Main propulsion for the Capt. Jim McAllister will come from twin Caterpillar 3516E, Tier 4 diesel engines producing 3,386 hp at 1,800 rpm each. The Cats connect to Schottel SRP-4000 fixed pitch Z-drives in drop-in tubs.

Ship’s service power will come from three Cat C7.1 turbocharged gensets, sparking 118 kW of electrical power at 1,800 rpm each. Firefighting apparatus are powered by a Cat C 9.3 Tier 3 auxiliary diesel engine connected to a Fire Fighting Systems FSP 150×200 fire pump and an FFS 300M monitor, pushing 3,000 gpm.

On deck will be a Markey Machinery series DEPF-42-40 towing winch, stern mounted and a Markey DEPCF-52-75 hawser winch, bow mounted.

The new tug will be ABS Maltese Cross A1 Towing, Escort, Maltese Cross AMS, Ice Class “DO” (but without ABS notation), EPA Tier 3 and Tier 4.

The Capt. Jim McAllister (ESG Hull #223) is from the same 100′ Z-drive tug design provided by Jensen Maritime Consultants, Seattle, as the previous three tugs. The Rosemary McAllister (ESG Hull #224) was delivered in June 2018 and in final outfitting is the Ava M. McAllister (ESG Hull #222), each constructed at the Allanton facility.

The Rosemary McAllister was honored as one of the Significant Boats of 2018 by WorkBoat magazine. The lead vessel of the four-vessel series is the Capt. Brian McAllister which was delivered in 2017 and built by Horizon Shipbuilding Inc.
