[The Rock Doctor]

I started developing 275mm guns because I was contemplating something rather similar.  I was even looking at the same name for a ship, since it'd be a Jamaican boat.

[Jefgte]

A Panzerschiff cousin  ;)

Engine 1916... That mean that Avenger 'll commissioning in 1918.

the Pships were its insperation, although im not 100% sold on her just yet (id like 30 kts), Rock Avenger is just a working name (if I build em ill name em more along traditional cruiser type names aka city names)

[P3D]

You can design the same ship with 1912 engines.

[Tanthalas]

You can design the same ship with 1912 engines.

I have and posted it previously, I intend to build one or the other.

No worries - I just thought it was an interesting coincidence.

11' quarterdeck freeboard seems inadequate for the Pacific.

11' quarterdeck freeboard seems inadequate for the Pacific.

IDK It was more for aperance purposes than anything, I always have a lowerd Quarterdeck.  Not etha tit can be raised to a flush deck ship with no negitive effects.  anyone else think its to low? I may have to do a bit of research to see.

IMO SS2 underestimates the freeboard needed for longer ships. Look at historical designs, freeboard was usually much higher than what SS2 deems sufficient for 'good seaboat' rating.
For destroyers it is the opposite.

added a PIc of her (scale is 2 pix = 1 foot) I think Photobucket squished it though

Please explain deck shape to me ...

Quite nice ship, BTW.

Also, which engine tech does NS have? Are you limited to 20,000 SHP?
