Missing a spot on the Flying Dutch...ship...?

I think on the map they call it "The Locker" but it is the flooded hull. To go there you have to be at the part with the Mutiny quest. What you have to do is try and appease the crew by getting rum and gold. on just over the right side of the ship, between the ship and the island, should be a bottle with paper sticking out of it. That is the treasure map and will tell you get you the flooded hull/ Locker. To get to it, just go to the floor with the hold and look for an open latch with sparkles and there you go.
