I need to buy a new deck hatch. The choice seems to be either a Lewmar 60 or
a Houdini super 50 foredeck hatch. They are both the same size (they're
both the same size) The Lewmar has Perspex (12mm I think) and the Houdini
6mm toughen glass. Houdini are a lot cheaper and I quite like the idea of
toughened glass, but is toughened glass likely to shatter into little
squares if it's walloped by a clew or similar object


Yes. Glass breaks, perspex scratches and goes foggy. That's the choice.
