Hi ken & Dan, thanks for all the infos
4 stackers are sure seldom, I saw a lot 3 stackers on the
Mississippi

Thanks Dan. I live on the East Coast growing up in the Tug Boat Business that my father was in. Always like and still scribe to "Waterways Journal". The Missouri River system seems to be a real challenge for Captains and Pilots. Navigation never has reached the levels of the Other Major River Systems.

Here is an earlier photo ofhttp://www.littleriverbooks.com/photos/Missouri288-14.jpg the Tow Boat Missouri

4xGeneral Motors 12-645E2 diesels, repowered 1973, 5,600 hp.
This boat was built specifically to operate on the Missouri River, which had a designed depth of 6 feet on the upper end. This boat measures 162 x 45 x 10 feet but had an operating draft of only 5.5 feet, with Kort nozzles.

Hi ken
thanks info,, I am often on the mississippi and never saw a 4-stacker there, I was never north of Baton Rouge. That the reason why this one really stuck in my eyes

4 stackers with 4 screws was the maximum HP for the Mississippi River. This tug was built for Federal Barge Line. There are no more 4 screw vessels on the American River System, the Largest Triple Screw delivering upwards of 10,000 HP
