The JOSEPH L. BLOCK is Heading to Duluth

April 17, 2025

Tom Wenstadt, our Door County correspondent, reports that the M/V JOSEPH L. BLOCK departed Fincantieri Bay Shipbuilding Wednesday evening, April 16th. The BLOCK went out Sturgeon Bay, up the bay of Green Bay and out into Lake Michigan. The vessel headed for the Straits of Mackinac and ultimately to the port of Duluth, Minn., for its first load of taconite for the season.

The BLOCK was christened June 29, 1976, at Bay Shipbuilding.  The vessel’s name came from the Chairman of the Board of the owner, Inland Steel Co.  She has carried her name though-out her life and has been owned and operated by Indiana Harbor Steamship Co. and Central Marine Logistics Inc. of Highland, Indiana, respectively since July, 1999.  Unfortunately, the JOSEPH L. BLOCK has had a rough career suffering a number of engine problems as well as hull damage from groundings and ice.  However, after 45 years of battling the Great Lakes, the BLOCK continues to serve its owner.  

Specifications:

            Length           728 feet

            Beam (width) 78 feet

            Depth             45 feet

            Capacity        37,200 tons

            Power             2  3600 horsepower EMD V20 diesel engines turning one propeller and bow and stern thrusters

            Self-Unloading rate 6,000 tons per hour

Look for an aft pilot house and an aft self-unloading boom with an iron ore red hull, white upper works and gray accent strips.

Watch for arrivals of the next Fincantieri Bay Shipbuilding winter fleet in December, 2025.
