I don't know where the market for these yachts comes from... with fuel prices and all, even the guys that buy them must keep them for a while...
People buying boats now are older... and getting older. Something needs to be done to make boating more attractive (and affordable) to young people beyond the PWC stage.
In the 50's many built their own boats from skiffs to cruisers. I don't know the answer but, the industry needs to figure this one out.
