Putting this year's other launches firmly in the shade, Somnio spans a colossal 728 feet (222m), making it the largest superyacht ever built.
The world's first "yacht-liner", this $600 million (£470m) floating palace for the mega-rich is billed as "the most exclusive address in the world" and will cruise the planet's iconic yachting destinations, from Monaco to French Polynesia.
Somnio features 39 luxe private residences and a wealth of "six-star" amenities, including an enormous resort-style swimming pool, premium spa, opulent cinema, gourmet restaurants, 10,000-bottle wine cellar, and a library.
