Great Lakes Multihull Racing Association

GLMRA's purpose is provide offshore multihull sailors with a rating rule and certificate, universally accepted throughout the region such that on any day a well prepared boat and skilled crew, fairly sailed and respectful of GLMRA, USSAILING and ISF rules, regulations and procedures, may equally have the opportunity to win in competition. This class is intended to encourage innovation and participation in racing on the Great Lakes, minimize confusion and partisanship, allow for the expedient development of boats and equipment, encourage innovation and safety as well as respect balanced interests of fair competition and sportsmanship.
