In a Pirate version of Brikwars, each of the specialized types of mini-figures should have correlation to the crew of a ship or fort.
It would be nice to keep the number of classes to a minimum. Otherwise people (including myself) will not use them or care.
If anybody is interested in the types of crew that there were, I found a nice article on the HMS Victory that talks about the different types of crew that had served on the vessel.
Here is a list of Statcards I hope to finalize based upon the primary types of mini-figs provided in sets.
These only my first versions. I don't expect these to be the final ones I'm using, so comments and criticisms are welcomed. It was pretty easy to create these from the StatCard Generator, which means that creation and revamping these card is very easy.

Original
* 2nd Draft 
Captain (Imperial or Pirate) - Hero
Still trying to figure out his special abilities. Provided a couple of ideas in the StatCard above.

Original
* 2nd Draft 
Officer - Specialist

Original
* 2nd Draft 
Marine - Specialist
Known as Royal Marines

Original
* 2nd Draft 
Seaman (Imperial) - Trained

Original

Pirate - Trained
I assumed that they'd be exactly like a Seaman only much more brutal and depraved.
Villager - Incompetent
Thought I'd use villagers that are protected by Imperials in a game with the goal of pirates looting a town.

As a special note, the images in the StateCards were drawn by Hound Knight.
