Air supported vessel

There is a strange boat in the harbour.
When it was on shore for a couple of days it was easy to study it. The bottom is very much as a catamaran but  with a conventional bow. In the front there is a big fan blowing air under the hull at a rate of 15 m3/sec. I saw when they started it, the whole boat lifted 15 cm. The boat is powered by two Volvo Penta diesels each at 300 hp. The boat can achieve a speed of more than 30 knots and the power requirements is about half of a conventional boat. It is a norwegian invention and today some americans is testing the boat and will build two 80 feet boats.
