One of the most innovative ideas in sailing was developed by World Sailing Management in 1995. The idea dates back to ancient Roman times when emperors used to flood an arena and organise sea-battles. This spectacle was attended by thousands of spectators and was viewed as one of the great events of all time.

Time passed and the venue moved to the big ocean. The open expanse of water meant that viewing was limited. But that was before the O'Neill Champions Trophy, The Battle of Amsterdam. From the start the event was a success. Invited to sail in a canal in the middle of Amsterdam, on a parcours of 150 x 30 meters, with artificial wind reaching 8 knots, Olympic and World Champions are always excited about participating in such a new and innovative event.

The Battle of Amsterdam is regarded as an event that requires skill and talent not practised by sailors during regular competitive events. Every year the press, competitors and spectators react positively to Henri van der Aat's initiative to promote the sport of sailing to the public. After four years the participants are eager to gain the title of "Best sailor in the World" and are still eager to participate in such a challenging event with prizes and prize money worth more than 15,000 US dollars.
