Just to say I understand what you are saying :

Point 5 adn 6 are of course a little over the top. I know that. The base of these points is that I personally, more enjoy being part of a modern class that allows modest development and freedom to tinker about than strickt OD classes.

The other points come down to any ones personal definition of SMOD, OD , formula and Open class. In the main body of my point I tried to use the definition that I think most sailor give to these markers. My own prefered (and different) definitions are :

SMOD : Single manufacturer One desig class - You may only use factory supplied/sold part and nothing else, you may not modify anything to the boat beyond the setup as it came from the factory

OD : One design. Strict specs are give on a number of important parts (hulls, mast etc) forcing very strong similarity while the parts themselfs may be made by any supplier or builders. A good part of the setup is left unspecified and can be modified and changed to sailors wished (sheet system etc). This rather closely resembles are very strickt formula setup.

Formula : A defined box rule forces several important specs to a size that strongly limits realistic performance. All within this box rule goes.

Open Class : Completely free in designing, building and modifying a catamaran. Racing is either first in wins or handicapped.
