So OD means more money needs to be spent on the brand new hulls sails and foils. Is this because the quality can be lower than non-smod classes?
You completely missed the point there. The OD idea is LESS cost because an OD class doesn't have to buy the latest greatest stuff every other regatta.
Interesting theory you have on quality as well. Generally in a production setting you get more consistant quality, not less. You learn how to make things right.
