When you start talking about curved boards and foiling then you get the possibility of some serious expense. Most of the other items that are being proposed are self governing. For example, the head size on the sails. If you have a pin head sail and move to a square top it has proven faster over most conditions. The A class has no restrictions on mast height, head size etc. They experimented with heads that got huge and found there was a definite limit. For a very short time you found a few teams running many different configurations. Go to an A class event now and all the masts are virtually the same height and the heads on the sails fall into a very narrow range of widths. There is an attraction to some to be able to change small things and we all learn as a result.

As far as your sails go Aido, who told you they were illegal? There are only a few restrictions on what you can do and these have not changed since the first version of the rules in 04 as far as I know and definitely, in 10 when the Isaf version was written there are no changes that can be made to rules for a period of 5 years. There never have been any material restrictions in the F16 class.

I heard rumor that this was the reason the Chairman resigned the class, because of things being done without approval
