Last year we provided readers with the first images of the US$15 million Adastra superyacht being constructed in China. The incredible watercraft has since traveled 4,000 nautical miles (7,400 km) through the Philippines, Indonesia and Thailand and earlier this month was presented with the 2013 World Superyacht Award for Most Innovative Design.

Designed by John Shuttleworth, the 42.5-m (139-ft) yacht was launched April 11, 2012 from China for clients Anto and Elaine Marden. The futuristic superyacht, which is one of the largest of its kind, features a distinctive trimaran shape. It can consume as little as 17 liters (4.5 US gallons) of fuel per hour when traveling at 10.5 knots, and can be controlled with an iPad.

"Her slender hulls and streamlined exterior allow her to travel faster in the open ocean and at 17 knots she has a 4,000 mile range so can comfortably cross both the Atlantic and Pacific oceans at high speed," says Shuttleworth. See our previous coverage of the Adastra for more on the spec.

Alongside Adastra, other 2013 World Superyacht Award winners included Loretta Anne built by New Zealand based Alloy Yachts, which won Motor Yacht of the Year. This 47-m (154-ft) yacht was also awarded Best Raised Pilothouse Semi-displacement Motor Yacht.
