I am not understanding why someone would put a 4" hole in a deck. Dorads okay, if you can plug in heavy weather. The problem I see is if you go upside down that's alot of water that can get in. I won't even mention core problems if not installed correctly. All this for a little air that a porthole provides when needed. I would glass it and fair it then gelcoat it. Just me.
