I dont think it was mentioned here, but we once saw a pre-2000 52' Krogen Express and the side cockpit access door had no hinge. not sure of the terminology but it had a sort of mitre slot arrangement where the door lifted straight up to remove it and it was unattached. when you wanted to close it you slid it downward into the slots on each side (sorry don't have a photo).
It was simple and required no metal hardware. My only concern is that when lifting, you might accidentally drop the door over the side into the water... yikes!
