Multiman - my point was only an example of the rules I suggested would have covered the entire size issue. For both the Mini40 and F-48 Classes, the rules specify maximum dimensions - and it was my point to show a smaller size (or boat) still met the rules.

To clarify "my" reasons for a narrower than allowed beam is the hope that tacking will happen faster and all three bows will cross the eye of the wind faster by being closer together than if they were further apart. My focus direction is for a fast tacking boat and I will give up a wider beam to achieve that. If I find it wasn't helpful, I can always widen the beam out to it's allowed 48 inch maximum (1.2 meter) size. Hopefully that will also address Andrew's post of the difference in maximum beam compared to a less-wide beam?

Regards - and keep the ideas and suggestions coming.
