Ictus - fin powered speedboat

diewa: Ictus - fin powered speedboat

Fin-powered vessels have been developed throughout the last century, but never reached satisfactory efficiency with artificial fins. The newly patented Fin-Ray-Effect uses pressure distribution, similar to actual fish fins, enables this fin-powered speedboat to turn 86 % of spent energy into thrust, rather than the 70 % common with most propellers. Its four fins guarantee a very powerful but silent, wave-reducing speedboat ride. This model was introduced at the Hannover Industry Fair April 2004, department `BIONIC.
