Staying on your ship when boarding.
 

How do you stay aboard your ship when boarding another. Its very useful especially when taking on really high leveled flag ships. I think you have to shoot your cannon when the captain presses BOARD, but I have'nt tried it out yet.

First your crew has to be more then the flagships capacity will hold. I doubt this will happen with a MOW or colossous. Although last night we went out with a fleet and had our sights on the Colossous. One ship at each side, the ship with boarding rights boarded, and the other helped take them out with the cannons.
