The 73 ton fishing vessel Hsiehyi No. 6 has gone missing since last making contact on September 8, 2011.   The Hsiehyi No. 6 was last reported fishing some 350 miles southeast off Okinawa, Japan.   Typically, the fishing vessel would contact the owners once per week.   A strong typhoon in the area has prevented any search by authorities to be conducted.    Owners have contacted other fishing vessels in the area to conduct a search for the missing vessel.   The Hsiehyi No. 6 was reported to have eight men on board.
