Eric is spot on here.

As to the disciplines and differences, the rules are remarkably similar for most aspects of fleet, team and match racing. And, this works well. The rules are interpreted, and plays are developed, based on these rules, for team and match racing.

Some of these plays work equally well in fleet racing, but for the most part, you lose the fleet when you tangle with a single boat, so most sailors neither learn/understand the rules, nor race this way. About the only time match racing tactics work in fleet racing is during the last race or few races of a series when two boats are very close in points, but not in danger of losing to others (typically two boats fighting for the overall win at a week-long nationals, for example).
