The most common response to the Hyper-Sub is that it looks like something from a James Bond movie. The decidedly strange hybrid craft is a high-speed long-range speedboat which can also turn into a submarine. The craft has a capacity for only five people but boasts speeds of 40 knots and has a range on the surface of 500 miles. Submerged, it can dive to 250 feet. Reportedly, the US Marines are very interested in the Hyper-Sub. No doubt, it would also make a fun toy for a mogul who dreams of pretending to be James Bond.
