Engine History

The NOAA (National Oceanic and Atmospheric Administration) research vessel John N Cobb is powered by a six-cylinder Fairbanks-Morse diesel engine. The boat, styled after a Pacific Trawler, originally conducted fisheries research in Southeast Alaska every summer as part of NOAA's mission to conserve and manage coastal and marine resources.

In June 2008, the Cobb's Fairbanks-Morse diesel broke its crankshaft, resulting in the ultimate de-commissioning of the vessel. It has since been added to the National Register of Historic places and donated to the Seattle Maritime Academy as a training vessel.
