For the past year we've done lots of armchair
research on
Jeanneau,
Beneteau, and
Dufour in the 37-45' range, roughly 1988-2005 vintage. Also threw in some
Bavaria as well.
It shouldn't shock anyone, but it is no absolute to claim one better than the other. Within any manufacturer, different models have different "issues" and even a model can vary by year. Some examples:
The
Jeanneau 40 lowers are backed by washers, not plates. Really! Found this on the
internet, and apparently Jeanneau makes a proper replacement, but it's not drop in.
The Jeanneau 42 series 1 has a traditional
rib structure, while the series 3 has a Beneteau-style bonded shell. I won't argue which is better, just that this model of
boat has a significant change in architecture.
The
Dufour has the Gibsea line, which is a reduced-cost (and quality) line.
There was an issue with improper
cooling in the Beneteau 400 and this model ate motors. The problem was identified long ago, but I wonder how many B400s have motors that are near death.
We are looking for a B430, and looked at a rather beat example. Then we looked at a Beneteau 411, and wife was ecstatic with it's beauty- it had been well maintained. No, no, no I said- look at how cheesy the
wood is, look at how thin the glas is, look at the unfinished sides on the floorboards. The two
boats may both be Beneteau but they share almost no commonality.
One of my common comparisons of models that have a high probability to be purchased is the Jeanneau 12.5, Dufour 41, and Beneteau 411. Of those the Beneteau is my least favorite, more for ergonomics and aesthetics. But I do believe the Beneteau to be of less build quality. That said, there are lots of 411s and not many Dufour 41, so there is a higher probability of finding a quality B411 at a good
price.
So I don't think one can say that one manufacturer is better. Pick a
boat and age, and compare it to the competition.
