For their latest superyacht concept, Lazzarini dreamed big. The 328-foot long Saturnia features 5 stories, plus an additional antenna area on the top with a hexagon-shaped pool. Along with ample deck space and an additional pool, its upper level also includes two slide-out lounge areas with glass floors. A walkable deck wraps around the vessel and leads to a pair of automatic gates. When opened, the center of the boat turns into a harbor to dock the tender and other water toys. Its interior can be arranged to accommodate 10 to 20 guest suites, as well rooms for 20 crew members. Although it's substantial in size, the ship's body is made entirely from dry carbon, making it 50 percent lighter than other yachts of the same size to reach a top speed of 30 knots.
