W6YNK/MM 1949
The operator was Howard A. Wood W6YNK - MM m/s Christer Salen, off Shanghai, China, in QSO with ZC1AZ in Transjordan, in 1949.
On February 15, 1951 the M/S Christer Salen, one day out of Yokohama, bound for Vancouver, B.C., was proceeding at a speed of approximately 12 knots into a heavy sea, when without warning and for no apparent reason she suddenly split in two at about the middle of No. 3 hold. The forward part, after being jammed by a sea into the after part, floated off and sank with the consequent loss of all cargo therein. The after part returned without incident to Yokohama. The cargo in No. 4 and No. 5 holds sustained only slight damage.
There is an interesting article on the internet about the subsequent legal proceedings following the incident. Interesting reading. http://law.justia.com/cases/federal/appellate-courts/F2/258/901/412311/
