PAY $500,000 TO LIVE ON OKTO CUSTOM-BUILT MOTOR YACTH FOR ONE WEEK - PICTURES

OKTO is a beautiful beast, a 66-meter custom-built motor yacht launched by Italy's ISA yard in 2014.

With gray and black decking and sleek interiors, she looks like the plaything of a billionaire movie villain.

For half a million dollars a week, you'll get your own helicopter landing pad, an elevator, Jacuzzi, pool, gym, seven-meter speedboat and plenty of towables and toys.

 Five suites accommodate up to 10 guests served by a crew of 17.

If you're the one forking out for her you'll probably want to bag the VIP Stateroom.

As far as destinations are concerned, you can pick from hundreds of idyllic Caribbean islands and hideaways in winter, or the Mediterranean in summer.
