55th Annual NAMBA Nationals

Join top racers from across the country as they compete for the North American Model Boating Association (NAMBA) 2026 National Championships in a week-long celebration of speed, skill, and competition. This milestone event is held in conjunction with the H1 Unlimited Hydroplane Races, part of the legendary Tri-City Water Follies Columbia Cup! For the Nationals event, races are organized based on engine sizes, fuel types, and by various hull types (i.e. hydroplane, mono, tunnel hull, etc.). Each class is then broken down into four heats of racing in which each racer is awarded points based on their finish. The racer with the most points scored after four heats of racing is declared the winner. NAMBA is a non-profit association of radio controlled model boat enthusiasts of all ages, genders and backgrounds from all over the world.
