Full Map
All the ports, towns, hidden settlements and small islands are shown.
Tip: There are 2 locations, where you can get side quests - Calypso Island and Pecuny Harbor. You can use Hamilton's quests in Pecuny Harbor to lose your 'pirate' status instead of renaming the ship in smugglers settlements.
