Glass windows?

[Epicurean]

I need to replace curved windows on my aluminium catamaran. The acrylic is 11 years old and it has a lot of microcrazing that makes them pretty opaque. It also has some other scratches and distortions. I'm thinking of going to glass and am interested in experiences others may have had with it, in outcomes, and having it fabricated. I am aware that glass can shatter, as can acrylic under different conditions. Also, glass is heavier and has different thermal expansion properties. I also don't think polycarbonate is what I'm looking for. I'm tired of boats with windows with poor optical properties. Then, too, there are different types of glass; tempered, toughened and laminated.
Of course, a big question is who can do it?
