I find it very suprising that this guy is still attempting this. There must be people close to him, advising him against it. Did he not consult with any experts prior to designing/building his "boat"? I readily admit that I am no expert in marine engineering (in fact, i know nothing), but even I can see that the hatch or that type that goes below the waterline is a serious problem. I am sure that given that GLARING issue, that there are many others just below the surface that are bound to show up once he gets this craft on the open water.
