Canadian designed Canadian built

Unlike the US where the Jones Act mandates that commercial vessels be built in that country, Canada allows vessels built anywhere to work in Canadian waters.

The marine press has carried stories of China-built hulls finished out in Canada. At the same time, the trade press has carried multiple stories of Canadian-designed tugs built in countries throughout the world. The 13.21-metre 'Inlet Wrangler', built by Mactavish Welding and launched in December at Campbell River on Vancouver Island, was the first BC built tug in eight years. The boat is also Canadian-designed in BC by naval architect A.G. McIlwain who has also designed tugs for New Zealand and Australia. Owned by Glenn Wheeler's Gowlland Towing, the boat will be primarily used in towing logs from up-coast logging operations to south coast mills. The boat's deep hull (3.17-metres x 6.1-metres) gives her great stability while keeping her props in solid water. Harris and Robbins of Vancouver supplied the towing winch. A pair of Cummins KTA19 M3 engines each generating 373kW at 1800 RPM provide power for the boat's nine-knot free running speed and an estimated 39,000-pound bollard pull. The engines turn 1.6 x 1.3-metre four-blade propellers in nozzles on six-inch shaft supplied by V.M. Dafoe Machine Shop also of Vancouver. The gears are Twin Disc model 5222.
