Washburn & Doughty Associates has delivered the tug Mary McAllister to McAllister Towing, the latest vessel in a seven-ship series built in Maine.
MarineLink Maritime News reported on 25 September 2026 that the transfer took place at the builder's yard in Maine, with McAllister Towing taking receipt of the vessel from Washburn & Doughty Associates, Inc.
Series and certification
Mary McAllister is the sixth unit in a seven-tug series that has been built to meet American Bureau of Shipping classing and certification standards; the series is described in the report as consisting of tractors rated at an 84-metric-ton bollard pull. The boats in this run are characterised in the report as low-emission tractor tugs, a detail that the builder and buyer have highlighted in the announcement covered by MarineLink Maritime News.
Delivery of Mary McAllister continues a sequence of handovers within the fleet programme and adds to McAllister Towing's contingent of ABS-classed tractor tugs, according to the published account. The reporting makes clear that this unit is one of seven sister vessels sharing the same classing and bollard-pull specification.
Remaining hull in the series
With Mary McAllister identified as the sixth of seven, the series will comprise one further sister tug after this delivery, leaving a single hull outstanding from the seven-vessel order. The report does not offer further schedule detail for that final unit but places the latest handover within the wider seven-tug programme noted by the parties.
Washburn & Doughty Associates constructed and delivered Mary McAllister from its yard in Maine, and McAllister Towing accepted the vessel as described in the MarineLink Maritime News item dated 25 September 2026. The account supplied to the trade outlet states the key technical and regulatory descriptors for the series, including American Bureau of Shipping classing and certification and an 84-metric-ton bollard-pull rating, together with the low-emission designation.
The delivery of Mary McAllister completes another stage of the seven-tug production run between Washburn & Doughty and McAllister Towing, as recorded in the MarineLink Maritime News report of 25 September 2026. The announcement identifies the tug by name, its place in the seven-vessel series and the principal classing, bollard-pull and emissions characteristics that define the group.
