After regaining control of your character, head onto the ship deck and speak with the marked men on your way.
After reaching your destination, you will be attacked by one of the crew members.
Optional objective: Limit Health Loss to less than 10%
Firstly you will learn how to parry enemy attacks by holding down the parry button. Your character will automatically reflect all hits.
After performing three blocks, attack the enemy with the attack button.
In the second fight, use the parry button again but this time press it right before getting hit. Slow motion will turn on and you will be able to perform a fast counterattack (attack button).
After getting beaten up yet again, the sailor will take out a knife and will try to kill you. Disarm him with the jump button right after parrying (during slow motion). That way you will end the brawl.
After a short conversation with the captain you can head to sleep to your cabin or play some logic games (marked on the map with dices).
Their rules will be explained in details before the game begins.
As the next day begins, head out of your cabin and speak with the marked crew members. After speaking to the last of them, you will be able to choose whether to speak with the doctor or the cook. The choice doesn't influence the further events in any way, but you will hear a slightly different dialogue in each case.
After hearing one of the men out, head to a man named James.
Afterwards check out the stern and go below the deck.
At the marked spot you will need to use Eagle Vision and examine the shining barrel on the right.
You however won't be able to learn why someone is throwing cargo off the ship, so return to your cabin and get some sleep.
After a couple days the ship will be attacked and you will get locked below deck, where you will have to fight with a mysterious crew member. In order to kill him, parry right before being hit and press the attack button when time slows down. That way you will end the fight instantly.
Afterwards a cutscene will begin, after which you will have to secure the riggings. Run from one point to the other and press the interaction button to perform the necessary actions.
The last point can be found on one of the masts. Climb it using the ropes and set the sail.
Optional objective: Rescue James under 40 seconds.
Optional objective: Completed all the constraints in one playthrough.
Then you will see James hanging above the deck with last bits of strength. Hold down the free run button and run forward. If you do it fast enough, you will not only save him, but also complete the additional objective.
After the storm ends, head onto the deck and speak with the captain. He will send you to the top of the mast, from where you will be able to see land.
The sequence will soon come to an end.
