In late August this year, Serodino Shipyard at Chattanooga, Tenn., delivered one of its popular Tiger Class 1,200 hp Dinner Bucket Switchboats to the Jeffrey Sand Company
of Little Rock Arkansas. Named Chis M, the new boat was delivered from the Serodino yard on the Tennessee River
up through the Ohio River system to the Mississippi on route to Little Rock. The shipyard now has another of the Tiger Class under construction to be available for order.
The following description of the vessel is provided by the shipyard:
