Made by Silveryachts, the Silverfast completed a voyage from Australia, where Silveryachts is based, to Europe, a journey of almost 10,000 nautical miles, with just one fuel stop, a feat near-unprecedented for a large yacht.
In good conditions, Silverfast can cruise at around 20 knots (23 mph) and includes a night-time mode - a "quiet and vibration free" ride, according to Silveryachts - that slows the speed down to 18 knots (20 mph). To achieve this, Silveryachts included "quantum zero-speed stabilisers" that also keep the yacht still at anchor.
Beyond all of the eco-friendliness, Silverfast includes nine guest cabins (a master suite, five doubles and three twins), can house a crew of 18, has a maximum speed of 27 knots (31 mph), and has a sun deck with an outdoor cinema, an eight-person Jacuzzi and 70,000 watt sound system.
Of course, the yacht is no good for getting to shore, and so Silveryachts included a tender stowage area accessible via "gullwing doors" - like those of a Lamborghini - and a helipad.
Here's what the Silverfast looks like.
