There are a couple of things about Raven that bother me, but in general I really admire the open plan and flexible space.
I'm not sure about the "moving floor". I built my house and my boat, I don't have the house any more but I can/could walk through either of them with my eyes closed and not miss a step. In Raven you might spend a lot of time wondering if that floor is there or not? And I really don't like loose floor boards in a boat that goes to sea. I'll guess she's fine most of the time inside here, but there could be a problem in short-sharp seas.
The too-low roof over the after deck bothered me for a while. But once you've seen the boat and noticed the dinghy storage is in that aft deck, it makes some sense.
