On April 19, Hong Kong-based superyacht builder held a keel-laying ceremony at the company’s production yard in Zhongshan, China. Kingship has garnered plenty of press recently, with one of its 2010 releases, the Columbus 90 Belle Isle, which was purchased by a Hong Kong businessman and based in the Mediterranean.  The company’s 144-foot Green Voyager concept was developed and announced at the 2009 Monaco Yacht Show, with first steel cut in the latter half of 2010. The yacht, which means RINA’s Green Plus requirements and is designed for long-range, independent cruising with low carbon emissions, is a model of efficient running.

Green Voyager is a revolutionary new design concept that combines luxurious comfort and environmental responsibility. It is for the owner who seeks a low impact motor yacht to cruise the globe; one who wants to do so responsibly but doesn’t want to compromise on luxury and comfort.

Kingship, Axis Group Yacht Design of Viareggio, Italy and Big Blue Consulting Limited have been adopting various design solutions, choosing a hybrid propulsion system, onboard equipment and defining operational procedures to ensure Green Voyager is the most energy-efficient and low emission yacht. It is complying with the yacht under the 500 GT rules and achieving RINA’s highest level of notation, Green Plus Platinum.

With this certification, the Green Voyager will be free to cruise in some of the most sensitive environmentally sensitive areas. A plumb (vertical) bow extends the waterline length until it is only 50cm shorter than the yacht’s overall length, producing very low underwater drag. As confirmed by tank testing this hull form uses the minimum of fuel and offers increases propulsion efficiency of 16-18%. A radical wastewater treatment plant means that the yacht has zero discharge, other than drinkable water. Energy demand is reduced and energy that is created is stored when not used. Solar panels are incorporated as are a powerful battery bank for silent running at six knots for up to three hours.

The Green Voyager is projected to have a top speed of 16.5 knots, and under diesel electric power at cruise speed burns just 50 litres per hour.
