Ahoj!
With all due respect I think something about your argumentation stinks. Following your line of thought, I can have a raised part of hull, but the guns on it are not raised?
Yes, and no. Guns are mounted at the freeboard level of the mid portion of the ship. If guns are all aft, then all the guns are mounted behind the midbreak, and vice versa if all forward.
Springsharp never places gun on the forecastle, nor on the quarterdeck (or so I have been told). The point is that from springsharps perspective it does not matter were the midbreak is, if it is 60% or 30% of the hull, if a mount is tagged as being in front of this point, the height of the freeboard "forward of midbreak" is used for calculation (such as the weight of a barbarette).

QuoteSS instructions are to mark the fore turret as raised

Correct me if I missunderstood your argumentation, but you say it isn't "raised"?
Yes, that turret is raised as it is above the freeboard at that point along the ship.
But it is also irrelevant, a more relevant example would be Invincible, she have a raise forward of midbreak (some 60% down the hull) should she have three raised turrets?

QuoteI do not wish to offend anybody, but there is something I feel uneasy about.
And please leave flush decked designs out of this, as they are not relevant.
I doubt anyone if offended (or at least I hope that is not the case).
Flushed deck designs are just as relevant, as the mechanics used for simulating them are the same.

Ahoj!
Doesn't the Invincible have a ... lowered quarterdeck?

As an aside - why does Italy have the "thousand tonne can" technology when it's only just become available for research in H1/08?

N2 legacy. Crappy cruisers, but superadvanced in destroyers so that Gravina could built "sploratori".

Borys:

Dreadnought's fore turret was called 'raised' because the turret was not at freeboard level. The freeboard level is where the two beam turrets were located. The fore turret is clearly a 'raised' turret with the freeboard deck running along the edges of the beam.

HMS Revenge, however. has only 1 raised turret forward, as the A turret sits on the freeboard deck. A turret is NOT raised, B turret IS raised. The freeboard deck forward is level with where the gun turret's barbette comes out of the deck, thus, the turret is not raised above the freeboard level.

This is how I understood the SS instructions, and how I build my ships.

As you can see she basically mounts her forward guns raised by your argument Borys however she only lists 4 raised guns.  I would take it that the raised mounts are one forward and one aft however looking at this picture


So either the devs didn't know what they were doing with their own program (I find this difficult to believe) or Kopen and I are right on how we thought to do it.

Ahoj!
After playing WFB and WH40K I testify to developers not knowing what they are doing with their own work :)
OK - you convinced me.

LOL on the 40k thing ill agree totaly, ill have to dig out my army list and post it... 2000 point space marine army that cant loose (well not against anything less than chaos anyway) did you know in a 2000 point army you can deploy  6 whirlwinds... got range =P

Keep in mind that QE design is a botched one, the guns are limited to end on end fire.  Odds are the Y turret should be listed as a below freeboard.  A and X are on the main deck, B is raised and Y is on a lowered quarter deck.

I know I spent 2 hours one day trying to make her work and finally gave up, but then I read up on her and she was extremely unstable.  I think they simd her exactly how she was, Nelson wasn't supposed to fire all her guns in broadside either but did which led to allot of damage to her.  My whole point was that if the devs could do it was most likely an acceptable method of doing it.

I think you are putting the cart in front of the horse. Springsharp give an approximation based on average historical ships. That does not mean that every history ship will sim out as a perfect SS ship. Flipping the trim one stem removes that flag.

And you still have a few things to take into account, springsharp never place guns on the forecastle and quarter deck (Boxes 5&6 and 12&13).
And putting a turret below the freeboard have a few problems, the main one would be that the turret is below the deck and inside the hull, making it somewhat problematic to fire its guns. ... ;)
