If I see correctly, the base of the screen is screwed to the hull? At least there is now less than the advertised 12.7 cm of carbon fibre composite at that point.
I had a similar thought. When I saw the monitors, I thought "How are they mounted to the hull? They wouldn't screw them into it...." well, it turns out they did.
Which is a bad idea in any sense. But then, looking at the pictures, I wouldn't dive deeper than a bathtub in that thing, even if I was paid 250k to do so. It looks like a carbon fiber tube with some clued on cameras, lights, propulsion and balast. Which is far, far from being a properly designed and engineered sub. Or boat. Or piece of furniture...
