High-tech fuel and stability solutions for Bray's new 42m superyacht

21 July 2011

Bray Yacht Design and Research has used cutting-edge hull features to increase fuel efficiency and reduce pitching in its new 42m project.

‘These features combined with our hull form produce a vessel that is 30 per cent more fuel efficient than most, has higher comfort levels as it pitches less, and has protected stabiliser, props, and rudders for serious global cruising,’ says Patrick Bray, naval architect for the vessel.

The motor yacht has been fitted with a bow bulb, which company tests have shown lowers fuel consumption by 12 to 15 per cent and significantly reduces pitching.

The semi-displacement hull also features mid-ship and stern bulbs. These are still in the early stages of development, but when optimised Bray estimates they will offer a reduction in power requirements of 6 and 7 per cent respectively.

The Canadian company will also fit a robust stabiliser system that has been tested in the Arctic and add bi foils under each propeller, to reduce stern trim and pitching.

The yacht will sleep 14 guests and 10 crew members in luxurious accommodation. She will feature twin 1,000hp diesel engines offering a cruising speed of 12 knots and a top speed of 16 knots.
