By all means that is "much" inside the thread
I am not sure the problem is a quality problem, I mean regarding materials and workmanship. For that I would have to visit the boat. This seems to me a design problem. I am pretty sure that the one that have made the sketches for the Dehler interior was the same that made the sketches for the hanse 325. The interior sketches from the Hanse 325 and from the Dehler 41 were previously posted on this thread.
You can see that is the same "artist" doing both drawings. The drawings are not bad but the quality of the design that is behind is mediocre. I had that sensation when I saw the drawings and now I can confirm it with the reality. You can make a drawing look good but you need trained eyes to see if want is going to be built based on that design is going to look good
It seems to me that the problem here is a design problem and extensive to Hanse. I don't know your opinion but I would say that technically the quality of the design of their interiors is a lot worse than the ones from Dufour, Benetau or Jeanneau (I am not talking about the quality of materials, that is equivalent). It seems that Hanse decided to take part in the design of the Dehler interior and the results are what we would expect.
They should have put instead the guys that used to design the interiors of the last Dehler designing the Hanse's interiors
The design of the boat interior is so important that today many boat builders give the interior design to a specialized studio other than the one responsible for the design of the boat (they work together). Most French boats work this way and the difference in design quality more than compensates the extra costs. Design quality can even hide shortcomings in material quality and that's a lot cheaper to have a boat well designed than a boat built with prime materials and a bad design. If you build a boat with prime materials and workmanship over a nasty design...well, it is going to look bad anyway, no matter the cost
