With regard to whats in and whats out, I assume that the constitution was not handed down from above and is a document like and set of rules, written on paper and not carved in stone.
Everything evolves and it is only the speed at which this happens which is controlled. I am not say what if anything should change but the conditions should always be reviewed regularly and adjusted if required. What worked well 10 years ago may now need some tweaking.
I think there is always some confusion as to what the terms One Design mean. Jack Holt said that a one design ceased to be a one design the day you built the second boat. A one design does not mean and to be honest never has that each boat is identical in every aspect. Every boat fits within a set or rules however tight or loose and they are transparent and everyone can see what is or is not happening and can check it themselves.
I agree that there has been very poor leadership from the upper echelons of the sports management over the years - and it continues still! - which has allowed some more extreme versions to become the norm when perhaps they should have been stopped. However, every builder and sailor wants the edge even if they will not publicly admit it and so these situations are inevitable. Because of the development of new materials, speed differentials will always take place even without shape change and what ever you do, new boats are generally faster than older ones. Sailing is an equipment based sport and understanding and developing the equipment is a fundamental part of it.
The main factor with all the OD classes is the transparency. Whether you like it or not, the rules are there for everyone and sailors can get involved in decision making within the class. The rose coloured spectacles presented by SMOD's are just that. We are not talking about "a few kilo differences" but fundamental changes which you will never know about because you are not allowed to see the rules, specifications or any other document and you will certainly never be allowed to become part of the decision making process.
Maybe this has wondered a little off thread, but surely the benefit of using handicaps is that we can be inclusive and control any unwelcome "bandit" that way rather than deny membership in the first place.
