This is the Gaming Board on which the Pirate Ships sail to plunder the trading routes.
Each empty space usually contains a Merchant Ship card that the Pirates can plunder, whilst in the ports you can do some smuggling!
The space on the left reppresents the port village of Nassau, here you will position the upgrades and crew members for you ship.
The last Pirate Captain is somewhat mysterious...
The Fourth Pirate Captain is a red haired lady!
