Rolls-Royce Marine has launched a new waterjet for naval markets. The Kamewa FF67 will be the latest in the FF-series of aluminium waterjets, which are the lightest and most powerful in their power range.
The new waterjet, available from late 2009, will also be suitable for commercial marine and offshore markets.
Rolls-Royce Marine, which pioneered the application of waterjets in naval vessels, said the FF67 is an entirely new design incorporating built-in hydraulics for the first time. This will save installation time at shipyards and guarantee smooth start-up.
At high speeds, the unrivalled efficiency of waterjet propulsion offers either a greater top speed or better fuel economy. No reversing gearbox is required, stopping distances are short, and the craft can turn on the spot or even manoeuvre sideways.
"The FF67 is suitable for a range of vessels, including large naval boats, fast ferries and crew boats," said Jay Dagher, Area Manager, Naval, for Rolls Royce Marine (Middle East and South America).
The waterjet's lightweight design is achieved through a combination of an aluminium frame and an inlet duct manufactured from welded aluminium sheet.This production method also gives improved anti-corrosion characteristics and allows the waterjet to be customised to meet customer requirements.
