Assassin’s Creed Black Flag Jackdaw Upgrades Guide: Repairs & Best Picks

The Jackdaw is your pirate flagship in Assassin’s Creed Black Flag Resynced, and keeping it in fighting shape is a big part of staying alive out on the Caribbean sea. To make sure you can push through tougher battles—especially when you’re hunting legendary ships—you’ll want to invest in Jackdaw upgrades and handle repairs as you go. This guide breaks down every Jackdaw upgrade you can unlock in Assassin’s Creed Black Flag Resynced.

Key takeaways

  • You can’t upgrade the Jackdaw until you reach the Prizes and Plunder quest in Sequence 3.
  • Upgrades and repairs are handled by harbourmasters, who also offer ammo and ship cosmetic items.
  • Upgrade materials come from gathering real-world resources like reales, cloth, metal, and wood.
  • You’ll earn those materials by raiding ships during naval combat, then upgrading in stages.
  • Jackdaw upgrades fall into four groups: ship, weapons, storage, and harpooning improvements.

Checklists

The Jackdaw is your pirate ship in Assassin’s Creed Black Flag Resynced, and you’ll need to keep it maintained with upgrades and repairs if you want to keep sailing through the dangers of pirate life. Strengthening the Jackdaw as much as possible is especially important if your goal is to take down legendary ships. This guide compiles every Jackdaw upgrade that’s available in Assassin’s Creed Black Flag Resynced.

How to Upgrade the Jackdaw

Before you can upgrade the Jackdaw, you’ll need to progress to the Prizes and Plunder mission in Sequence 3. When you arrive, the game runs a tutorial for boarding enemy vessels, then sends you to Salt Key Bank—an island outpost where a harbourmaster is ready to upgrade your ship’s hull.

Harbourmasters are located on islands throughout the Caribbean, and each one lets you both upgrade and repair your ship. In addition, they’ll sell ammo and cosmetic items for your ship, so you can customize and prepare without having to leave the area.

Every Jackdaw upgrade calls for a combination of reales, cloth, metal, and wood. You can collect those materials by taking part in naval battles—plundering other ships is the main way to stock up. As a result, upgrading becomes a gradual cycle: you improve the Jackdaw bit by bit, take on stronger opponents, earn even more upgrade materials, and repeat until your ship is fully upgraded.

Main Jackdaw Upgrades

Jackdaw upgrades are divided into four main categories: ship improvements, weapons upgrades, storage upgrades, and harpooning upgrades. Each category includes specific components you can enhance to make the Jackdaw more effective in combat and utility roles.
