With gyms, swimming pools, hot tubs, party rooms, walls filled with artwork, guest rooms and even heliport, the world's most luxurious yachts are true mansions at sea and can cost breathtaking figures - which is no problem for the select group of well-heeled buyers. In Brazil, Madame Kate, which was commissioned by businessman Alexandre Grendene, costing 74 million euros (R $ 318 million), is 60 meters long, and was designed by the renowned architect Tim Heywood. The yacht has innovative attractions such as pearly paint and a system of LED lights that makes it even more imposing at night.
