Carrier Conversion

[The Rock Doctor]

...is that post complete?

[TexanCowboy]

Yes.... I was going to post the modified version, but I though it would be better to see if its even legal.

[The Rock Doctor]

As a liner, she ought to have freeboard of 1/3 to 1/2 her beam - passenger accommodation takes up a lot of space.

[Sachmle]

I see Rocky beat me to it.

Better?

You'll need to tweek the engine year.  The rest looks okay at a glance.

[Sachmle]

This has reminded me, where are the weight/passenger rules for lines now? I can't find them.

[TexanCowboy]

I'll modify the rest later, but it doesn't really affect the total cost of rebuilding. This ship will cost 2.27 BP and $5.24 to rebuild, or $16.24 total. I don't know if I need to add costs for the planes, since I'm actually decreasing misc. weight, not adding. The planes will come from the Air Force.

The miscellaneous weight in the liner is fancy bedrooms and dining rooms, though, not hanger decks and avgas.

So when is the conversion taking place, and how far along is the ship supposed to be at the time?

[ctwaterman]

Im currently working on the Design of the First Italian Float Plane Tender.  I just couldnt afford to put it on to the slips last HY.

Im working on a version of my small tenders converted on the drawing boards to service small aircraft engines and float planes and not ships.   It is in effect a mobile small machine repair shop with extra boats, crew quarters and accomidations, and an armory.   Im sure it can maintain more aircraft then it can carry but any additional aircraft would have to be delivered in crates and assembled where ever it has been set up or flown in seperately.

I will try to finish the SS report in the near future.  I viewed this as a strait up use of the Tender Rules as this is not a functional warship like a real carrier and realistically is very similar to a Submarine Tender, or a Torpedo Boat Tender then a functional Carrier.

[Blooded]

The liner breakdowns can still be found in the 'Old Rules' section/Ship construction post at the bottom of the main page.

[TexanCowboy]

Ok, Rocky, so I add $2 and 2 BP to the cost. The ship has been in service since 1915, I'll tweak that, and this construction will take place in 1/1918.

[The Rock Doctor]

You know, when I said I'd be okay with a conversion, I meant something period appropriate - a collier, or a slow merchantman. 

Do you even have the tech to build this?

[ledeper]

As far as I can see ,no!,since CSA hadn`t progressed longer than :

Aircraft/Seaplane Carriers
1910: experimental aviation ships; automatically granted upon completion of the 1910 Aircraft (1914 models) tech.

[TexanCowboy]

I have 1915, seperate decks. I see this ship in constant refit and repair. And liners did exist. But I gave you the design for approval. Is it all right?
