Missed this article earlier (posted June 4) but the ISAF has decided the two sailing classes for the Nanjing 2014 Youth Olympic Games

http://www.sailing.org/news/38686.php

One person dinghy (Boys and Girls) - Byte CII (resembles a Laser with a more modern sail)
Windsurfing (Boys and Girls) - Techno 293

Windsurfing is one of the two classes two years before the adult Olympics where there is no windsurfing class.

Maybe you are saying, "but wait, the 2016 Olympics are too close to this event for the equipment selection to be relevant."

Lara Vadlau (AUT) took gold in the girls Byte CII in Singapore and followed this up with a gold at the 2011 ISAF Youth Worlds. The Austrian then qualified her country for the London 2012 Olympic Sailing Competition at the 2012 470 World Championships marking a fantastic run of results stemming from the inaugural Youth Olympic Games.
