Better to have a separate thread for the new navy like Jeff and Darman are doing instead of posting it all in one thread that might end up looking quite disorganized...

First one is the oldest (I think) 'operational' vessel planned for the Norse Navy. Not going to be useful but just there for fun. :)
As the vessel is circular (and will have its issues), the diameter is 101 feet so a 101 feet main belt is not going to give proper protection so that is where the 58 feet ends belt is for (as SS3 freaks out if I go over 101 feet with the main belt). The bottom 8 feet of the ends belt is the extension of the 9" main belt and thus 9" thick. The top 5 feet of the ends belt is the extension of the 5" upper belt and thus 5" thick. I added the weights that SS gave me for both extensions and got a 7.5" thickness for a belt of 58x13 feet to sim that particular combined weight.

The OTL one had 11" guns, but I do not have that one planned for the Norse Navy so I had to go for either the 305mm guns or the 250mm guns and settled for the latter as the raised guns meant that it was going to be a bigger issue to solve when going for the bigger guns...

... and since I have Belfast, I got to have these for the White North Star Line even if they are not crossing the Atlantic... which, considering what happened OTL, is probably not a bad thing...

No Royal Mail to worry about so no RMS designation is used for the Norse Liners. If I got it right with the Norwegian wiki pages, Steam Ship would be Damp Skip so DS instead of SS. Also Norwegian does not seem to be using the 'c' the way the English do so while I decided to use the names of British ocean liners as they are, a 'c' would either be an 's' or a 'k', depending on the sound (so in case of the Olympic, Titanic and Britannic Nordic, it would be Olympik, Titanik and Nordik).

A slightly more modern vessel than the Monitor, based off the British Topaze class...

NNS Topas, Norse Protected Cruiser laid down 1903

   - Armoured deck - single deck:
   For and Aft decks: 1.75" / 44 mm
   Forecastle: 0.75" / 19 mm  Quarter deck: 0.75" / 19 mm


So conceptually, that's a flat 44mm deck with no side armor to keep shells from going over or under it.
I'm guessing the Topaz had a protective deck, with 2"/50mm slopes and a .75"/20mm crown.
Which would likely weigh less as well.

Looking at the wikipedia pic of the PC cross section in MS Paint, you only require about 5% extra beam to cover the extra bit of armor for the protected deck that is needed because it slopes down like that. Another thing is that that image suggests that the center ~40% of the ship's beam is thinner (though that could vary slightly depending on a cruiser's beam).

Assuming for simplicity with my sim that the middle part is half the simmed thickness, that would mean that 40% of 40 feet is 16 feet. Half that means you get 16 feet of 0.875" thick while the remaining 16 feet I will fold in two to 8 feet and add back to the 60% bit. 60% of 40 feet is 24 feet. 16 + 8 + 24 = 48 feet. 48/40 = 1.2 meaning that if it were all horizontal, it would cover an extra 20% of beam while the image told me only 5% extra was needed.

Looking at those results, I really do not see why it is necessary to sim a 12ft high belt of 1" thickness and an additional bit of 2 feet of 1.75" thickness to sim that what the deck armor can also do if you use a bit of imagination.

Simplicity.
If it's right there in the sim, and we know what that piece of armor means, then all that is required is simple addition to find the thickness of the slope.

Further what I'm suggesting is what several of us talked about in N6 - sim the protected deck at whatever thickness, then add a short main belt to indicate the additional slope thickness.  In the prior conversation I believe 2.44m was settled on as that is 1 default deck height. For my sims, I'm using 3.66m.

Armour:
   - Belts:      Width (max)   Length (avg)      Height (avg)
   Main:   2.56" / 65 mm   437.99 ft / 133.50 m   12.01 ft / 3.66 m
   - Protected deck- single deck: 0.98" / 25 mm For and Aft decks
   Forecastle: 0.98" / 25 mm  Quarter deck: 0.00" / 0 mm

Very easily indicates a protected deck that is 25mm on the flat and (25+65) 90mm on the slopes.

Otherwise we'd have to sit down and replicate your math to find out what your decks actually are. The greater the beam of your vessel, the lower the % in slopes.
Now what you don't seem to be addressing is your beam is only the widest part, your vessel tapers, but the angle and distance of the downward slope of the deck should not greatly vary. Which means the proportion of flat middle should decline as you approach the ends of your vessel.

QuoteSimplicity.
To me it is a lot simpler to just enter the deck thickness and be done with it. The calculation I did above shows that it should properly cover it with half thickness on the center flat area.
QuoteVery easily indicates a protected deck that is 25mm on the flat and (25+65) 90mm on the slopes.
Well, the protected deck curves and no longer reaches the sides of your ship that way. I had tested it with a deck 0.75" thick with a 12 ft high 1" thick upper belt and to complete it all the way to the sides a 2 feet high (which I screwed up as it should have been 1 feet as 5% of 40 feet is 2 feet and I forgot to divide that by 2), 1.75" thick main belt as the curve requires an additional 5% of beam to be covered when it is assumed to be a flat surface. There was only a 0.01 difference (and probably no difference if I had used the correct main belt height of 1 feet) between doing all that complicated stuff and just simming the deck as 1.75" and assume that it is 0.75" in the center and 1.75" on the slopes. 0.01 is not enough to make it worth all the extra effort which could be much better spend on checking the sim to see if there are no errors in it when it comes to the number of guns per mount for example.
QuoteOtherwise we'd have to sit down and replicate your math to find out what your decks actually are.
Why? There is no need to if you assume that the center part of the ship is protected by half the simmed deck thickness and the slopes are the given thickness. Don't make it more difficult than necessary. Just keep it simple.
QuoteThe greater the beam of your vessel, the lower the % in slopes.
The lower the % in slopes just means that there is going to me more 'leftover' armor from the higher % thinner center part that you 'remove' to be 'placed' on the sides so I don't think much will change. The same is probably true for narrower beams as well. Probably enough so for anything down to destroyer beams.
QuoteNow what you don't seem to be addressing is your beam is only the widest part, your vessel tapers, but the angle and distance of the downward slope of the deck should not greatly vary. Which means the proportion of flat middle should decline as you approach the ends of your vessel.
I feel that the extra 20% beam coverage should be enough to cover the ends where the flat area is much smaller. Probably in the same way that you assume that the extra bits of the belt that are not needed at the ends cover the gap between the ends of the protected deck and the sides that would exist because of the curvature of the protected deck.


If you want to keep simming the Protected Cruisers your way, I am not stopping you. To me it is too much hassle without any gains or losses to apply it. It would also make it look a lot like one of my light cruiser designs with that main belt at which point I am thinking "Is it not just better to use that sim as a light cruiser sim instead of a protected cruiser sim?"

Kaiser Kirk

Interesting stuff.
Not sure if I should take ending line as "I'm done with this" or not.

However, I do see that I didn't explain a bit very well.  So not to offend, but I'll take one more try at explaining.

1) The prior conversation decided on 2.44m as that seems to be a default deck height level.  You'll notice I'm using 3.66m on my ships as that is the slant distance at 45deg. While I am using 2.5m/deck when calculating things, a slightly steeper slant would make 3.66 work. Still not 100% accurate, but fairly close.

2) "The greater the beam of your vessel, the lower the % in slopes." is the part I mucked up. The correct version is the lower % in flat.

Take 3 sections, roughly forward, amidships and aft
     _ _ 
   /      \ 
  _ _ _ _
/            \ 
   _ _ _
  /        \

While the distance occupied by the sloped portion of the deck doesn't change, the flat area does.
As a result, when considering the overall vessel,  A greater % is taken by the sloped portions than a simple evaluation of the midships cross-section would show.

Anyhow, you are correct, how to model this is not part of the ruleset or gentlemen rules and so up to the individual player.

I will stick to my original observation that a protected deck is fitted at the waterline and curves under the waterline, while an armored deck is fitted above the waterline, and so the way your design was originally presented, there was a flat deck that shells could easily dive under.  That is a simple toggle fix, much like going from single to twin mount...except no comp hull issues.

Quote"The greater the beam of your vessel, the lower the % in slopes." is the part I mucked up. The correct version is the lower % in flat.
Odd... to me you had it right and muck it up with the correction.
QuoteWhile the distance occupied by the sloped portion of the deck doesn't change, the flat area does.
... and this would confirm that the greater the beam of your vessel, the lower the % in slopes and not the flat. After all, the flat area becomes wider and wider the closer you get to the widest part of the ship and the wider it gets, the greater the percentage of the beam of the ship it becomes.

Not sure how it works on real world protected cruisers, but with the way you do it, slopes coverage does not change if you stick to ~12 feet so with a 60 ft wide Parthian Protected Cruiser, the percentage of beam that is part of the slopes is less than the percentage of beam that is part of the slopes of a Parthian Protected Cruiser with a beam of 40 feet.
QuoteI will stick to my original observation that a protected deck is fitted at the waterline and curves under the waterline, while an armored deck is fitted above the waterline, and so the way your design was originally presented, there was a flat deck that shells could easily dive under.
Yes, it should be protected deck. While it makes no difference, it just looks more correct to do so. *makes note to check the deck armor on all ship designs*
QuoteThat is a simple toggle fix, much like going from single to twin mount...except no comp hull issues.
I deliberately mentioned the guns because I know from the experience of making the exact same same error that you suddenly need extra hull strength for those guns and you need to do a lot more tweaking of the design to get it correct again. :)

That is what really bemused me, when I corrected it, I went from 1.00 comp hull to 1.02... I was expecting like 0.96.

*checks SS*
Oh yes. I see that my issue was the same but reversed, where singles were simmed as twins rather than singles.

Having been thinking about it, while a few navies feel that some proper ventilation is needed due to the location of their navy's operational area, I need to tweak my designs a bit to incorporate heating systems on my vessels.
