I just found the Yangtze Sub (in the harbor area by "The Shamrock Taphouse" talk to a kid on the docks.) to start the quest "Here there be monsters". I was just wondering if you can go back to the sub after you have completed the quest. Any info if you can or not would be greatly appreciated.

You can go back.

Thank you!

I'm not sure what or who the punchline on that was.
