The sinking of two vessels being towed in Massachusetts bay in 2018 was likely due to a decision by a tow captain and vessel owner to attempt a transit in wind and waves “that exceeded their original plan for the voyage,” according to a report issued by the National Transportation Safety Board (NTSB), which investigated the incident.

Two crew members received minor injuries in the December 2 incident, which occurred while the towing vessel Big Jake was towing five barges and two workboats. A tow broke apart, causing the barge Dredge200 and the workboat R.E. Pierson 2 to sank.
