Virgin recently unveiled the latest addition to Richard Branson’s luxury fleets, the Necker Nymph,  an underwater plane that will fly riders into the depths of the Caribbean Sea. Beginning on Feb. 20, two riders and a pilot will be able to dive underwater for $25,000 a week. But that’s only after spending around $300,000 for a one-week stay on Necker Island,  Virgin Group Chairman Richard Branson’s own private island. The underwater plane uses downward pressure on its wings to effectively fly through the water for periods of up to two hours at a time, with the passengers getting a full 360-degree view out of the plane’s open cockpit.

The Necker Nymph’s typical speed is 2 to 5 nautical miles per hour and it can dive more than 100 feet, according to Karen Hawkes, a spokeswoman for Hawkes Ocean Technologies, the company that designed the Nymph. A statement released Friday by Virgin Limited Edition, described the Nymph’s launch like a plane’s takeoff. “Gliding on the water’s surface like an aeroplane on a runway, one of the three pilots will operate the joystick to smoothly dive down.”

It can be launched from a 105-foot yacht attached to the island — the Necker Belle — or from the shore. Necker Belle is rented out to guests for $88,000 a week, bringing the full Necker Island experience to more than $400,000 per week. What do you think?
