FYI for anyone with a Lexan or Plexiglass hatch that is cracked or broken you can repair the material with IPS Weld On number 40 a commercial grade epoxy. We repaired a load bearing 3/4 inch piece of Lexan with this successfully cost about $40 compared to having a hatch fabricated for $300
Note weld on 3 or 16 will not work for a major repair only 40 and that is commercial not retail so searching was required

On an old boat you need to "do-it-yourself" which means disassembling the broken hatch to remove the plastic and then Goggling "plastics acrylics" and getting a replacement piece of plexiglass. Then put the hatch back together.
- - It would greatly help if you posted photos of the "broken hatch" so folks could offer suggestions on how to repair it.
