 The Ranger 37 was designed to the IOR handicap rule and was the last production boat to win the Southern Ocean Racing Conference (SORC is a winter ocean race out of Miami, Florida).The Ranger 32 is still competitive under PHRF handicap.While the Ranger 29 was designed to rate well under a number of handicap rules including the CCA and IOR, the boat does not fare so well under Portsmouth or PHRF.
