BOSTON (AP) — The U.S. Coast Guard says it has located the owner of an unmanned sailboat that washed ashore on Martha's Vineyard.

After an extensive search by federal and local authorities, the unidentified owner called the Coast Guard, claimed the boat and explained he left it on the beach.

Watchstanders had got a call around 10 p.m. Friday about an unmarked 13-foot Hobie Cat "Wave" model that had washed ashore with its sail up and rudder down. Authorities said it had lines hanging and dirty footprints on deck.

Boat and air crews searched the area for people in the water from the Vineyard to Naushon Island. Police also went door to door in search of the owner.

The Coast Guard says it's important for boat owners to document their vessels and make them easily identifiable.
