The Clarke was the first of three AAA ships built for the Pittsburgh Steamship Company in 1951. She was named after a banker who was a member of the board for US Steel. She was originally built as non-self unloader.
Originally she was 647 feet long and could carry 20,300 tons of cargo. She was powered by a 7000 horsepower engine and could travel at 16 mph. At the time she was one of the most modern ships afloat on the lakes.
She was the first ship to use the modernized Poe Lock. She's also been the first ship down the locks for the season a number of times. One time her anchor found a boat that had been missing for 5 years.
I kind of wish she were closer because she seems like a nice ship.
