In the late 60s, the yard also made oil rig supply vessels and salvage vessels.
1970s The key work of the yard during the 70s was a series of stern trawlers for the Ranger Fishing Co. This led on to trawler work for Norwegian and Icelandic companies.
In July 1977, the yard was nationalised, and became part of British Shipbuilders. Work was started on a naval coaster training craft of the "Archer" class.
In 1985 the yard's own management team successfully made a private buy-out. Unfortunately the following year, a lack of orders led to the yard being closed.
It reopened as a yacht builder in 1987 under the name Brooke Yachts International
