Île à Vache sits in the Navassa region of Assassin’s Creed 4 Black Flag Resynced and holds 10 collectibles for its completion tracker. The island packs a viewpoint, a tavern, two Assassin Contracts, one Naval Contract, a money chest, three secrets, and a single data file into a compact area. Clearing all of them fills the local tracker to 100 percent.
Quick answer: Sync the viewpoint first to reveal most markers, then work the northeast corner for the secret chest and treasure map, grab the tavern, letter, and money chest, and accept both Assassin Contracts plus the Hunter Gatherer Naval Contract from the coop and dock. The data file appears only after you take the “The Slave Master” contract.
All 10 Île à Vache collectibles
Île à Vache is found at map coordinates 809, 109. Markers appear when you synchronize the viewpoint or move close to a collectible, so climbing the viewpoint early saves time. The full set breaks down like this.

| 10 | Naval Contract 1 – Hunter Gatherer | Accept from the man at the Jackdaw dock |
Three secrets and the treasure map
The three secrets are spread across the northeast and west of the island. Two of them, the chest and the letter, are self-contained pickups. The middle secret is a treasure map that sends you off the island to dig up its reward.
Secret 1/3 (Voynich Manuscript Chest): Head to the campsite in the northeast corner. The chest is tucked under a covering, so look beneath the shelter rather than out in the open.
Secret 2/3 (Treasure Map): Walk the beach shore in the northeast and search a skeleton to pick up the Île à Vache map, which points to Jiguey at 534, 510. Enter the Jiguey cave, swim past the section with pirate enemies toward the beach where a brute stands, and dig the treasure on the right side of the sand between the palm trees.
Secret 3/3 (Letter, “Taking My Leave”): Cross to the western side of the island and check the shore for a bottle. The letter is inside it.
Tavern, money chest, and data file
These three sit on the ground and depend on a bit of combat or story order.
Tavern: Go to the tavern marker and order a drink. That triggers a street fight against 5 enemies. Defeat all of them to unlock the tavern.
Money Chest: The chest is in the small encampment on the south of the island, watched by a group of British soldiers. Clear or slip past them and open it for coin.
Data File: This one only appears after you accept “The Slave Master” Assassin Contract. Once the contract is active, the data file shows up among the bodies on the southern end of the island’s shore.
Note: Because the data file is tied to the contract, take “The Slave Master” before you try to collect it, or the pickup will not be there.
Assassin Contracts and their bonus objectives
Both Assassin Contracts start at the pigeon coop in the center of the island. Each has a bonus payout of an extra 500 Reales if you kill the target the right way.
The Slave Master: Accept it at the coop, then travel to the encampment on the southern end where the Slave Master patrols the beach. Kill him from a stalking zone, meaning the tall grass, to earn the 500 Reales bonus.
The Expedition: Accept it at the coop, then head to Cumberland Bay in the center of the island where the privateer leader stands. Take him out with an explosive to claim the extra 500 Reales.
Naval Contract: Hunter Gatherer
The island’s Naval Contract, Hunter Gatherer, is handed out by the man on the dock where you moor the Jackdaw. The task is to sink Hunter Ships, but they will not spawn until you raise your wanted level.
Confirming full completion
Île à Vache uses its own completion tracker, so once all 10 collectibles register, the island reads at 100 percent. Nothing here is missable. Even after the story ends, you can return in free roam, and locations gated behind story progress open up as you advance. If a marker is not showing, sync the viewpoint or move closer, since collectibles only appear on the map once you approach them or synchronize.
With the viewpoint synced, both contracts turned in, the Naval Contract cleared at sea, and every secret, chest, tavern, and data file collected, Île à Vache is fully done, and you can move on to the rest of the Navassa islands.
