RJ 301 Catriona
New 1/1250 scale waterline model of the Caledonian MacBrayne ferry Catriona as in 2016 by Rhenania Junior (RJ 301).
One of three ferries in the world to use diesel electric hybrid power. Two diesel generators feed power to a 400 volt switchboard which supplies power to the electric propulsion motors. In addition she has two lithium-ion battery banks with a total of 700kWh that can drive the engines. The batteries are charged overnight from land based power using renewable energy sources. This combination reduces fuel usage by 38%.
She is 150 feet long, 150 passengers and 23 cars. Service speed of 9 knots. Currently operates on the Claonaig - Lochranza crossing.
