Which is probably is.
But then, I remember the data for the 20+ year old Dehler38 (no, not the new one):
LOA 38 ft (11,40 m)
Beam 3,78 m
Draft 2,05 m
Displacement 5500 kg
keel 49% (2800 kg)
Main 40.5 sqm
genua 1 41 sqm
There been some discussion in this thread what is to be considered "light", as "light" is something new, and very special. It is not. This old Dehler is not even minimalistic. (there are more examples from this period)
The Dehler 38 is a 1987 model and yes a very light one for its time. The VK 35 weights several hundreds of kilos less and can only be considered light for a 35ft aluminium boat. It is difficult to make small aluminium boats light. The weight in the aluminium building is not like in fiberglass proportional to size. You can make a 40ft or a 45ft aluminium boat proportionally lighter.
Talking about light boats in modern terms, like the Dehler 38 was light in its days, we would be talking about a JPK 38 (5000kgs) or about the Pogo 10.50 (3600kg) but as we saw here many times the announced weight is not the real sailboat weight but the weight the designer thought it was possible for that boat.
Considering that a modern Dehler 38 weights 7000kg that difference is hard to justify or understand since the new 38 Dehler is a faster boat.
