Yachts have long been a symbol of the rich and the famous, with marinas around the world full of their gleaming multimillion-pound toys.
But more and more people are now sampling this pampered lifestyle at sea on small boats and cruise ships styling themselves as superyachts.
At one end of the scale, you have operators in places like Croatia offering a week onboard a 38-passenger motor yacht for as little as £800pp. For that, you get a sundeck, hot tub, loungers and personal service that make you feel like a VIP.
At the other, there are high-end brands like Ritz-Carlton, Emerald and SeaDream, with their opulent restaurants, bars and suites.
