Like so? I'll admit my grasp on what kind of armor will stop what is... a little shaky.

Should do. Blooded thought that 6'' could stop 8'' shells, but if this is against the Swiss, I would go for 180 mm for 9'' shells.

Hmm. A 175mm belt costs about two hundred tons, looks like. At 1.1 quality as Maori armor is, that's effectively... 192.5mm.

From NaAB, against the RN's 9.2" (380 pounder), It looks like a belt of 6" or more and a 2" deck would provide at least some immunity zone at right around 20,500 yards. A 7" belt moves the inside of that zone in to around 17,500 yards.

Exactly. And your 15cm belt @ 1.1 is 16.5cm/7". I'd keep what ya got, anymore armor is overkill. She really only should worry about being immune to Swiss/Whoever's CL guns (5-7") which 10-12cm should do fine, especially @ 1.1. (11-13.2 effective).

like the pic on the last page - but really think it illustrates the design is too cramped - with the very poor arcs in particular for the twins right up against the funnels

how about dropping 1 twin amidships - better spacing will give equivalent firepower in many sitns for less weight - 12 gun main battery is still plenty and weight saved can be used for deeper belt or a knot more speed - either would be useful  ;D
