Hi Conrad,
Just so you know: Most Olympic classes allow variations in sail cut to accomodate variations in sailor's weight. As we all know "people are not one design". It has been proven in many different classes for at least 50 years that allowing the sailors to tailor the sail cut to their weight results in tighter competition and is totally consistent with the intent of one design sailboat racing. Forcing all sailors to use the same sail cut and mast stiffness allows variations in sailor's weight to have a greater effect on race outcome and it also makes more money for the boat company. How to handle this question depends on your goal, more money for one company or better racing.
