Built in 2012, by Halimar Shipyard of Morgan City, Louisiana (hull #162) as the Kestrel for Harley Marine Services of Seattle, Washington. Designed by Frank Basile of Entech and Associates of Houma, Louisiana. The tug’s hull design is identical to the Sassafras class tug designed for Vane Brothers of Baltimore, Maryland. With the exception of the raised bow. However, the interior designs differ from the Sassafras class tugs. The Kestrel was designed with the option to be converted to an Articulated Tug and Barge. If the option was exercised the would have a connection system installed in the bow to allow the tug to push a barge from the barge’s stern notch. The point where the barge and the tug connect would undergo powerful stresses. The interior structural elements of Kestrel would have to be reinforced to cope with the additional stresses.
