Rolls-Riva: New eco-fuel for yachts.

Rolls-Royce has been planning another venture into luxury yachts. Last time it got into a deal with Riva, bought by its then-owner Vickers for £9.1 million but it didn’t survive the 1998 change in proprietorship. Then last November Rolls-Royce announced the 62metre Crystal Blue with hybrid propulsion using LNG (Liquefied Natural Gas) and battery power. This is planned to have a composite or aluminium hull and Rolls-Royce’s hybrid LNG/battery SAVe-CUBE system. This has twin 16V4000 MTU M65-N generator sets working in parallel with a battery bank providing 1MWh of genset-free power in port. Two light-weight carbon Azipull thrusters provide a maximum service speed of 20 knots.
