Mermaid Marine supplies engines for MGB 81
Mermaid Marine has supplied three engines for the famous Motor Gun Boat 81 (MGB81).
Restoration work on the vessel is being carried out by Berthon Boatyard with the installation of the new FPT engine currently under way.
The engines supplied are three FPT C13 825hp diesel engines to replace the previous MAN 835hp engines.
The new FPT engines were chosen for their reliability, fuel efficiency, quiet running noise and lighter weight and will enable MGB81 to reach speeds of around 40 knots.
Mermaid Marine has also sourced a complete propulsion package working with other suppliers including Centa Transmissions, Clements Engineering and MIT.
“It’s been a very exciting project to be involved with, especially as MGB 81 is such a historic vessel,” said Mermaid Marine sales executive Julian Osborne. “The FPT engines are very popular within the marine industry providing high torque and power.
“FPT’s engines are known for their reduced fuel consumption and exhaust gas emissions together with reduced maintenance periods and therefore lower operating costs so they will be perfect for MGB81.”
The C13 is a six-cylinder, 13 litre engine.
MGB 81 was originally launched in June 1942 and at the time was among the fastest of her type.
MGB 81 and her sister vessels were involved in action in the English Channel, attacking enemy torpedo boats and landing secret agents on occupied soil.
She was later involved in D-Day operations. She will be the only restored and operational example of a Royal Navy Coastal Forces MGB that saw active service in WW2.
The restoration and engine contract was awarded by Portsmouth Naval Base Property Trust that will show MGB 81 at the Portsmouth Historic Dockyard alongside vessels such as HMS Victory, HMS Warrior and the Mary Rose.
The engine room package included Twin Disk gearboxes, shafts and prop, fuel tanks, 240v generator, batteries and fuel tanks. Work on MGB 81 will also include a new exhaust system, fuel system and seawater cooling system.
