If you're going to through-bolt the ports, I recommend that you chamfer/countersink the holes on both sides slightly, since that will help prevent stress cracks from forming at the holes.

A very different but also very harsh environment.
It is necessary AFAIK to drill the screw or bolt holes oversized and install grommets in the holes to insulate the plastic from any shock or concentrated pressure from the fasteners. I've used screws and bolts with shoulders to install plastic windows to prevent over tightening cracks in the plastic.

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.
