Maybe on your ships, you would be able to have a door or something that will take you to the belowdecks of your ship, so you can have more people firing cannons or something, and possibly a brig along with it where NPC enemy prisoners could be held if you decided to take prisoners after sinking a ship. The prisoners could either be ransomed back to their respective factions or sold to bounty hunters or something. They could also possibly stage a mutiny against you, where if they win, you are put on an island, and they go back to their respective factions or something like that.
