Normally, you round up on SM, so that would by +12 (which is why I use the fractional ones)

Physical size, at 294 yards, it would be up to SM +13 according to that. You could call it SM +12, since it was long, but it was very boxy...nothing like something like a fast battleship (Iowa classes were as much as 60k tons, but a little shorter, and a lot more svelte).

Yup. Guns and armour are heavy, and so is the structure to support them.

Comparing the numbers from Wikipedia, Titanic was midway between Iowa's standard and max tonnage, almost identical in length, and slightly narrower abeam and had lesser draft.

But Iowa had a clipper bow and raked sides, whereas Titanic was a floating apartment building (or, being British, a block of flats).
