Charter Richard Branson's yacht

The British billionaire and Virgin Group chairman is renting out his ultra-luxe sea retreat -- for $88,000 per week.

Owners -- even billionaires -- often charter their yachts to offset running costs and to keep their yachts in peak condition, according to Clemmie Proctor of Burgess brokerage firm.

Branson purchased the yacht in 2006 for Virgin Limited Edition's collection of retreats, which includes Necker Island in the British Virgin Islands. Branson spends time at all his luxury havens but also rents them out as part of his business venture.
