The flange of the hatch will hide
the cut edge surely?

Cutting Fibreglass

I use carbide coated jigsaw blades; Piranha by Black and Decker, packaging has a number X26061-XJ. Meant for cutting ceramics and fibreglass. Never had any problems with the gelcoat chipping or cracking

We tend to cut the corners with a hole saw and join them by cutting the straight lines with a fine cutting blade in a grinderette. It's neat.

Put insulation tape over where you've got to cut.Mark the tape up after taping and cut using Moller's method.

You're guaranteed it won't chip.

1 use an angle grinder with a thin cutting disc, you do have to be confident though!
