On April 20, the 30 meter long tugboat Powhatan sank at its berth in Starrigavan Bay near Sitka, Alaska. The Powhatan initially sank in 15 meters of water, but later the tugboat slid further underwater and now rests in 60 meters of water. No reports of injuries, but some oil pollution was released.

Reports state the vessel had some 325 gallons of lube oil and 12 gallons of diesel fuel on board at the time of the sinking. The Coast Guard and local authorities were alerted and responded to the scene. Booms were placed on the surface to contain the pollution. An underwater camera will be deployed to monitor the vessel for any further release of pollution.

There are no reports if the vessel will be salvaged or not.
