Keep in mind you can get hatches in a surface mount or a flange lip configuration (the latter has a lip that slides into the deck opening) Perhaps you should be looking for a surface mount that is more forgiving for slight offset in hole size. The lipped hatches provide a more finished look inside with less work.
C&C may have produced their own hatches but my recollection is that they used Bomar, at least for a time.

I don't see any link in your post. Sounds like a good one if you could repost!

If C&C built it, these are the folks that provided it. They have an active rebuild program and to save yourself a lot of grief I would talk to them first. (no matter what you decide to do).

There are two issues size as you have found and corner radius which you may have overlooked tends to be bigger on new hatchs
So even if you find one for a 19 x 19 hole you have to check the radius as it may not fill the hole
I found it better to rebuild and not have to cut a new hole and drill new holes and if the hatch is on a raised section of the deck to make a flat area thats a real can of worms

Hatch Replacement on C&C 25 mkII
I am looking to fix my leaky deck hatch on my 1983 C&C 25 mk II. I have decided that I would prefer to replace the whole thing with a modern Lewmar or Bomar hatch since the existing hatch is generally kind of crappy looking. My problem lies in the fact that from what I can measure the outer dimensions of the hatch are 20 1/4'' x 20 1/4" and the cut-out is approximately 19"x19" and I can't find a manufacturer that has an appropriately sized replacement hatch. Has anybody else replaced a hatch on this era of C&C? Are there any good methods of getting a modern hatch into the existing hole? What kind of options are available to me if not? I've only had the boat a year and this is the first major project that I am undertaking so forgive me if I'm not all that savvy in the field of boat repair (though I'd like to be). Thanks in advance for any suggestions!
