Replacing Hatch Plexiglas

[Jimbo2010]

I see all the micro cracks from UV breaking down the materiel, in the mid and foredeck hatches.

What is the best materiel to use to make a longer lasting replacement?

If your hatches have gone 20 years or so in lots of direct sunlight you have found the best material.

CAST acrylic. Don't use extruded acrylic. Lexan (polycarbonate) is stronger, but 1 year in the sun will bring it down to cast acrylic strength, and it goes down from there. It is likely that your current hatches are cast acrylic. We have a regular here who rebuilds hatches - who should chime in.
