Imagine a situation -- a 32 gun xebec-frigate against a 14 gun brig. After boarding brig captures a frigate and take as a prize to home port.
Sounds like a unhistorical fun?
Nope. Actualy this is a real fight between HMS Speedy with Lord Cochrane as a commander and El Gambo which had grater firepower and crew - about six times the size of Cochrane ship (Or fight between HMS Sophie with Aubrey and Cacafuego ;-) )
So I would like to see in this game historical gameplay where there is no balance between ships (generaly: smaller ships are almost always weaker) but captin and crew with good skills and some luck shloud be able to capture / sink bigger ship.
