ONE DESIGN RIG (ODR) CLASSES 14 July 2007
Those ODR boats that are raced in their one-design class rule rig and sail configuration should
be handicapped as though they meet the base handicap assumptions and should not be further
penalized for overlength spinnaker poles, etc., provided they essentially conform to the
dimensions given below.
For those models where you follow this recommended practice, please so indicate by entering the
abbreviation "ODR" after the model name.
