Construction Onoko (Official number 155048) was built at Radcliffe's yard in Cleveland by the Globe Iron Works Company and was launched on February 16, 1882. She had a length of 302.6-feet, a beam of 38.6 feet and a height of 24.8-feet. She was powered by a 900-horsepower
compound steam engine fueled by two
Scotch marine boilers, and gaff-rigged with auxiliary sails on four masts. She was commissioned by Phillip Minch of
Vermillion, Ohio, for the Minch Transportation Company of the Kinsman Steamship Company and a syndicate of other investors. opened in 1881 when the new
Weitzel Lock was built at
Sault Ste. Marie, Michigan.
Onoko capacity to carry oats was believed to be at around 155,000 bushels. The
Buffalo Courier provides an accurate account of when
Onoko arrived in Buffalo. It said that "About noon on Saturday the new iron steamer
Onoko arrived here with something over 88,000 bushels wheat. She left Chicago last Tuesday at 4:20PM and her time in coming down was three days and nineteen and a half hours".
Onokos wooden spar deck was replaced with steel in 1901. Later that year the principal owners of
Onoko, the Nicholas Transportation Company, bought out all the lesser stockholders to become sole owner of
Onoko.
Onoko had steel aft cabins installed in 1907 through 1908. In 1910, Captain Harry Stewart was appointed as the master of
Onoko. On the night of December 1, 1910,
Onoko ran aground on Southeast Shoal during a snowstorm 60 miles below
Amherstburg, between
Point Pelee and
Wheatley, Ontario. She was released with three tugs, including
Harding and
Rescue, that were sent to rescue
Onoko. She was carrying coal at the time. On December 2, 1910, the
Duluth Herald wrote an article saying
Onoko was not in any serious danger. The tugs succeeded in refloating her without serious damage to her hull. On October 7, 1912,
Onoko sprang a leak and was intentionally beached in the
Apostle Islands. The cost to patch her hull was minimal. ==Sinking==
