Use grapeshot, aim for the deck

From Create Your Own Story

The concentrated hail of grapeshot decimates the Portuguese sailors with brutal efficiency. By the time the smoke clears, more than a dozen men are dead or wounded, while the others have abandoned their posts to take cover. Unable to complete her maneuver to shoot you, the galleon is now at your mercy. Time to finish this...

You command your men to prepare to board the other ship. But the remaining Portuguese sailors, too, are getting ready for battle. What now?

Shout to the sailors : "Last chance to surrender!"

Shout to your men : "Take no prisoners!"
