[P3D]

- IIRC only Rohan developed/paid for oil-firing boilers, I might not be correct
- Turbine year should be 1909, not 1910.
- Get it 3' shorter to fit into lvl 0 docks
- too deep draft, make it 7'
- no misc weight reserved for the torpedoes
- cross-sectional strength should be 0.50 if we use the wesworld rules

[Earl822]

1)The UKA has been building ships will oilfiring since 1901, and has a serious investment in oil firing
2)Ok
3)zero degree bow here we come
4) 7.5 feet is not very deep, and it is shallower than your Korvettes
5)will sort
6)will sort

this ok?

[P3D]

My korvettes are twice the displacement, 'course they have deeper draft.
See no change, and 230ft is still 10 cm longer than 70m. Know I am picky but still.

Oil firing:
Rohan was the only one who spent some MBP to develop them IIRC. Every single old player can use the same argument you did, and I am not inclined at all to grant this. Use coal with 10% oil bunkers at least in new ships. Start developing oil-firing boiler tech if you want to.

[Earl822]

230ft is as close to 70m as makes any difference.

Will sort the oil firing immediately.

[P3D]

Ty. If every old player start insisting on the tech, I'd have no choice but to grant it everyone.

[Earl822]

Also other than Rohan and the UK/UKA, as far as I know, the CSA is the only nation is the other nation to have invested seriously in Oil Firing.

for the UK to have oil firing at this level would not be unreasonable.

[swamphen]

Up to 10% oil-firing (i.e. auxiliary firing, spraying oil on top of the coal for better combustion) is 'baseline'. More than that, you need the tech.

The CSA also has a heavy investiment in oil-firing (basically, same as Rohan). Otherwise the only 'exception' is Blücher (60/40), which being built in Rohan isn't really an exception at all...
