Dufour vs Dehler
Both make fine boats with the edge definitely going to Dehler in overall quality. I''d put Dufour a cut above the Big Three (Hunter, Beneteau, Catalina) in quality and then Dehler a cut above Dufour. Dehler has stressed performance in prior models much more than Dufour. Having said that, I know Dufour is pushing performance in this new line.
I''ve spent considerable time poking through Dehler 36 and 39, and Dufour Classic 36 and 38. Dehler designs are narrower beam (thus less volume below) with deck layouts more attuned to racing. Dufour Classics are aimed more at cruising. I think a choice between the two would depend on your primary use -- cruising or racing. Certainly folks in Europe race Dufours and reportedly do well according to their posts on Sailnet. (Do racers ever say "my boat is a tub and I always come in last?") My first choice would be a Dehler of the two, but also want to see this new line from Dufour.
