Only 100 meters so far, haven't been in deep enough waters to really go deep lately, still patrolling off Ireland.
Did collide with something (probably an uncharted sea mount) in the Firth of Clyde whilst trying to sneak into the base there, unfortunately it destroyed my forward torpedo tubes and got me stuck on the bottom at 15 odd meters for an hour or so while I had to get the flooding under control.
As if that wasn't lucky enough, after I aborted the run into the Clyde, I was spotted on the surface by an aircraft which attacked me (no damage) but then called in a Destroyer which merrily dropped a happy string of DCs directly across my foredeck.
Thought about poor U-35 and Alfrons Elric last night and decided not to go DID as usual and try again, otherwise I'll never get past the start of 1940
I'm still quite new to this sim so I want to get the hang of things.
