Assassin’s Creed IV Black Flag Resynced has 15 Naval Contract Locations. Naval Contracts are little naval combat side quests where you destroy enemy ships. To make them appear on the map you’ll need to start out with the one called “A Spanish Plague” from the NPC next to the harbourmaster in Great Inagua. This is available after Sequence 04 – Mission 01: This Old Cove. They get revealed on the map when synchronizing the viewpoints.
Nothing is missable, you can still go everywhere after the story. You can see if an island has a Naval Contract when scrolling over it on the map. You can also press 
(PS5) / 
on the map to filter for Naval Contracts specifically. They reward you with money.
