That is strange. When was that hull built? I wonder if someone designed a jet hydro today, how would they do the bottom in relation to the intake. If I were you, I'd give Jeff Bennet a call to pick his brain about your hull, and see what ideas he might have. NASA did when they wanted to know what happened to the space shuttle when it blew up last Feb. They hired him, as well as other aerodynamic experts to figure out what happened. So, if NASA wants his knowledge, I think it would be wise to just see what he says. Just an idea
Thanks for the photos. keep us posted
