No fleet is perfect. A few misjudgments and, therefore, rule infractions are bound to occur. New sailors often don't know the rules well. However, if a bad case of "bumper-car syndrome" develops in a fleet, it can really hurt participation. You don't want fleet members selling their boats because they've experienced too much aggression or damage, and you sure don't want to hear someone comment about your fleet, "Don't join that fleet-no one sails by the rules."
