“I think there was only a 2 day period during the entire 4 weeks where the forecast was not at least 90% accurate. On the majority of the days it was spot on!
Thanks for the superb support you provided; it certainly helped us get top sailing nation in the games.”

Mark Robinson, Head Singapore Sailing Federation
