RMAS Fiona was a Felicity-class water tractor, built in 1973 by Hancocks. She displaced 80 tons, and was powered by a single Voith-Schneider propeller which generated 600 bhp and gave her a maximum speed of 10 knots. In 2007, she was placed on the Ministry of Defence Disposal Sales Agency website for £70,000. Sold to Macrae Marine. Quoted from Wikiwand

In the UK, when “RMAS” precedes the name of a boat, it stands for the Royal Maritime Auxiliary Service. This was a British Government agency that operated a variety of auxiliary vessels for His Majesty’s Naval Service, which includes the Royal Navy, Royal Marines, and Royal Fleet Auxiliary. Since 2009, the service has been run by Serco and is known as Serco Marine Services. RMAS vessels carried the ship prefix "RMAS". (A.I.-Generated Article).
