The aircraft carrier
As you swim towards the aircraft carrier, you see no obvious entry point. The carrier seems to just be a giant steel mass all along the sides. But you see an anchor that wasn't reeled in fully, which is hanging off the port (left side) of the gargantuan ship.
It takes you a few tries, but you get a firm grasp on the anchor, which you are surprised by, with your slippery hands. You manage to pull yourself into a sitting position on the oversized anchor. After regaining some of your stamina, you clamber up the rope which is holding the anchor to the craft. Once at the top, you squeeze yourself through the small hole from the rope to the room where the rope is connected by a winch mounted on the same wall as the hole. There is no one in the room, and it is medium sized, 6x8x6 feet, if you had to guess. The room looks like a workshop of sorts. A few jet engines lie discarded in a corner, and 2 more are up on a stand. One side of the room is covered in shelves and shelves of tools of all sorts and another mobile workbench is sitting near the one of the engines on the stand.
