Assassin’s Creed 4 Black Flag Resynced All Jackdaw Ship Upgrades

In Assassin’s Creed IV Black Flag Resynced, you need to fully upgrade your ship The Jackdaw to unlock the Ship This trophy & achievement.

To access higher tier upgrades you must also upgrade the harbmourmaster in Great Inagua, available after Sequence 04 – Mission 01: This Old Cove. For 12 of the final upgrades you must also find Ultimate Upgrade Plans in the world (6 from Underwater Shipwrecks, 6 from Treasure Maps).

You will also need a lot of money and materials. The best way is to conquer all Forts first, they give lots of materials and money and open up the sea map for Kenway’s Fleet minigame. You can always lower the naval combat difficulty in the game settings if they give you trouble. Then you can use Kenway’s Fleet to send your ships onto passive missions. Send as many Schooners and Brigs as you can. The schooners bring back money and the Brigs bring back materials. Opening chests (especially from Underwater Shipwrecks) also gives lots of money. You can also board Man-o-Wars in the hard difficulty regions and take the Captain’s lockbox to get around 5500 money each time. Should you be missing materials, use the scope to look for ships that carry the materials you need.
