It is true that the development boats get faster over time, but this is more due to design changes like squaretop mainsails. However this is not a practical way of looking at it. It is better tho regard the modern designs as stationary and regard the non-developping OD classes are becoming slower in comparison.
You can view it like this, but the devopment c lasses are getting faster. So you propose to change all the OD classes numbers instead of a few development classes. Sounds like you are creating work here.
The biggest requirement of an rating system is to rated the popular racing designs
Agreed.
1 % difference is already 40 second per hour difference. A significant gap in a F18 world championship racing when fighting for place 1 to 3 but not far any other placings.
I've been sailing in races where 40 seconds has been the top 20. I think I'd have the 1% extra speed thanks.
Well, if Dart wants to optimize their profit margins and source out their sailmaking to some vietnamese sewing company then that is just not a problem of the Rating systems. Bad quality should be an input into a rating system.
I never said that Dart should do this. Don't put words in my mouth.
The tornado was rather fixed in its rig before 2000. It was certainly not as open as the formula classes. I seem to remember that the width of the sails at different heights were ruled upon. Please everybody, research the matter before making wild claims.
I was talking about the 2001+ Tornado. Mainsail shapes are different. It's not a wild claim, why else are poeple spending money on flat tops, Round tops and various cuts between this. I agreed it is not as open as a formula class, but it's still a development class.
Take a look at this picture, are all these mainsails the same. I think not :
