Small Orange ships and MWVs

[The Rock Doctor]

If you're still with the "Advanced: 1905" engines, then your powerplant is too big (4000 hp/shaft).  I'm also not sure if you can really get three shafts on a hull that small.

[Borys]

Ahoj!
Pretty!
I see nothing to whine about :)
For once!

And I see that Rock has better eyes!

If you're still with the "Advanced: 1905" engines, then your powerplant is too big (4000 hp/shaft).  I'm also not sure if you can really get three shafts on a hull that small.

There were RN destroyers of the size having 2-3 shafts.
SS is attributing too much power for the relatively limited speed. The first Tribals on similar power made 33kts.
I know it is my design, but even if it weren't I'd allow it - a 10% difference.

[The Rock Doctor]

So 4,000 hp/shaft is more like a guideline?

[P3D]

My main intention was to have a limit on capital ship/cruiser speed. If I installed four shafts, with inefficient small propellors, I would be well below this limit. Originally there was an additional turbine tech after the first one. I might raise max shaft power to 5000HP, so the difference from the next tech won't be as enormous - would that make you happy :) ?

[The Rock Doctor]

That would be fine - I'm just making the point that the tech levels need to be concrete - no slippage.  Otherwise, there'll be lots of slippage.

[P3D]

True. At least myself should conform with the rules, at least as I can change them  ::).

The coastal minelayer/sweeper of the Orange Navy eqipped with some experimental oil-firing boilers. Engineers swear it would work.

I want to get some fst destroyers in the water, not only battleships. Here's one with oil firing. A coal-firing version is available, with 3000@10kts range, and one less 4" gun.
The TTs are on the sides, and there's no reload.
Ships are carrying a small 5t wireless - enough for short range communication. The squadron flagship has a 10t wireless set at the expense of 4 torpedoes.

Already read those pages, and about everyting else on that site :)
But my bases and basing is much superior to what the Netherlands had historically.

Hu? were did those come from, i was under the impression that it was at least 10 tons or non for a radio set?

[Carthaginian]

It's definitely the smallest listed set, and the one that I designed my new DD's around.
Had I know that we could install a smaller one and get even 25 miles out of it, I'd have used that.

[P3D]

Even the 10t sets are in  the misc weight allowance.
