Reconstruction thoughts

[The Rock Doctor]

Before I go into the huddle with the other Mods, I need some clarification on the freeboard.

First, I'll note that the current rules set limits freeboard changes to 10%. 

As originally built, the ship's draught + average freeboard is 14.2 metres.  The latest sim adds up to 13.02 metres, but has the hull strength for an increas of some kind.  Also, the old sim has a raised forecastle and quarterdeck, whereas the new sim appears to be flush-decked. 

So if you can re-examine and confirm your ideal intentions, I'll have a better snapshot of what we're talking about.

[Valles]

The raised forecastle and quarterdeck would be razed, then the entire ship permitted to ride 1.3 meters lower.

[The Rock Doctor]

Thanks - note the 10%  limit on change I flagged above.

...so, you're saying that the alteration of forces and structure starts counting from the average of parts... that aren't there any more.

...Well, if that's the rule.

Guess I'll need two rebuild cycles to 'finish', then.

What I'm saying is:  "The rule set is designed to prevent people from building light battleships and turning them into heavy battleships by adding ballast."

[Valles]

...I'm not sure the Bardiches would count as 'light' in any era, but I take your meaning well enough. If I'm over the line in that regard, feel free to mention it. I don't think I'll be able to bring myself to give up entirely on upping their firepower and armor to 'frontline' them again, but 35cm might be more achievable.

Testing an other rebuilt...

Bardiche converted to Heavy Escort Cruiser...

I change the 300mm guns to 250mm guns.
- 2T3x250mm - A & B
- 6T2x250mm - side -2 superfiring
- Reuse the 150mm guns but in twin mounts 1 deck higher.
- Change the engines & increase range & speed to 25kts.

Bardiche Assault, Maori Battleship laid down 1916

Armament:
      10 - 11.81" / 300 mm guns (5x2 guns), 823.82lbs / 373.68kg shells, 1916 Model
     Breech loading guns in turrets (on barbettes)
     on centreline, evenly spread, 1 raised mount 

I'm curious, what is the Main Battery layout of these? I'm thinking A/Q/Y and 2 beam turrets (like "Dreadnought").

[Valles]

18x250mm was and is, indeed, one of my runner-up concepts, Jef, in case of more extensive alterations getting scotched. There'd be some differences in how I'd do it - I'd probably stash the 150s for use in a later escort cruiser, and go with 100mm for a secondary battery, given that the 250s would be 'handier' than full-on 300mm battleship guns, for instance, but something like that is, indeed, in the realm of possibility. I'd prefer to avoid it because turning her into a cruiser-hunter, however potent, seems like a waste of a battleship's tonnage to me.

Elf, the main battery layout of the 'battleship drafts' is one I've been almost desperate to do, all centerline with A and X and a pyramid Q(R)S midships.
