Roseway was built in 1960 in Liverpool, NS by Steel and Engine Products for the (Federal)Minister of Public Works and assigned to the dredging fllet. Usually working out of Liverpool, but ranging up and down the Nova Scotia coasts, it tended a pair of small mud scows and the dredge D.P.W.No. 16 in the maintenance of numerous small harbours. Measuring only 36 gross tons, it was fitted with two engines generating 300 bhp.
As DPW began to exit the dredging scene, the tug was acquired by Dominion Diving in 1989.
In 1991 as it was returning to port it began to take on water and sank just off the IEL wharf in 60 feet of water. The next day (December 24) the tug/workboats Saint M, Little Saint and barge Coneco III lifted the tug off the bottom and moved it alongside the IEL dock. It was then raised by shore crane and taken to Dartmouth Marine Slip. There was very little damage except to the the electricals and electronics, which were replaced. The tug was back in service in 2 months, and later in 1992 was re-powered by Rolls Royce engines totalling 420 bhp.
The tug had provided sterling service as a tug, diving tender, workboat, crew boat, lineboat and any other job that Dominion has had for it.
