The Coast Guard in Honolulu is continuing efforts to contact with a Taiwanese-flagged fishing vessel, which deployed its emergency  beacon at 4 a.m. Friday 1,500 miles northwest of Oahu.

The Coast Guard and two ships in the area have been unable to make any contact with anyone aboard the 85-foot fishing boat, the Ming Horng Yu, said Coast Guard spokesman Michael De Nyse.

None of the 11 aboard the boat has responded to radio calls as well as to signals from two vessels who responded to the Coast Guard’s call for help.

Ocean conditions were rough, with seas 37 feet and winds 39 mph, gusting to 49 mph.

The Coast Guard launched two C-130 planes, whose crews successfully dropped emergency data packages, asking the boat’s crew to turn off its beacon, which it did.

On Saturday, one of the vessels, a 623-foot Panamanian cargo carrier, the Amorita, pulled up next to the fishing boat and flashed its lights, but no one responded, De Nyse said. Also an 87-foot-long fishing boat also tried to make contact, but to no avail.
