An umpire is a person who functions as a race official by applying the rules of the sport (match racing or team racing) to racing situations, primarily on the water, as situations occur to resolve rules issues.
To umpire match and team races is no easy task, but you will find that the satisfaction of contributing to the growth of our sport and serving competitors makes the work well worth the effort.
