Thats interesting to know... Moonen dont really divulge much information on their yachts "under construction".
I think you are right though, the huge interior volumes demanded are a lot more acceptable within the design of the Explorer type vessels. I have always liked explorer designs.
There is still something incredible about these, more "classical" designs. I think i just like the way of thinking at Moonen, and therefore the yachts they build (and architects/designers they use). Mind you, am have always struggled to warm to the Bradford Offshore 90' and 92' yachts.. but then again, maybe that's just me
