In 1932, a small, relatively insignificant towboat was launched at East St. Louis, ill., by the St. Louis Structural Steel Company. It had a steel hull of 64 by 15.5 by 5.5 feet with a tunnel stern. It was a single-screw vessel powered by a six-cylinder direct-reversing Kahlenberg diesel that had a variable horsepower rating of 150-180. The propeller was also manufactured by Kahlenberg, and, according to an ad in The Waterways Journal, it was of the "heavy steel towing type with 56-inch diameter." The Kahlenberg ad also claimed that the boat would have a "pool water speed" of 10 mph. at 340 rpm. It is assumed this would be a light-boat speed. |
