The M/V Iyanough will be out of service at least through Thursday while our engineering and maintenance staff works to repair a small, 5-inch crack on the port side of the vessel's aluminum hull. The crack was discovered Tuesday night following the end of the vessel’s operating day during a routine inspection by our engineering staff. The crack is approximately 4 feet above the water line to the stern of the vessel. It is believed to be a stress crack and not the result of an allision or any individual event.

For safety reasons the vessel cannot run until repairs are completed. The vessel is currently at Fairhaven Shipyard, and we are working with the U.S. Coast Guard to develop and carry out a repair plan. We will provide more detail on the timeline for the vessel’s return to service when we have more information.
