Officials say a 55-foot yacht has washed ashore on the North Carolina coast, the latest vessel to be victimized in shifting sands in recent months. The National Park Service says the Vivens Aqua ran aground around 1 a.m. Tuesday near the south end of Ocracoke Island. Investigators did not say what caused the the yacht to run aground. The National Park Service said it is working with the U.S. Coast Guard and the yacht’s owner to have it removed from the beach. The Virginian-Pilot reports it's the fourth vessel to become stuck since late November.
