"John Smith is a vicious pirate as well as an accomplished carpenter. His family had been wealthy landowners who lost it all when the Royal Navy unlawfully confiscated their estates. Smith was forced into becoming a working man. He quickly found work as a ship's carpenter, but he never forgot the Navy's treachery. So when Captain Jack Sparrow offered Smith a spot on the Black Pearl, he jumped at the chance to regain his fortunes. After the crew split up, Smith was commissioned to refurbish a sloop rig for Andrew Bowdash on Tortuga. Bowdash intended it to be a gift for a fair young maiden named Gretchen, as an incentive to marry him. But his nuptials would be delayed.
Smith got anxious to return to the adventurous life and started running rum for a local distillery. Seems he "borrowed" The Gretchen, had a scrape with a Navy Panther, and ran her aground on Driftwood Isle. Since then John Smith has been trying to make repairs, seeing as how he was advanced the entire fee! He can't return to Tortuga empty handed so you must help Smith out - or he'll never get to rejoin Jack's crew.
