I like much of what Dufour has been doing, but even among the recent crop of plumb stemmed boats I find these boats particularly 'boxy' in profile.. not exactly pretty.. I think the sheer must be more parallel to the DWL than most others....
Like in the D36P, I like everything I SEE in the new D410, but it needs to shed weight. Thanks for posting!.
I like the overall design (graphically speaking) even if I prefer boats less beamier. But I understand the concept in what regards to having a more stable platform and a boat that heels less for the average cruiser that wants his boat mostly to sail downwind and will not sail with a head on wind. After all the vast majority of cruisers motor on those conditions, so yes, this boat makes sense. The boat was bettered in that respect in what regards the previous model, the 405. This one is considerably more beamy (4.20 to 3.98m) and has all beam brought back.
This is, as the last Dufour a Felci design so I have no doubt that it is an efficient and well designed boat for what it is intended to do but I fail to understand why the previous boat weighted 8 990kg and this one 9 430kg. Weight certainly is not an advantage and serves no purpose. Maybe the bigger volume of this boat? Anyway I don't like that extra weight.
Like on the previous model I don't like the B/D ratio of this boat, that is on the low side: 27.5%. I know that it is a bit better than the one of the 405 and this boat has more draft (2.10 for 2.03). This two factors and a substantially bigger beam will give it a bigger RM compared with the previous model, but than it is needed because the boat will have more wave drag and more wet area (more heavier).
I did not saw the keel design but I don't believe that it will be less modern than on the previous model and then we are talking about a torpedo keel with all the ballast down. That will give to this boat a sufficient AVS, but I like boats with a bigger part of its stability coming from the ballast. This boat will sail well, I am sure, in almost all conditions, except close against the wind in a blow were the power needed to overcome the waves and the added wave drag will not be probably enough for a good speed. The boat will heel and the ballast will not be able to give him that extra pull to cope well with those conditions.
Other mass productions boats will do better on those conditions.
Regarding the sail area I don't understand also why the previous boat that was 560kg lighter and had less have drag had more sail upwind (81.90m2 to 71.0m2). That is a big difference and hardly understandable since this boat has more RM and can therefore carry more sail.
A jeanneau 409, that has a better B/D ratio (30%), less beam (3.99m) and weights 1980kg less has more 7m2 of sail and I am not talking about the performance version but about the standard one.
I guess the infusion process is responsible for that big weight difference, but I really don't see how the Dufour 410 can compete with the jeanneau 409, that seems just a better sailing boat. I have also looked recently to other boats on this class and remember that the Hanse 415 has a performance almost as good as the one from the Jeanneau.
The Hanse 415 is, in what regards the hull more similar to the Dufour, both boats have a similar beam and the Hanse is even heavier, weighting more 530kg but it has a much better B/D ratio (32.5%), having a bigger RM and carries more 16m2 of sail and that is a lot.
So I guess I don't like very much the Dufour in what likes its general sailing picture.
Regarding the interior it is a bit risky to talk only about designs but I would say that it seems nice, following the general tendency of a polivalent chart table but I don't like the galley. I mean, it seems big enough but will not offer any support for the back, so I guess that on that one if on the sea you will have to tack the boat to the right side, or maybe the boat heels so little than that it would not be necessary, especially because the boat really only heels hard when pressed against the wind and again, the ones that are going to do buy this boat will not do that (or they have chosen the wrong boat) and therefore all is well
