Oh yeah.  We can sort out those kinds of details if we end up with a deal to discuss.

Okay, the contest is at aend

The Imperial Romanian Goverment chose the Peru submisson to be the winner. Romania will purchase this ship, pending on price.

The Gran Columbian submission was judged too slow and too few main guns, not to mention that the caliber of main guns was way too much. The decisive factor was the speed, 14 knots not being close to enough.

The Brandenburg submission was over all effective, but it was judged to cost too much compared to Romania's budget.

The New Zion/Switzerland(with Desertfox in control of both during the contest  ;D) design was too much of a main battery(I'm trying to stay way from 10'' guns, I prefer 9'' guns)

The Baltic Confederation design was judged to be too expensive, too slow, and have too heavy of a main battery.

The Confederate design was good, and Romania would buy it if Jefgte's price is too high. However, it's main battery was judged to be too little.

The French design was deemed too be underarmed and underprotected for a armoured cruiser.

Er, firepower's a bit on the low side, I only have twins. Though I would squeeze two 11"s on but it was too much. In exchange you have a powerful secondary battery.

I have no access to oil en mass (therefore no oil technology), so you're stuck with mixed coal/oil-firing boilers.

I'm not following the too weak comment... Where is it too weak, considering how you actually gave real feedback to the other ships, this seems quite rude to me. And my coasts are well defended, thank you. I lack offensive capabilities more than defensive.

TexanCowboy

I'm sorry, it's been a long day. :-[

My critisims are as follows: The main caliber of the cruiser is too high, and there are too few main guns. Sorry, I don't really like pre-dreadnought style cruiser armerments. It's also longer then my drydock can support.

Logi

Now that's more like it ;)

See why I hate metric? Here I thought the limit was 400ft, not 120m. :D But I increased the length of the ship cause I thought it would be too tight a fit, oh well.

Cool, I have an other Friend at the opposite side of the world.

If you want a mini BB, Jef's pocket battleship is the way to go.

The French entry wasn't ment to slug it out, but to float like a butterfly and sting like a bee.  The main guns would hurt a BB on the light or non armored places, so, producing a mission kill.

Of course, a Demarce IV would do the job beter, but she's more than twice as heavy.

Jefgte

In Peruvian Building Plan (Excel board), I have a free 120m Slipway in Pisco from 1917H2 to 1919H2

Cost of the Romania 5000t AC - 5BP & 0$

You could pay 1BP or 1.5 or per HY from 1917H1 to 1919H2 -

Mod wet blanket time: a reminder that BP is a capability, not a commodity to be traded. Romania might, of course, build something with it's BP for Peru, but what that is and what ship it ends up going in would need to be specifically detailed.

TexanCowboy

We could make a deal, I could make you 3-4 frigates for that ship. I have the space

I would not be suprised if the Dutch coastal BBs migth fit the bill: http://www.navalism.org/index.php?topic=676.msg23494#msg23494

Hm, that would be in the region of 50-100 000ton of ships then? (15-30kton each).

by frigates, I mean a 1-2,000 ton ship, like a destoyer escort of world war 2

So, not using Dutch terminology then? :)
