Hello,
U53, 9th patrol, BF15. Heavy storm and seas. 2 eels left.
A Passenger Cargo comes into view <500m. Went to PD and fired off both remaining torpedoes, both hit and I was even aiming at the forward part of the vessel. Darned thing would NOT SINK!

Stayed on the surface to hopefully view it's demise, and used the time compression to speed up the process. Anyway, after about 5 hours the cargo was still afloat and what to my wondering eyes should appear... a Tribal class beating down on me at <500m. Crash dived but to no avail, I was practically dead before I hit PD, then the wasserbomben. Well that's it for me!
I know this has been posted here before, but I really wish that there could be something done with the damage model for passenger Cargo ships.
With GWX1.04 on the horizon, I am wondering if there can be anything done about it's long sinking times.
I think for now, I'll let the P. Cargo ships go by, I mean for around 2000 tons and a ridiculous sinking time, it's just not worth it.
Thanks for listening to my gripe, and if there is anything that could be done, a big thank you!
