Chinese mariner Guo Chuan trying to sail on a solo trans-Pacific voyage was missing off Hawaii, his support team said on Wednesday.

All attempts to contact the vessel had failed and a rescue organization in Honolulu has sent a searching aircraft, which found the mainsail in water, broken off Guo's trimaran, but didn't see the sailor on the deck.

Guo was aiming to set a new solo non-stop trans-Pacific sailing world record from San Francisco to Shanghai within 20 days, while the current trans-Pacific speed record is 21 days.

He departed from San Francisco on Oct. 18.
