This 351-foot concept superyacht has a waterfall, 360-degree glass elevator, and two pools

The Stiletto is not your average superyacht.

Instead, it's a 351-foot floating slice of paradise. Right now, it's just a concept design by Netherlands-based yacht builders Oceanco, but if built, it would rank among the largest yachts in the world.

The amenities include a glass elevator and an unparalleled view of the surrounding ocean framed by 20-foot floor-to-ceiling windows.
