Built in 1977 by Ailsa Troon, Isle of Cumbrae is the oldest member of the CalMac fleet as of 2020.
Originally built with 2 x Gardner 8L3B engines she was re-fitted with twin 230hp Scania D9 units in 2002.
Electrical power is provided by either one of the two Lister HRW3 generators of 32hp fed to a very basic distribution board in the port-aft side of the engine room.
Propulsion comes from two Voith Schneider Lochalsh III units each driven via a Twin Disc reduction gearbox and Fluidrive viscous coupling.
Due to her age, and relative difficulty in sourcing certain spares it is expected that she will be retired from the fleet in the next few years.
