Barnstable fire crews used two booms to create a 300-foot diameter perimeter around the boat to contain the spill. Absorbant pads were also used to soak up the fuel.

At a press conference this morning, Barnstable Fire Chief Francis M. Pulsifer said they do not yet know how much fuel was leaked into the harbor. Pulsifer said the leak was minimal compared to the boat's 300-gallon tank.

Boat traffic was limited in the harbor during the salvage operation. 

Officials don't know caused the boat to sink.

Boat U.S. is the salvage company investigating the incident. Divers with the company are securing the fuel tank and will use inflatable booms to lift the boat and remove it from the water.

No one was on the boat when it went down.

The Environmental Protection Agency and the boat’s owner were informed of the incident.

Volunteers from the Cape and Islands American Red Cross were called to the scene to assist first responders.
