I found it almost empty around that time. Go for Gibraltar, its worth the extra hazzle. (Not recommended as someones first harbour raid)
HunterIXC: Good to finally see you in a decent boat!
For me it will always only be the VIIC.
Pros:
*The best looking sub
*Nimble
Cons:
*Range
It is by far the best subs to go harbour-fishin` in, and excellent at avoiding depth charges. I tried that in a IX D2 once, and got smacked around pretty badly.
