Warren, R.I., shipbuilder Blount Boats reports that, on Friday, August 28, the 56-foot, twin-screw tug Breaker II completed its delivery voyage to the Robert Moses Niagara Power Plant, operated by New York Power Authority.
The 56- by 18.5-foot shallow draft tug was designed by the Bristol Harbor Group of Bristol, R.I., and has a reinforced hull for breaking ice efficiently. It will operate in seasonal ice near the entrance to and within the upper Niagara River.

This is the first Subchapter M certified vessel built at the Blount shipyard and its hull, machinery, electrical systems and safety equipment all comply with the requirements of USCG Subchapter M – Towing Vessels.
The vessel is powered by two Caterpillar Tier III series C-9 engines, each producing 375 HP @1800 RPM.
Ship’s service power comes from twin Caterpillar Tier III C2.2 marine generator sets, each rated at 27eKW @1,800RPM .
Steel hull plating thickness’ range from 3/4 inch, 5/8 inch and 1/2 inch with 1 inch and 2 inch thick skeg plates. Ice Belt plating and plating to 1/3 abaft of the stem is ABS Grade “D” including the 1 inch and 2 inch skeg parts. All other plating is ABS Grade “A” steel.
