The Coast Guard, along with fire departments from Newburyport, Amesbury, Salisbury and Newbury, responded after a boat caught fire and sank in the Merrimack River.
Crews responded for a fuel oil spill on Friday, with pollution response team members working throughout the night to clean up the spill.
The boat, called the Hit List, was salvaged and removed from the water, and reportedly had about 500 goallons of fuel oil on board.
The maximum fuel capacity of the boat was about 700 gallons.
No injuries were reported in the incident, and the causes for the fire and sinking are both under investigation.
