I'd have a hard time pinning down orn defining "American Style" but I think I know it when I see it. The same for "Euro style". Granted it's a broad generalization and many European boats don;t fit into that box but once again, I think I know it when I see it. Maybe I should have said "one of the Euro styles".
This is what I thimnk of as an American style boat:
I understand what you mean but that is as representative of American yacht design as Dijkstra classical designs are representative of European yacht design. In fact they are not, they are classical/modern Dutch designs.
The boat you have posted is not modern in a sense that it is not designed strictly with form/function in mind and beauty is searched not only by the fulfillment of a program but through a composition were a vernacular "language" is essential, even in prejudice of performance.
In that sense we can say that there is an American style an then you are right and your boat is a very nice example as are S&S late designs, including the ones for Morris yachts. But regarding that type of boats we cannot talk about European classic/traditional yachts, but about British classics, Dutch classics, French classics and Italian classics. Their traditional boats don't share entirely the same vocabulary.
But as those sailboats are in America and Europe very marginal in what regards today's production and does not represent the edge in contemporary design I don't think we can make them representative of contemporary American or European yacht design and we cannot say they are the American design style, or the European one.
Regarding American yacht studios I would say that the two more representative in the world panorama today are Farr yacht design and Reichel&Pugh, followed by Morrelli&Melvin, Tripp design and Mills design. They design for Europeans and for Americans and that design that you liked and that someone said it was typically European was in fact made in America by a American studio, this one:
When a design is made following form/function and is modern in the true sense of the word (modern art) it makes no difference to be designed by an American or an European studio in what regards style: They are using the same top knowledge in what regards hydrodynamics and using the same information that comes from racing so the hulls (following the different tendencies in racing) are very similar as well as the superstructures that are designed to have minimum windage and in what regards cruising, to maximize interior light.
Some yachts designed by American studios or by American NA:
Now what really make me pissed and if I was American I was even more is why all this great American studios work more for Europeans than for american shiphyards?
What in my opinion makes production American boats worse than the Europeans has not to do with building and but with quality in design.
While European mass producers call the best NA in the world to make their designs (including american studios), the American ones design them in the house with 2th rate NA. One of the few exception I know is C&C that had called Mills for designing their new boat. There is also Summit yachts but any of them are very small shipyards specialized in fast cruiser-racers not really big mass production builders like Hunter or Catalina.
Bottom point after the the rant: Your beautiful 46ft is certainly representative of American classic yacht design but I would not say that is representative of contemporary American yacht design as a whole. So in a way you are right when you say "American style boat
" referring to your design.
