Mistakes that block the 544, 693 treasure

The biggest mistake is sailing straight to 544, 693 without picking up the Mariguana Island treasure map. Even if you know the coordinates, the buried treasure is tied to the map, so collect it from the Mariguana cave first.
The other mix-up is the name. The Andreas Island treasure at 544, 693 uses the map from Mariguana Island. The Andreas Island treasure map is a different collectible that sends you to Abaco Island at 586, 811 for a different reward.
After claiming the Harpoon Strength Ultimate Plan
The main reason to grab this chest is the Harpoon Strength Ultimate Plan, which feeds into the final tier of harpoon upgrades for whaling. Once it is collected, check your upgrade path and spend the required materials when you are ready to push whaling gear higher.
If you are clearing treasure maps, the next natural target is the separate Andreas Island map that leads to Abaco Island at 586, 811. After that, keep working through the remaining treasure maps and ultimate ship plans so the Jackdaw’s upgrade list stops being gated by buried plans.
