Warping or kedging is a method of moving a sailing vessel, typically against the wind or out from a dead calm, by hauling on a line attached to a kedge anchor, a sea anchor or a fixed object, such as a bollard. In small boats, the anchor may be thrown in the intended direction of progress and hauled in after it settles, thus pulling the boat in that direction, while larger ships can use a boat to carry the anchor ahead, drop it and then haul. 
For example, the sloop Adventure under the command of the infamous pirate Blackbeard ran aground attempting to kedge the Queen Anne's Revenge off the bar near Beaufort Inlet, North Carolina in June 1718. 
An anchor is a device, normally made of metal, used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ancora, which itself comes from the Greek ἄγκυρα (ankȳra).
Edward Teach, better known as Blackbeard, was an English pirate who operated around the West Indies and the eastern coast of Britain's North American colonies. Little is known about his early life, but he may have been a sailor on privateer ships during Queen Anne's War before he settled on the Bahamian island of New Providence, a base for Captain Benjamin Hornigold, whose crew Teach joined around 1716. Hornigold placed him in command of a sloop that he had captured, and the two engaged in numerous acts of piracy. Their numbers were boosted by the addition to their fleet of two more ships, one of which was commanded by Stede Bonnet; but Hornigold retired from piracy toward the end of 1717, taking two vessels with him.

Stede Bonnet was an early eighteenth-century Barbadian pirate, sometimes called "The Gentleman Pirate" because he was a moderately wealthy land-owner before turning to a life of crime. Bonnet was born into a wealthy English family on the island of Barbados, and inherited the family estate after his father's death in 1694. In 1709, he married Mary Allamby, and engaged in some level of militia service. Because of marital problems, and despite his lack of sailing experience, Bonnet decided he should turn to piracy in the summer of 1717. He bought a sailing vessel, named it Revenge, and travelled with his paid crew along the Eastern Seaboard of what is now the United States, capturing other vessels and burning other Barbadian ships.
Queen Anne's Revenge was an early-18th-century ship, most famously used as a flagship by Edward Teach, better known by his nickname Blackbeard. Although the date and place of the ship's construction are uncertain, it was originally believed she was built for merchant service in Bristol, England in 1710 and named Concord, later captured by French privateers and renamed La Concorde. After several years' service by French sailors, she was captured by Blackbeard in 1717. Blackbeard used the ship for less than a year, but captured numerous prizes using her as his flagship.
Mary Ormond or Ormand was the wife of the notorious English pirate Blackbeard.
