While this is true... the ocean rarely causes impacts of this variety. I'd also point out that UV is a greater danger and that NO hatch manufacturer uses LEXAN in their hatches. All of them use either tempered glass or acrylic. The real problem is that any strong impact that is less than capable of shattering an acrylic port will generally cause a lexan port to flex and foreshorten enough to break the seal. Ports leaking is generally a much more common problem on a boat than them breaking.
My 2 cents worth, as was demonstrated to me by a friend and former boat yard owner, regular plexiglass will shatter when impacted an lexan will not, and most glass companies will cut lexan to order.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
