Two Cummins-Powered Boats Building at Utica, Indiana Yard

Marine Builders of Utica Indiana are nearing completion of two Cummins-powered vessels.

M/V SIR WINSTON

A 90- by 30-foot steel-hulled dinner cruise vessel for the Florida market will be delivered in early August for owner Winston Knauss of Ft. Lauderdale. Designed by DeJong and Lebet of Jacksonville, Florida the 400-passenger vessel is powered by a pair of Cummins 6CTA 8.3-M engines producing 300 hp at 2500 RPM. The engines will turn four blade 30X27-inch propellers through ZF 300C IRM 301 A-2 gears with a 2.91:1 ratio. Designer Andrew Lebet says, "This is the third vessel that we have designed for that company with the same power package and the second from Marine Builders."

The new boat has a pair of Cummins/Onan 95 kw gen sets and a 76 hp Cummins 4B3.9M powered bow thruster. "Hydraulics whine, they don't work right, you need to make sure you have the right generator up and running," explains Lebet or the bow thruster, "If a diesel engine will fit we prefer to use that."

The Sir Winston has crew accommodations and a galley capable of serving the guest with an elevator to move people and food between decks. "The boat is one of the first to be approved under Subchapter "K" of the U.S. Coast Guard," says Lebet.

ST. LAWRENCE SEAWAY CORP. TUG

"It is a good looking little tug," says Bill Preston of Pensacola-based Marine Design of the boat building to his drawings at Marine Builders in Utica, Indiana. The 50X16.5-foot tug boat will be responsible for moving a barge in service to navigation aids for the St. Lawrence Seaway Corp. Slated for an August 30 delivery date, the boat will be powered by a pair of Cummins NTA-855 diesels delivering 270 hp each to a pair 46X30-inch four-bladed props through Twin Disc MG-5091 3.82:1 gears.

Interior spaces of the heavily constructed steel hull and cabin will be served by a hot water heating system. For river use the boat will be equipped with water lubricated composite-type Thordon rudder and shaft bearings. A general arrangements drawing is available from the designer.
