OK, curiosity is getting the best of me. Why do you need a waterproof hatch?

You are most likely going to have to fabricate something based on the dimensions you have to work with. Build it out of exterior grade plywood, glass it over, gelcoat it, install.

With all of the makes and models of boats out there, I would be surprised if you found something that fit perfectly. If you build it yourself properly, you can make it the way you want it and it would last the life of the boat.

One thing to consider while doing this is water drainage. Make sure the water that is on the deck has a way to drain off the deck or into the bilge and get pumped out.

I recently built mine out of exterior ply , sealed with the old timers formula I found in this forum .

Sealed it well , I will dig up some pics

I had a problem like this on an old Wellcraft i had. Water would drip in on motor where the cover fit to the inner transom. I cut a piece of 4" PVC cut in half length wise , bolted it to the inner transom to make sort of gutter to run the water off the engine. .Worked pretty good. Just a thought.

to have a water-tight seal is to have powered hatches with either pneumatic seals, or compressive seals and a knife-edge

to have a weather-tight seal is to have a coaming with a cutter, and a return edge on the hatch that drops into the gutter

I would correctly build the hatch to drain into the coaming gutter
