The Jones Act quali? ed vessel, measuring 639 feet in length, 78 feet in beam, 45 feet in molded depth and 28,000 dead weight tons, will transport raw materials traditionally carried by lakers such as salt, iron ore and stone to support manufacturing throughout the Great Lakes region. And it has also been thoughtfully designed in preparation for the new cargoes of the future.
“If you toured the ship, you may have noticed in many re- spects that it is very different than a traditional Great lakes self-unloader. This is intentional as we made unique changes to the design of the ship so that it could be more versatile and
