It’s been almost four decades since a new bulk carrier ship joined the Great Lakes fleet, a hiatus broken last Thursday after workers opened the valves to flood the dry dock at Fincantieri Bay Shipbuilding in Sturgeon Bay to launch the Mark W. Barker. “This is a huge milestone for all of us to be able to put the boat in the water for the first time,” said the vessel’s namesake, Mark Barker, president of Interlake Steamship, which commissioned and owns the ship. The 639-foot-long, 75-foot-wide bulk freighter received full maritime honors Oct. 28, including a large crowd, speeches and the crack of a ceremonial bottle of champagne against the bow of the ship above the vessel’s nameplate.

SAULT STE. MARIE—In hard hats and safety vests, the two women shimmy up aluminum boarding ladders onto a converted World War II tanker.

⚓Launching the M/V Mark W. Barker⚓

Launch of the First U.S.-flagged Great Lakes Bulk Carrier in Nearly 40 years

Fincantieri Bay Shipbuilding and The Interlake Steamship Company hosted a launch ceremony Oct. 28, marking the latest milestone for the new 639-foot M/V Mark W. Barker.

The first U.S.-flagged Great Lakes freighter to be built on the Great Lakes in nearly 40 years, the M/V Mark W. Barker – while still under construction – was “launched” or otherwise floated in the water in the large drydock at the Sturgeon Bay shipyard.

A formal maritime tradition, a launching ceremony honors the first time a boat is transferred from land to water. The public event is a way of celebrating and blessing the new ship and its crew to bring it good fortune on its future voyages.

“Today is truly gratifying for our company to commemorate the first time the completed hull of our new ship has touched water,” said Mark W. Barker, President of The Interlake Steamship Company and namesake of the new vessel, which is the first new ship constructed for the maritime company since 1981.
