I don't know if it has been mentioned but the boat brand that started this thread off way back, Sirus, has moved ahead with their new 40DS. Here is a 3D of it.
These are really cool pilot houses for northern latitudes and they put tons of thought into the design with lots of owner feedback. The site is full of images where they are test fitting the interior with mockups.
And here is the first hull.
Very beautiful boats and definitely interesting. Hope this wasn't a dupe but was checking out their site and couldn't help but be interested in the updates.
