Fleet races can have anywhere from four boats to hundreds of boats in a race. A regatta must have at least three races to be counted. Each boat's place in each race is added to compile a final score. The lowest scorer wins.
In match racing only two boats compete against each other. The best known competition of this type is the America's Cup. The tactics involved in match racing are different from those of other races, because the objective is merely to arrive at the finish line before the opponent, which is not necessarily as fast as possible. The tactics involved at the start are also special.
Team racing is most often between two teams of three boats each. It involves similar technique to match racing but has the added dimension that it is the overall scoring of the race that matters. In three on three team racing, this means that the team that scores ten or less points wins.
