Something I thought of while making some custom ship stats was, so if a named crew with the cargo master keyword is linked to a ship, does that mean that the cargo hold of the ship would be expanded by one? the ability text of cargo master states that a crew with this keyword take up no cargo space on the ship it is placed and the linking makes an extra cargo space.
Yes, the ship would get +2 cargo spaces overall as long as the CM is of the same nationality as the ship, one from the link and one from the ability.
And also with the treasure ship keyword it makes all crew take up no cargo space, and with Admiral Zheng He and The Headhunter they are linked to their respective Baochuan and Guichuan. That means they gain an extra cargo with the linking and they take up none because of treasure ship.
Is that right?
Correct!
