Lake Havasu Events


Each two-person team boat team and three-person stand-up PWC team kicks off their racing with the Le Mans start. This means that all racers start off on the sand and race to their awaiting boat or PWC in the water as soon as the flag drops.

Spectators can watch for free from the shoreline. If you go out on the water on race day, be aware of the designated racecourse. Stay well away from the markers to avoid possible collision with the racers. The start/finish line is at Crazy Horse. Prizes will be awarded at a special banquet after the day's racing concludes. But this is only open to the participants.
