I wasn't aware of any speed issues, but I've tested the speeds throuroughly and everything is normal.
For the Type XXI it has the following specs (found online):
Speeds:
Surfaced - 15.6kts
Submerged - 17kts (15.6kts with Snorkel/Diesel Active)
Ranges:
Surfaced - 15,500nm @ 10kts
Submerged - 340nm @ 5kts
The battery takes far too long to recharge though. Historically, it was able to recharge in under 5 hours. I'm not sure where to start with this though.
