        ONE DESIGN RIG (ODR) CLASSES      23 May 2015
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.
