem a waste of a torpedo to me, but the Kaleuns did seem to attack <1000t ships.
