I was attacking a convoy the other night, I'd snuck inside it's first row and was attacking the ships at the core. I fired my front tubes at overlapping ships ahead of me and started to turn the UZO to check how far behind me the outter row was and well.. I'd misjudged things!
I was in fact in the direct path of the outer row and a ship was 60m from me, broadside! I went flank and started to turn towards it and got rammed slightly.
