Saltchuk Resources has continued to fatten its holding in New York-listed Jones Act operator Overseas Shipholding Group.
The Seattle-based conglomerate has bought more than 367,000 shares in the past six weeks.
The buys have pushed Saltchuk's stake in Sam Norton-led OSG to 16.8%, up substantially from when Saltchuk first revealed it had bought a large piece of the Florida company just over a year ago.
