laid down 1916, conversion to blimp tender in 1928

The Lamia and Tronagarru are converted Tankers identical to the Sea Lark class tankers in naval service.
The Sea Sprite and Seam Mermaid have been purchased from civilian yards following a failed building contract and will convert along similar lines to the Admiralty class destroyers, albeit on a larger scale to handle large rigids and scouting blimps.

The CL's a bit slow - is it intended more for escort work than independent action? The secondary battery's light for Wesworld, but quite reasonable compared to historical.

The DD shows quad TT versus the implied triples. I'm also seeing more AA guns than listed.

The tenders are interesting. I kinda wonder if the proximity of the moored blimp to the blimp tender's funnels might be a problem. Maybe the exhaust should be trunked to some exhaust ports near the stern?

Good pics all round.

She is indeed more of an escort, smaller designs will follow for more independant action.

Yeah I noticed the torpedo's AFTER I posted the pics, never caught the AA though, thanks for the catch!

The blimps will normally not be positioned that way, they are recovered from the stern, the blimps do however need enough room to swing around and not bump into anything which is what the drawing depicts.
Reguardless the funnels will cause some problems but the design overall will provide experience for improved designs.

The small hangar like structure is for the storage of the Blimps gondola and deflated canvass balloon.

Might want to add 20 or 30 feet to that mast on the big tender. Patoka's final mast height was about 170 feet above the waterline, heightened from 140. Right now you only have about 20 foot clearance between the control car on Atlantes and the midships derricks.

Monday, August 1st 2005, 5:58am

I find that ammusing given the fact that I shortened the mast slightly for asthetic purposes! I can always add another center section to the mast.

I also have to modify the base of the aft derricks as they seem kind of flimsy.

Good pics Wes.

I see you aren't paying the premium for high speed with your ships. The new leaders look a little under-powered (or are they pushers?) ; )

I see you've also given up on seakeeping for that cruiser. However she could take quite a battering.

I think on ballance, reasonable armour, 12-6" guns and 31knt speed on only 8000tons and you've invented the stubby Mogami.

Cheers,

*Cough cough*, I think everyone (including myself) failed to notice the discrepancy between the Cerasus class CL's SS file and her drawing, she has a flush deck in her drawing, yet the SS file states she has a raised forecastle. Chalk it up to a seemingly endless design process......

With slight retooling of both the SS file and the drawing heres the design, any thoughts?

Good Grief! I can't even keep my ships straight, much less someone elses! :)

But she shouldn't have a raised forecastle. She should have a rise before the midbreak to sim her correctly. SS assumes that light guns only are mounted on the forecastle and quarterdeck.

Damnit keep hiting the wrong tags!

In the second drawing she definately has a raised forecastle, in the first shes flush decked.

Personally I like the first drawing, but making her flush decked completely fudges the design.

Perhaps I need a clearer definition of the terms, now you have me confused!

Send an email to Ian about it. He should explain it. I lack time to draw out a diagram.

Did you copy Wes's data, Gavin? Or did he secretly edited your post?

O_O

Stem: 25.50 ft
Forecastle (at 20 %): 24.50 ft
Forecastle (after break): 24.00 ft
Mid (at 40 %): 24.00 ft
Quarterdeck (at 15 %): 14.00 ft
Stern: 14.00 ft

At 20% you have a 0.50 feet break.
Between mid (40%) and quarterdeck (85%) it gradually goes from 24 to 14 feet. There is no break at either point.
So shouldn't the 10 foot break be at the mid point?

Yes. I should read;


Stem: 25.50 ft
Forecastle (at 20 %): 24.50 ft
Mid (at 40 %): 24.00 ft
Mid (after break): 14.00ft
Quarterdeck (at 15 %): 14.00 ft
Stern: 14.00 ft

Since Wes is the last one to have edited your post, should we assume that he is the main suspect?

No secret editing. See, "Damnit keep hiting the wrong tags!".

Was something erased?

I assume this is a discription of what the original design should read as.

We assume that it has been replaced. :-)

Well, the original freeboard looks a bit... odd (or at least I think it is).

I've PM'ed Ian so I'll chalk this design up to "disinformation" for now till I sort it out.
