AmbrosiaIII offers a life of luxury on the ocean for Euro40 million

If you've got it, flaunt it. That's the first rule of the sea for the ultrarich, and with a made-to-order yacht like Benetti's 65m AmbrosiaIII, there's no need to hold back. Built in Viareggio, Italy, it has a cruising speed of 14.5 knots, a range of 7,000 nautical miles, and accommodation for 12 guests and 20 crew on six deck levels. It comes, of course, with the very latest in everything, from satellite navigation systems and silent generators to bow thrusters, watermakers and stabilisers. But what really attracts potential buyers is the sheer scale of luxury on board and some of those 'added extras' which can be hard to do without. For example, there's the helipad, the jet pool and five open-air dining areas.

Interiors feature cherry wood furniture, teak, ash and exotic marble, while mother-of-pearl, gold leaf and onyx add the final touch. Prices start at about Euro40million (HK$454.5million), but there's one potential problem. If you're interested in buying, you just might have to join the queue behind all those Russian billionaires.
