    Swim north and over the bowsprit of the sunken ship.

    Enter the doorway on the right of the deck to find a chest.

    Continue along the deck to a gap where the ship is broken in half.
  4. 4
    Swim straight down the gap to find the section of ship wedged between rock cliffs.

    Inside this section, find an Animus Fragment.
  6. 6
    Return to the air barrel and use it to replenish your oxygen.
  7. 7
    Swim north across the gap to the north side of the ship.
  8. 8
    Find the entrance on deck and enter.
  9. 9
    Look down the hallway to the left for a chest.
  10. 10
    Return to the deck and follow it north to two sets of stairways.
  11. 11
    Look in the small alcove between the stairways to find another chest.
  12. 12
    Swim to the left side of the ship, over the edge, and follow the hull down to the seafloor.
  13. 13
    Look for a hole in the ship's hull and enter.
  14. 14
    Grab the chest ahead inside the hull.

    Return outside and face south; an Animus Fragment is on top of a section of rock directly ahead.
  22. 22
    Swim to the fragment, avoiding the shark.
  23. 23
    After grabbing the fragment, swim down to the floor below and use the air barrel to replenish your oxygen.
  24. 24
    Follow the path along the seabed to the south, using seaweed to hide from sharks.
  25. 25
    When you see the path on the left, swim up and over the eel, then back to the floor on the other side.
  26. 26
    Open the chest beneath the ship here and use the air barrel to replenish your air supply.
  27. 27
    Swim back and interact with the diving bell to return to the Jackdaw.
