Row boat of Paul Clark discovered off Washingon coast

The 16-foot row boat of a 69-year-old man who was attempting to row solo from Prince Rupert to Port Hardy has been found by the U.S. Coast Guard off the Washington state coast.

But there was no clue as to the fate of the boat's owner Paul Clark, who was reported missing July 11 after he failed to check in with a family member.

A crew from the Grays Harbour station in Westport, Washington, recovered the unmanned boat Friday about eight kilometres northwest of Ocean Shores, Washington, on Thursday.

Clark was last seen hundred of kilometres to the north in the vicinity of Aristazabal Island, British Columbia, about halfway to his intended destination in the non-motorized boat.

Coast guard officials say the crew of a fishing boat came across the capsized vessel and reported it around 7:30 a.m. PT. July 31.

The coast guard then launched two boats and a helicopter to the location which arrived about an hour later.

"They overturned the vessel and found all oars and sails secured. Crew members found the identification of Paul Clark in the vessel," said a statement released by the coast guard.

"Coast Guard boat and air crews searched the area for approximately three hours and found no signs of distress. The search was subsequently suspended pending any further information."

The row boat is now being returned to Canadian officials.
