My friend Cliff had this concept for a lightly armed battleship

My friend Cliff liked exploring the fringes of warship design. One concept that he had was for a battleship armed with two triple 12in turrets and having relatively thick armor (in this case, 14in). I have an annotated pencil sketch for what I think may have been considered for construction starting in 1909. It could have been earlier, but I have my doubts. I don't have speed data, but with Springsharp, I found that we had underspecified the armor and had too low a freeboard. The design tends to be wet forward, according to Springsharp. This is the report:
