Slashgear‘s Chris Davies says this is just the ticket for up-and-coming Bond villains:
It looks like a half-submerged X-Wing, or maybe a Star Trek Shuttle, but it’s actually Ghost, one American start-up’s vision for what an attack helicopter designed for the navy might look like. Mustering 4,000 HP from two engines on the end of powered legs, Ghost promises to whip across the ocean in a supercavitation bubble, avoiding radar and with a silky smooth ride for the crew inside.
What makes the boat special is how it improves on hydroplane technology, more commonly used in racing boats. Hydroplanes increase their top speed by skimming across the top of the water, rather than burying their hulls in it, reducing drag in the process.
However, that also makes them relatively unstable and prone to flipping — so, Ghost’s manufacturer Juliet Marine Systems turned to supercavitation, which creates a bubble of gas around each of the legs and cuts drag by a factor of 900. Air is pulled down through the struts, while the propellers are at the front of the 62 foot long tubes, effectively pulling the vessel along.
