The harbor tugboat, built in 1961, was transferred from Portsmouth. The Chock and its crew of eight will be used for homeland security patrols, law enforcement and ice-breaking in the upper bay. It also will continue to be used in the lower bay.
Capt. Mark O'Malley, the Coast Guard's captain of the port of Baltimore, called it "a privilege" to add the cutter to the Curtis Bay operation, noting its "long history of superior service to the mariners of the Chesapeake Bay."
Baltimore's Coast Guard station responds to more than 200 search-and-rescue incidents and conducts more than 370 law enforcement boardings annually.
