A lot of gun for size... top weight issue, is strong in this one

Sharp counts it normally.
Top weight of Salamis and Espana was not so smaller...

Would you mind showing the Springsharp report? It's not a perfect tool, and at times it takes some time to get into it, and learn which elements it simulates poorly. And it does seem odd for Springsharp to accept these numbers.

Nice to see more battleships,
Regarding the last what's the date 1912 or later and should there be 2 raised mounts?

Because she laid in 1913
Quote:

Mount "Y" is half-raised (on one level with turrel "A"). It can shoot over the "Z" turrel only with some angle of elevation.
