Read the full article (http://www.ocean2air.co.za) - these new boards have been designed and developd in South Africa in Durban by Rob Chrystal and Greg De Beyer. The board uses new technology and material to produce a faster and more dynamic board.
The Mavric concept redirects the waterflow under the board so that the spray is reduced and is pushed downwards giving the board dynamic lift thus reducing drag. The dipped rail allows the board to be ridden flatter causing the board to plane whilst still maintaining enough lateral resistance to sail high into the wind.
