About Us

As the largest privately held U.S.-flag fleet on the Lakes, Interlake has been carrying the bulk cargoes that have been fueling the region's economy since its founding more than 100 years ago.

A second-generation, family run company, Interlake is propelled by a long-term vision to make its fleet of nine vessels the most efficient and environmentally responsible in the shipping industry.

Led by President Mark Barker, the company has invested more than $100 million to modernize and improve its ships to safely and reliably transport 20 million tons of raw materials annually, including iron ore and fluxstone for the steel industry, stone for the construction industry and coal for power generation.

Interlake employs about 400 men and women who live and work in the region and the cargoes they deliver help generate and sustain more than 103,000 jobs in the eight Great Lakes states.

We know shipping matters, today, tomorrow and in the future...

...and we're in it for the long haul.
