Briggs Marine's miscellaneous workboats of all shapes and sizes are often seen on the Clyde. This vessel, FORTH GUARDSMAN, was acquired by the firm in 2003. She was built, as ARCTIC IGNIK, in Japan for Canadian owners for use in Arctic waters. With a bow ramp, since removed, she served in Canada until 2001, by which time she had been renamed RUPERT RIVER before crossing the Atlantic to join the Briggs fleet. More recently, FORTH GUARDSMAN has been employed laying submarine cables. She is 50 metres in length, and has a deadweight of 772 tonnes. Propulsion comes from twin Cummins diesel engines, driving two retractable hydraulic drive units. When photographed at 'Bravo 4' anchorage, she had just arrived from Burntisland in Fife and was waiting to head upriver to load equipment.
