Paulo, I don't think Mr.Perry is patronizing us, neither that his language is rude and insulting (the exception being the qualification "stupid" regarding Eric's opinion at the end of post 6029 just before the text in mandarin). It is obvious that Mr.Perry has strong yopinions on the issue of chines (like you do) and he expresses them in a more straightforward and less explanatory manner. I believe that your last sentence of your quoted post "For that type of rude talk, bitter discussion and insulting language you have other threads, not this one" will not benefit this thread if Mr. Perry decides not to post anymore here. I will miss him and I believe I will not be the only one. He is a well known designer and I do not accept the depreciating view that this qualification is relevant only to the history of yacht design.
I don't have strong opinions about chines. I am interesting in facts and in why the best world's designers are using them in racing boats and cruising boats and also why on pure racing regatta top crewed boats there seems to be mixed opinions about its effectiveness.
I guess that call my view about chines as myopic is close to stupid and if not insulting his ways are rude and express the opinion of someone that thinks that knows more about it not only than me but more than all other top Nas that use them in cruising boats.
Regarding this : "I do not accept the depreciating view that this qualification is relevant only to the history of yacht"
, I certainly had not said that. I said that personally I have no particular interest in his recent work, that contrary to older one is not pushing the boundaries of sailing development.
His opinion and his views on the subject regarding the use of modern chines in cruising boast (fashionable as he sees them) have the relevance of coming from a NA but they are not more relevant than the ones from all the top contemporary Nas that design them on their cruising boats.
It is not about Mr Perry opinion, but about the way he expresses it and the way he wants to convince all that his opinion is more relevant than other's opinions, namely regarding all those top Na that use them on their cruising boats and also with the rudeness he expresses it.
