Mac the Black's pirate ship was originally the flagship vessel of the Spanish Fleet. The Spanish Armada sought out Mac to recover the ship.
History[]
While Marty McFly was forced to work on the deck of the ship, he formulated a plan with Verne Brown to escape that resulted in the destruction of the ship, via a cannonball that was fired straight upward and fell back towards the ship. Afterward came the capture of Mac by the Spanish Armada, with the assistance of secret agent Maria.
