The hinges on my Bomar hatch (the cockpit hatch under the lazarette leading underneath into the back berth area) are broken. Need to replace it. Anyone know how to remove the hatch ring? Removed the 14 screws but the ring won't come out. Any advice?

From what you've described I'd have to assume you're up against the original sealant or bedding compound. Try working a sharp edged putty Knife around the perimeter prying upward as you go. If it was bedded properly it should come up with some effort and patience. If still stubborn, heat the surfaces up with a hairdryer or heat gun held at a distance (objective being warm as much as possible without deforming the hatch ring). Start at a corner with the knife and gentle upward prying force as you go, work around the perimeter. Old sun bleached plastic won't stand for to much persuasion, iterative passes are better more force. Good luck.

Following. Gonna have to do the same thing myself over winter to fix a leak. Go figure. Its the one hatch on my H36 that's under canvas, and under a seat, and it still leaks. I ended up buying a new trim ring from SBO as the ring that's in now is already cracked in a few places where the screws are driven through it. Planning on using butyl to seat the new trim ring.

Thanks a lot, Curtis. Al confirms. May have to meticulously chip it out. Reconsidering leaving it for now with a semi-functional hatch.

Sent a private message. Former dealer and involved with the water ballast. Knew Al you spoke about from the time he started with Hunter. They probably used 5200 To the other poster, you may have a slight depression on that edge where the frame sits and used a plastic shim to level out the edge. Also never over tighten screws as it can cause plastic to crack.
Can you take a photo of the inside port hole?
Former dealer very much involved with the water ballast now retired

Little wedges around the hatch will help. I found many uses for these at home and on the boat.
