Here is the Combat Cruiser Valandil from Rohan.
This cruiser was built in 1906-1909 & sold to Gran Colombia at the beginning of 1917
Gran Colombia didn't use this kind of cruiser & proposal to made a transfer to Peru.
The cruiser "ll be transfered mid 1917.The Armada Design Bureau is studying the cruiser to adapt to standard Peruvian Armada characts.

I draw the cruiser with Rohan building look but Tan could ask for modifs.
Jef ;)
Looks good to me Jef, I wish I could do as well on overheads as you do...
Nice. Any chance that you could do a version with the cage mast that I think Ithekro would have designed her with?

I could redraw with a cage mast.
1 or 2 cage mast?

nice solid ship - you plan to upgrade engines? - seems to be only the speed that is really out of date
very well protected but suffers for it - stability is a bit low
Quotenice solid ship - you plan to upgrade engines? - seems to be only the speed that is really out of date...
no plan for update engines.
- The speed is correct to work near the BBs.
- I have seen probably a little bullet.

2 shafts for 46000SHP in 1909... I probably correct & change to 4 shafts

What is the best choice to increase stability ?
- Remove 4 x229 casemates guns
- Add bulges, reduce speed
...

Reducing speed actually decreases stability since you have less engine weight in the lower parts of the ship (something that will also happen if you are going to throw new engines in there). So it should read: "- Add bulges,
increase speed and keep an eye on the seaboat rating" :)

and get rid of the gagworthy cage masts...
Yes. tear them down and send them back to Rohan so they can use them as giant Braziers to light their coastline. :D
I like those cage masts. Keep 'em!
Yes, until a hurricane strikes your Atlantic strike force. Then, your fire control masts go down, and I attack in the chaos. ;D
Yes, it's my Achilles' Heel.

Rocky, you forgot your [sarcasm][/sarcasm] HTML brackets. Shame on you ;)
What can I say - I like to keep people on their toes.
Jef, what software do you use?

I use an old PCB software, just the library part.

Here is AC Manco Capac
ex Valandil enter jan 1918 in Callao Shipyards for modifications to standard of the Peruvian Armada.
- New 230/45 mlle 1916 take the place of the old 9"/42-Mlle1893
- New 120/45 mlle 1905 QF take the place of the old 4"5/42-Mlle1891
-New 40MlleAA 1916 take the place of the 38mm from Rohan
- Cage mast are removed & the classic circular light top blockaus take those places & not so high.
