Dunlap Towing receives new tug from Hansen Boat Company

Dunlap Towing has taken delivery of Sigrid Dunlap, a tug built by the Hansen Boat Company.

The tug, as well as its sister ship Phyllis Dunlap, was designed by Hockema Whalen Myers Associates.

The 37-metre long, 11.6-metre wide, 5.5-metre deep new vessel will be put to work towing container barges from Seattle to Honolulu on a scheduled service for Alaska Marine Lines.

The vessel is ABS and SOLAS classed with an ABCU endorsement for unattended machinery room operation. Redundant controls and monitoring equipment ensure the most automated and reliable platform possible.


The vessel is fitted with twin Caterpillar C175-16 engines turning at 1,600rpm that meet EPA Tier 3 and IMO Tier II standards.

On deck, the vessel is fitted with a large double drum Markey TDSDS-36 tow winch on the aft deck and an electric Markey DESW 32-20 hawser winch with anchor windlass on the bow. The tow pin unit was provided by McEvoy Machine.
