Washburn & Doughty, East Boothbay, Maine, recently delivered the 93'x38' tug Grace McAllister to New York-based McAllister Towing.
Main propulsion comes from two Caterpillar 3516E Tier 4 engines producing a total of 6,770 hp that power twin Schottel SRP 490 Z-drive units, giving the tug a bollard pull of 85 metric tons.
Combining her eco-friendly Cat engines with Markey Machine winches on the bow and stern makes the U.S.-built Grace one of the most advanced and powerful shipdocking tractor tugs serving the Port of New York, said McAllister. The Grace joins a fleet of certified low emission vessels, including the Ava McAllister and Capt. Brian A. McAllister in New York.
This year marks the 160th year of maritime operation at family owned McAllister Towing.
