Wouter,
For me it is logical to have a boat that is a little (maximum 5kg) superior from the limit. You can place the weight where you would like... Having to had some weight to be at the class regulation is not a the way it should be done (in my point of view).
Now a minimum weight should not be the only objective and I think you agree with that. Personnaly, I believe that 180kg is much too heavy for a Racing Boat. It was in the past more a problem of technology than it would be today. Now I do understand that we need to set rules to have a class and accept it, I just feel that 180kg in low wind situation is much to heavy.
I'm not saying that "Z Class is better than Y Class", or "Z is the Best"... not at all. On paper the class is very open, inovative and this is great for our sport.
Possibly the current Manufacturer has done mistakes (who did not), so let's give them constructive input to improve a class that is "interesting" on the paper...
This is what I'm trying to do with MattiaSport that accepted to build two prototype of 18HT (on my request), and future will tell us if our prototypes are good enough to be launched as a serie or not. Nevertheless we do not pretend to have invented the wheel, but we are working with existing products and try to make them work together.
Sure we will have plenty of opprotunities to talk about this later on.
