Vessel Type

Wooden propeller steam tug, designed for towing and dredging operations.

Description

Description

The Tacoma was a wooden-hulled propeller steam tug, powered by a double expansion steam engine driving a single screw. She carried a Scotch boiler, rudder with quadrant, and heavy towing bitts for dredging and harbor work. Measuring just over 73 ft, she was considered small but robust, intended for towing scows and dredging equipment in and around Chicago Harbor and the nearshore Lake Michigan coast.

History

History

Built in 1894 by E.W. Heath at Benton Harbor, MI, the Tacoma joined the fleet of Fitzsimmons and Connell Dock & Dredge Co. of Chicago. For 35 years she served as a dredge tug and harbor assistant. During her career she became the oldest active tug in Chicago by 1929, outlasting many contemporaries as steel replaced wood in harbor tug construction.

She towed scows, assisted dredging operations, and performed general harbor work. Despite her age, she remained in constant use and was well known among Chicago’s maritime community.

Significant Incidents

Significant Incidents

Final Disposition

Final Disposition

On November 4, 1929, the Tacoma was towing two scows from Chicago to South Chicago, three-quarters of a mile south of the 68th Street crib, when she sprang a serious leak. The six-man crew released the towing cable and scrambled aboard one of the scows before the tug went under. They were later rescued by a Jackson Park Coast Guard surf boat. The tug sank in about 30 ft of water near Clark Shoal, 2.66 miles from Calumet Harbor Light at a bearing of 343°.

Current Condition & Accessibility
