She was fitted with electric hoists and side-ramps to allow the loading of vehicles from conventional piers and at any state of tide. The 14-ton cargo lift had space for five average cars, which were turned on two 14-foot turntables on the lift and a further one at the front of the "garage". An aft cargo hold had two 7-ton derricks for cargo handling. These were removed in 1958 and the hold plated over, to provide additional car deck area. MV "Cowal" entered service on the Gourock to Dunoon crossing
Highland Boundary Fault Border suggests that rocks along both ends of the fault plane are indistinguishable from one another, with no brecciation. Aligned southwest to northeast from Lochranza on Arran, the Highland Boundary Fault bisects Bute and crosses the southeastern parts of the Cowal and Rosneath Peninsulas, as it passes up the Firth of Clyde. It comes ashore near Helensburgh, then continues through Loch Lomond. The loch islands of Inchmurrin, Creinch, Torrinch, and Inchcailloch all form part of the Highland Boundary Fault. From Loch Lomond the Highland Boundary Fault continues to Aberfoyle, then Callander, Comrie and Crieff. It then forms the northern boundary
