The hinges have broken on Mondial's forward hatch and so I need to change it out. This one is a replacement from several years ago. I thought at the time that it was a "Gray Marine" sold by Bomar. What have others done about replacing their hatches? Of course, I'd prefer not to have to grind out the deck opening to fit a larger hatch. I believe the Gray Marine hatch used a deck opening of 19.5" by 19.5".
