Bow Thruster

  • Michigan Wheel Division, Dana Corporation, recently announced that it will now market a line of bow thrusters under the trade name of Michigan-Jastram. This exclusive arrangement applies to the United States, Canada, and Mexico.

    According to Chuck Dykstra, director of marketing of Michigan Wheel, the company has formed a new propulsion systems group that is consistent with its goal to provide q u a l i t y p r o p u l s i on equipment and systems for improved maneuverability for overall vessel efficiency. Michigan Wheel, Mr. Dykstra indicated, is collaborating with Jastram-Werke of Hamburg, West Germany in manufacturing and marketing of the Michigan-Jastram line of bow thrusters in North America.

    Working with Dr. Dykstra at Michigan Wheel's divisional offices in Grand Rapids, Mich., will be Dave Johnson, propulsion systems manager. Mr. Johnson explains that an essential element of the Michigan-Jastram bow thruster is its high-quality marine gearbox. He adds that since 1954, an ever-increasing number of ships of all sizes and types in Europe have been equipped with Jastram bow thrusters. The Hamburg- based company is a leading European manufacturer of transverse, fixed-pitch bow thrusters.

    In the United States, the Jastram- supplied gears, along with Michigan propellers and transverse tunnels, will provide costefficient thrusters for the North American market.
