Once I had mastered the basics of windsurfing (got my level 2) , during late summer 2013, I was invited to join HOLWAC (Hollingworth Lake Water Activity Centre) . The club introduced me to the RYA T15 series for TECHNO 293 windsurfs. This enabled me to train alongside other windsurfers, using similar equipment and develop my racing skills in a really fun way. http://www.rya.org.uk
