A class was developed along with B,C and D as development classes where only lenght, width and sail area restrictions were given.... outside that you could do what you liked.

From the B class came the Tornado OD, and for many years B class continued as a development class seperate from the T.

From what I have been told, the Moth class decided to go in two different directions years ago an the class split into the OD Europe dinghy and the development Moth.

Maybe if the A class wishes to further restrict the class rules they should consider moving to a OD multi manufacture class or formula class and allow the A class to continue on as a development class.

I just think before the class outright bans the use of foils, maybe a technical committe should be set up as the Tornado class did, experiment and report it's findings back to the class.

If the A class did decide down the track to adopt foils it will loose some of it's members but would gain many more from other classes as the Tornado and Moth classes did.

Just my opinion.
