Greetings Frank, Didn't you say it's your birthday? I was able to work up a CAD model of a hatch viewport arrangement, that would be pretty hydrodynamic and not a entanglement hazard. I made the retaining ring to be inset in the viewport seat. Also I nickel plated your hatch for you while you were sleeping. Lets just call it cabin fever, and leave it at that. ;)' Here is my Frappr link, to seven model rendering pictures of your hatch with a conical viewport. http://www.frappr.com/?a=viewphoto&id=4001713&pid=9062924 Regards,
