I'm curious how springsharp would report this design. I always use it first before drawing to try and get an idea as to whether my idea would work on it. For example my current battlecruiser concept initially had 14in guns but those wouldn't work with the report so I reduced them to 12in firing a heavier shell and that worked fine.
For that, you'd have to ask Redhorse.
That BB has been posted in his AU since June. All I did, with his permission, was make modifications to the masts, put a different crane on there and added a second funnel. I believe his springshrp report is posted there at that link.
