I think you are not realising the full extent of his work of art. The hatch is built that way on purpose, it's like a screensaver or "calming" elevator music, so he can see the dolphins (or sharks) swimming along with him underwater, it's for meditation.
I still (want?) think he's going to make it.
I have no problem with the location of the hatch - in fact I'm happy to see that he has one so located for emergencies, and yes, watching the sea life go by would be great. I question the actual hatch that he used. And it may be a simple case of misjudging the true waterline of the boat, but that should set an alarm or two off as well (increased weight = increased loading, etc.).
I would love to see a simple and unconventional effort prove successful, and I think there may be a thing or two to what he's trying. But after seeing the pic of the join area of the main beams and close ups of some of the construction details, I have very little hope of a good outcome.
