No, it's not the latest floating lair for Bond's newest villain.
It belongs to Russian billionaire Andrey Melnichenko, who's currently worth around $9 billion and probably thinks that £260 million is quite cheap.
Lovingly named 'Sailing Yacht A', this behemoth is currently undergoing its first sea trials in Germany.
You want a rundown of why it's so expensive? Well, let's start with it having eight floors and being 300ft high. Then, there's an underwater observation deck, a helicopter pad, and the main mast is so big that is has a small room inside. Whoa indeed.
It'll accommodate 20 guests and a 54 man crew, with a top speed of 24mph.
This isn't even the Russian billionaire's first superyacht - his previous vessel was a £190m model.
It already looks amazing and it's not even in use yet. We'll take a free ride if there's any going, Andrey.
