im not sure if this has been mentioned before, but I would love to see an additional ship be added. Maybe a small fleet. One ship just for raids, u fill this up to attack rival Captain and the ships could be used to fire on the bases. Subsequently, to counteract these ships the Fort could have Port Cannons added to fire back at the enemy ships. I think this would be a very fun and cool addition to the game and give long term players who have become bored more to upgrade.
