Scientific American reported not long ago on "an amazing and little-reported technology that allows naval weapons and vessels to travel submerged at hundreds of miles per hour – in some cases, faster than the speed of sound in water. The swiftest traditional undersea technologies, in contrast, are limited to a maximum of about 80 mph."

The new technology that allows for these incredible speeds is "is based on the physical phenomenon of supercavitation."

A new goal for boatdesign.net?
