Rivet City bow

About
Although technically a part of Rivet City, the Rivet City bow consists of the broken-off front third of the aircraft carrier. Pinkerton has set up his lab within the bow part of the carrier after being 'removed' from the Rivet City council in a coup.

Access to the bow is made via an underwater door. Some distance must be swam, and there is a hollow section half way along in which a breath can be taken. The entrance is guarded by Mirelurks, the exact amount/type depending on your level.

Another entry is south west of Rivet City across a bridge. The door is locked "Very Hard" (requiring a Lockpick skill 100) on both sides. Alternatively there is a power switch to the right of the door, when used this unlocks the door as well, but this can only be accessed from the inside of the bow.

There's a Big_Book_of_Science that may be stolen from a table in Pinkerton's lab.
