Hi Wouter,
I have some ideas regarding the F16 rules.I think you should look at restricting materials for beams and masts to aluminium. This would hopefully keep costs under control and as the minimum weight already allows boats using these materials to come in at minimum weight it shouldn't affect the performance of the class to much. What worries me is in the future somebody with a huge bank balance might get carbon parts custom made such as a mast with a very light tip and very heavy lower section allowing it to pass the weight rule for masts, as the rule measures the overall weight. This could give him a very small advantage and if he was a good enough sailor winning races, others may think the mast is the reason why and feel the only way to keep up is to spend the same sort of money.
Something else I am interested to know regarding the F16 rules if I put a larger rig and wings on my Mosquito and it all fitted within the F16 rule would I be able to race as a optimised F16. I have sold Twice Bitten and am currently looking at getting a new boat made out of the same mould as Tim's boat, I sailed Tim's at a recent reggatta and it was faster than Twice Bitten and more bouyant, possibly able to cope with full F16 weight, so think it may be worth having two rigs and take on the Taipans and others with F16 rig.

Regards Gary.
