Bar tender drinks for everybody
I just returned from my 3 rd patrol, dec 1939 - Jan 1940, on a type VII B boat, 90% realism.
Total tonnage this patrol is 106 K ton.

The biggest contributor was HMS Nelson with 36,000 tonne. It was in a convoy that I attacked. It took 3 torps to sink it.
The patrol last longer than I expected, and I had to be really picky. I encountered many small ships (small freighters, passenger cargos) but I left them alone cause they're only 2000 ton or something. I only attacked small ships using deck guns, and opportunities to attack small ships were limited by the wheather condition. When wheather was bad, and I couldn't use a deck gun, I let those small ships passed by.
Here's the status report
And here's my patrol log:
