Wednesday Beijing time, Guo's vessel was found about 620 miles northwest of Hawaii's main island of Oahu. The airborne search team did not see Guo on deck, but the main lateen sail of the 97-foot trimaran was broken off in the water. The Coast Guard sent an HC-130 Hercules, a long-range surveillance and transport aircraft, to the area where Guo's vessel was sending a location signal. The crew tried to communicate with Guo via wireless walkie-talkie, but failed. Two rescue vessels have been sent by the US Navy and crews will access and board Guo's vessel to investigate, according to the Consulate-General of China in Los Angeles.
