NUS Light Cruiser for 1913

[The Rock Doctor]

Figure a mine per tonne of miscellaneous weight set aside for the purpose.


I'd suggest just going with one triple bank on each side, at the second funnel - this is primarily a gun cruiser, it seems, and too many torpedo banks are going to interfere with firing arcs.

Alternately, I suppose, you could raise #4 mount and place it on an extended platform forward of the second funnel - then put a bank of fish under that platform.

Here's another pic w/ and overhead view. I moved the lifeboats to deck level and IF the TTs rotate on the aft axis they'll clear.

Not to be picky, but is there a crane to get those boats over the side?

[Sachmle]

Rope, sweat, and the fact that if they don't get them over they're probably dead will cause the crew to propel the lifeboats into the water.  ;D


Fine. Picture a small crane on each side of the 2nd funnel, angled towards the boats.
Better yet, here's an updated pic and an SS w/ weight for the cranes.

There was this layout, SS report may come later. It worked, but I didn't like the looks so I deleted it. But anyway, I think it looks to modern.

You don't need misc weight for boat cranes.

That last one looks cool! If you don't mind I might have to borrow the drawing for when I get around to building New Zion's first cruiser.

[Jefgte]

The last drawing is good.

You could add some lifeboats on the deck under gun 5 & 6.
The cranes are too short to put the lifeboats in the sea.

I do not really think she look too modern. But if you made the funnels higher and thinner she would look older. But she put me in mind of some of the german light cruisers from the end of ww1.

I very much agree with Desertfox, cranes for boats do not require misc weight!
Nor for that matter do I think any normal fitting such as climatization, quarters for crews and command, signal flags, boats, derricks, davits, cranes, machine shops, toilets, provisions and extra paint need to have misc weight dedicated to it as I see some people are doing.

[The Rock Doctor]

I'll provide for such fittings if I feel it's in excess of the normal amount for a ship of that size.  For standard loads, I assume it's just part of the "hull, fittings, and equipment".

[Jefgte]

I agree with you for the material inckued in
"Hull fittings, and equipements"

Meanwhile, some ingeniors in modern naval concept think that Springsharp is a very good approach for calculate warships at.... 95%.

IMHO, add 5% of light displacement in miscellaneous weights is good for the real feasibility of a warship.



Jef  ;)

[Sachmle]

As of right now this is the version that will get built. I realized that at 425' she would tie up my only type 2 dock, so I cut some 6", made the TTs centerline mounted, and chopped off some of the misc weight. Same hull dimensions as the Union class before her, but 3 more 6" guns, each w/ 100 rounds more per gun, and 2 more TT w/ the same speed and 250nm more range.

For comparison sake, one can see that the Toreador is more of a evolution of the Union as opposed to a whole new design.

Ahoj!
Excellent! Fantastic comparison
But I'd still advise to grab the shovel ...
