Retrieval of cannons from what's believed to be the flagship of the Pirate Blackbeard may be delayed by the lack of a heavy lifting vessel.
Divers with the Queen Anne's Revenge Project say they may have to wait until spring to receive the cannons. They had planned to raise them this fall.
Archaeologist Chris Southerly says the cannons can weigh between 2000 and 2500 pounds. Smaller cannons raised from the wreck off Atlantic Beach have weighed just 800 to 1000 pounds.
The shipwreck was discovered in November 1996 and is the oldest shipwreck found off the North Carolina coast.
