hi codog, I get your point about the cleaning issue and you can be sure I would not want anyone to mess with the clarity of the design

. After all the crew has to work with the yacht and there are many practical points, that should be taken into account at an early design stage, so that the design doesn´t get spoiled in the end (that would of course be my motivation).
As for the large windows... the patio doors on the maindeck of "sunray" for instance should not be made from 5m high glass panels, but have a division and supporting structure on the inside.The big windows in the hull of the "gorgeous" concept on the other hand would indeed become a problem, unless they could be shut completely in stormy seas. Btw. Can you still see through 150mm thick laminated glass

? .. Even though the fact, that it is bullet proof might be a nice side effect... If the windows have to be smaller on the inside, they should be also on the outside, there are so many yachts out there with fake windows... I don`t think that adds to the beauty of the structure, what brings me back to "honest construction".
Since you seem to know a lot about the actual construction of a yacht, is there a rule of thumb for the thickness of the glass window in relation to its size?
