The Necker Nymph, which resides on Branson’s luxury catamaran, the Necker Belle, is an open-cabin three-seater sub. It dives down to a depth of 30m, a top underwater speed of six knots, and can remain submerged for up to two hours.
Both passengers wear normal scuba breathing gear — no, you don’t get to drive this one-of-a-kind winged submarine, there’s a pilot for that. A day-long rental will set you back $US2500 and unfortunately does not include Barbara Bach. [Necker Belle via Gadget Review]
