OCEANSIDE, Calif. -- The search for a missing Oceanside couple whose fishing boat washed ashore just north of Rosarito, Mexico, is in the hands of the Mexican Navy, a U.S. Coast Guard lieutenant said Saturday.

Even though the 32-foot Pelican was located around 8 p.m. Friday, there's still no word from either Josh Hartman, 28, or his fiance, 30-year-old Ana Martin, Coast Guard Lt. Jeremy Denning said.

Hartman and Martin left Oceanside Harbor about 7:30 a.m. Thursday and were reported missing 13 hours later. The couple is scheduled to wed in August.

The U.S. Coast Guard has inspected the waters off San Diego County with a helicopter and fixed-wing aircraft, but the search has been suspended, according to Denning.

Odds of survival in the cool waters off the U.S. shore "are slim" at this point, the lieutenant said.

If they're to be found alive, the greater probability is that they would be off Baja California near where the Pelican was beached, an area the Mexican Navy continues to search, Denning said.

Hartman reportedly called family members Thursday afternoon to say they were fishing off Camp Pendleton and getting ready to return to port. He's been described as an experienced boater and fisherman.

Martin reportedly began helping him on the Pelican just this week.

Reports that the boat did not have the proper radio equipment are incorrect, Denning said.

The boat washed ashore about 60 miles south of Camp Pendleton, and 15 miles south of the border Friday night, and word of the beaching reached the Coast Guard after a Tijuana television station broadcast news of it, the North County Times reported.

Denning said the condition of the boat is unknown, but a life raft is still intact.

The Mexican Navy has towed the vessel to a marina in Ensenada, where a U.S. Coast Guard investigator could inspect it.

"The assistance provided in the past two days by the Mexican Navy has been outstanding, and greatly appreciated," said Cmdr. Daniel LeBlanc, the acting head of the U.S. Coast Guard in San Diego.

To reach Rosarito, the Pelican would have had to have drifted past San Diego in coastal waters patrolled by the Department of Homeland Security and Coast Guard, and plied by dozens of recreational and commercial fishing boats on a routine day.
