And at the same time tihey have to be quick to build, light, durable, resistant, reliable, esthetically pleasing and ... cheap. From a design point of view this looks way more complicated than conceiving the rest of a boat. 

I consider the window technology and the conditioning of internal space of cars at the top of what technology compromises can offer in that regard, profiting from the enourmous economy of scale. There are important lessons to be learned. Plus for boats we need to add further constraints like stronger forces and even more water proof.
