James L. Kuber is a self-unloading articulated barge owned by Rand Logistics and operated by Grand River Navigation.

It was powered by a Westinghouse Electric Corp cross-compound steam turbine engine and two Foster-Wheeler water tube boilers.

In April 1990, during heavy snow, the Reserve ran aground in the St. Marys River while carrying a cargo of ore from Duluth, Minnesota to Toledo.

After repairs took place, Oglebay Norton chose to convert Reserve to an articulated self-unloader similar to her fleetmate Lewis L. Kuber.

After another two months, Reserve arrived at the KK Integrated Logistics dock in Menominee, Michigan for conversion to a self-unloading articulated barge.

Most of the conversions took place in Menominee, but in December the barge was briefly moved to Bay Shipbuilding for drydock.

On March 29, 2008, the new articulated barge was christened James L. Kuber, after the brother of the owner of KK Integrated Shipping.
