Jay Chau, vice chairman of the Hong Kong Kiteboarding Federation, takes part in a training session at Shui Hau Wan at Hong Kong's Lantau Island May 12, 2012. The International Sailing Federation (ISAF) announced the decision to include men's and women's kiteboarding at the expense of windsurfing earlier this month, describing it as a "fantastic addition" for the Games in Rio de Janeiro.
