After months of extensive testing, the world’s tallest luxury superyacht – known as Sailing Yacht A – has begun its sail from Germany to its new owner, billionaire Andrey Melnichenko, in Russia.

The $450 million yacht features three carbon fiber masts that are each nearly 300 feet tall. Daily Mail reports that the masts are the largest freestanding composite structures in the world. CNN added they are the largest of any yacht and are able to withstand twice the weight of a commercial Boeing Dreamliner wing. In North America, perhaps the closest structure that matches that magnitude is Apple’s “Campus 2” – which features the largest freestanding carbon fiber roof.

In addition to the strength it receives from carbon fiber, the yacht is encased in bomb-proof glass and features 40 security cameras. The yacht’s 468-foot-long hull is made primarily with steel, but it also incorporates carbon fiber to keep the superstructure’s overall weight down.

The yacht has eight decks, a helicopter pad, a huge pool, and an underwater observation area. It is powered by a “hybrid diesel-electric package with controllable pitch propellers,” and is designed to accommodate 20 guests and a crew of 54. Each diesel engine produces 4,800 horsepower, while the two electric motors are rated at 4300 kWh each. Due to its size, Sailing Yacht A has a cruising speed of 18 miles per hour and has a maximum speed of 24 mph.

The yacht is expect to arrive in Russia later this spring. To see it in action, check out the video below:
