Azuree 40FC - 5100 kg. From my perspective plus 1000 kg could be justified, specially then FinnFlyer or Sly aprox. 3 times more expensive, full carbon or have "Cupboards, doors, tables, floorboards, bulkheads, walls are also Advanced Composite Constructions, i.e. sandwich GRP laminates with Divinycell core and covered by vacuum bagged thin Teak or Oak."
I have already said that more expensive boats can be lighter because they use better materials and a more careful building. The Azuree cruiser does not enter on that category (it is an inexpensive boat for a fast boat). Besides those lighter boats don't cost 3 times more than the fast cruiser. They are bigger boats and they are not made of carbon even if some, like the fast cruiser uses some carbon mixed with less exotic fibers and some have no carbon at all.
Plus I guess there are some mistakes, just checked and:
Dispacement 6.900 kg
Ballast 2.520 kg
Dispacement 6.800 kg
Ballast 2900 kg
That's a bit rude isn't it?
I have already explained that there are not a single weight of a boat and boats have several drafts with different ballasts and weights. Probably the differences come from that, or do you think I had not checked the weights?
On the Finn Flyer site you have as weight for the 42: 7000 kg and 6800kg that correspond to two different keels with two different drafts, one with 2700kg other with 2900kg. For having the hull weight I have taken from the lighter boat the weight of th lighter keel. It gives 4100kg, as previously posted, regarding the Sly 42 I have used this file:
It gives the values I have posted. Probably the other values that you can find on the site refers to the smaller keel and that's why the ballast and the weight are bigger.
At the end of the day you never know the truth

I have already said that:
"one of the problems with the weight of a boat is that technically speaking there are a lot of weights in a boat: There are light weight, minimum sailing condition weight, medium weight and Max load weight".
Obviously most of the weights on the left column are empty weights and the values on the right column can go from minimum sailing condition to any weight near medium load. You will have water and fuel on the tanks and you will have the weight of all extra options you have put in the boat. I don't find anything strange about it.
Regarding the weight of the boats, fast boats are light boats and there is a lot of light boats around. As you like to check it out you can check the weight of these hulls, most or all without exotic materials and you will find they are all light:
A40; Zou 40.2; Malango 9.99; Fox 10.20; Azimuth 40; Pacer 376; JPK 110; Loft 40; Pogo 10.50; Pogo 12.50.
You will find also that they are a bit more expensive than more heavy boats. For doing them light you have to do them better
And some are used to race and that means that they have to be stronger than the average cruising boat.
And by the way, if you put doors and a more conventional interior on a Pogo you will probably will not add 600kg to the boat and that would still make it 1000kg lighter than the Azuree fast cruiser and the Pogo uses no exotic materials on his boats. How can they do that? Well, they have 20 years of experience in building strong and light race boats and use that knowledge to build light and strong cruising boats.
Bottom point, I have nothing against the Azuree, a boat that I like, specially in the Fast cruising version but it seems to me that doubting that other brands, with more experience in building light boats, cannot build significantly lighter boats than the Azuree, makes no sense to me. They do and you have just to look to find them
