I already have Reclones, so that's why I went with the 3x3 36cm design. With the 12" design, I was looking a bit at Alaska +1 turret and the 11" a bit at Scharnhorst +1 turret.

What's the intended function of the Oguras?

I'm suprised Brock forgot. He's usually the one reminding me how many you have.

I didn't forget. Just observing that this class, like the other class, is somewhat Renownish in armament.

While I have tried to start with it in the past, I thought I'd give Photobucket a proper shot last weekend. Made this borrowing bits here and there and using 'numerous' photos as well as the small linedrawing in Talbot-Booth's Merchant Ships vol. 2. Loosely based on the Shell Tanker Acmaea and her sisters...
http://www.helderline.nl/tanker/95/acmaea/

I'm planning to use it for a '43 IJN fleet tanker.

Fantastic drawing!

But I'll reserve judgment on the design as a fleet tanker until I see the Springsharp.

It is kind of like your Deutsche Werft Typ 3, tough a tad bigger and a bit slower.

When I was walking home, I realized I should sim the freeboard slightly different so I will redo that (when I manage to stay awake).

<puts down Merchant Ships 1958>

Yes, I suppose that she would be close in size to a Typ 3; I guess it is the drawing that makes her look longer, and the streamlining of a commercial tanker. In terms of construction technique, there's not much to quibble on her later launch date. Certainly doesn't look Japanese, but she does look good.

She does indeed. I think that's a factor of the streamlining on her superstructure.

Should have posted it sooner, but either I was busy with work or busy killing people with the game Way of the Samurai 4 (needed to kill 1000 baddies in order to get the +250 attack "Oddity" title for my sword)...

In order to sim the bridge island in the middle, I looked at the sim with the bridge island being part of the quarterdeck. I wrote down the average freeboard and after having returned the sim back to the previous settings raised the mid point (freeboard points 8 & 9) until I got back to that average freeboard. That's the best I could come up with.

I would think it is less complicated than the octuple 40mm mounts I used before on various ships.
