Branson’s Underwater Explorer

alg_necker_nymph_virginEntrepreneur, adventurer and island owner Richard Branson is seemingly always pushing the limits of innovation and technology. One of Bransons new projects is aimed making is already exclusive private island in the BVI even more luxurious. 

Branson’s Virgin Group will be offering rides in the winged submarine called the Necker Nymph at his exclusive private island Necker Island. For now rides are limited to relatively shallow depths with the vehicle offers open views as you ‘fly’ through the ocean.

Wings on the carbon fiber submarine operate in much the same way as wings on an airplane allowing it to dive, turn and rise again to the surface. The 15 foot submarine is built by Hawkes Ocean Technologies and cost $660,000 to build.

A week of crusising in Bransons submarine costs $113,000 which inlcudes a week long stay at Necker Island. Ever pushing the envelope a deep sea sub is in the works capable of diving down to 35,000 feet beneath the surface.
