Well I made it through, sort of.
I went along at about 2kts the whole way at around 200m(this time I didn't drift deeper) and got pinged on two different occasions. The first time I got away by maintaining speed until he went into his run across my bow and setting ahead slow as my new speed to get passed the depth charges, returning to 2kts after about 200m away from the line of DCs, I let loose a decoy and continued on with about 5 DDs and 2 elco's circling the decoy. Same thing happened the second time with the same result. I seem to have found a new way to escape DDs without turning or going deeper!
About 2 minutes before this screenshot was taken, I was going at snorkel depth(16m) and running at ahead one-third when some aircraft missed me with their bombs, put the snorkel down and I'm moving at ahead slow @ 16m. Repairs are finished(hull's still @ 100%) and so I'll continue on until nightfall to put the snorkel back up(those aircraft probably just saw me as I've got the radar fix and the snorkel was barely out of the water).
On my way back I think I'll try moving along the southern coast of Africa to avoid the heavy traffic.
