This articulated tug was built in 1976 by Halter Marine in Pierre Part, LA as the Andrew Martin for AMT Marine. She was renamed Robert L. Torres in 1990. In 1991 her original Stork-Werkspoor engines were removed and replaced with two Caterpillar 3608 diesels. In 1994 she was renamed Jacklyn M. In 1996 she was purchased by LaFarge North America, who rebuilt the tug with a raised pilothouse, and added a Bludworth coupler system to make her an articulated tug. She entered service on the Great Lakes in 1997 with the cement barge Integrity. In 2002 the Jacklyn M. was repowered yet again, this time with two EMD 20-645 engines. In 2004, she was renamed G.L. Ostrander.

G.L. Ostrander operates for LaFarge out of Alpena, Michigan on Lake Huron, and visits Lakes Michigan, Superior, and Erie regularly with loads of powdered cement.

  1. Does this tug have conventional stern propulsion with or without rudders, or are the two propellers ducted and w/ or w/o rudders? Need this information for a propwash analysis.

  2. One more question – what is the distance between the two stern props or distance from tug centerline to prop center? We need this info for propwash analyses for the Lower Fox River. Thanks
