In 2000, the Weymouth and Portland National Sailing Academy was built in Osprey Quay in Underhill as a centre for sailing in the United Kingdom. Weymouth and Portland's waters were credited by the Royal Yachting Association as the best in Northern Europe. Weymouth and Portland regularly host local, national and international sailing events in their waters; these include the J/24 World Championships in 2005, trials for the 2004 Athens Olympics, the ISAF World Championship 2006, the BUSA Fleet Racing Championships, and the RYA Youth National Championships.
