Cannot assign captain in captured ship

[kenlai112]

I have two officer , the netvigator who joined me in the early stage of the main quest, and the indian I recused from prison. When I boarded and captured enemy ships, there is no officer to choose in the assigning.

A few officers cannot become captain.
They are always given by quests. The one who came from the tavern or from surrendering captain can always become captain.

If you want to get a proper officer, you have to save scum in front of a tavern, and reload until an officer you want spawn.

Quest characters don't try to leave you.
Loyal character will, but not often. And you can still offer them money so they stay. ( last option, then first option in the dialogue)

The indian and the navigator from the tutorial cant be appointed as captain, ever. You will need to recruit any new officer for that purpose in tavern, or from captured captain, or captain on raft.
It is possible to recruit an officer if you are lucky with the tavern during the tutorial. As said above, just save before going to the tavern and reload till a recruitable officer shows there, helps if it is a new day and you havent visited tavern yet.

In general guys on floating raft have a lot of abilities already compared to those you can recruit on land. Saving/reloading on world map just before the encounter with the raft makes the captain different each time so you can try to get a great captain with many abilities (saving/reloading during the encounter wont spawn a different captain)
