My friend Cliff's GB/DD/1906 design

My friend Cliff designed the British destroyer he intended to mass produce. It had these oddities, in that the ship had 2-88mm QF guns (20pdr) and 2-21in TT, which were anacronistic. The main benefit of the 88mm was that it had a high rate of fire and the shell was easy to manhandle. The designed speed was 32 knots. In Springsharp, the design came out with a very low displacement, in order to obtain adequate seakeeping ability. The machinery was 55.7 SHP/ton of machinery.

The drawing of the Ger/CB/1906 design

I now have the drawing of the Ger/CB/1906 design online. You can click on the small picture to see the full-sized drawing with detail. This is the design that was nominally 25,000 tons with a speed of 33 knots, with 8-12in/45 and 12-4in QF guns, and 4in side armor.

My original concept for the Ger/BB/1907 design

I just tried my original concept for the Ger/BB/1907 design where the speed was just 24 knots. I had estimated in 1971 that 54,000 SHP was be sufficient. The Springsharp calculation is 56,740 SHP, which is pretty close, considering the methods I was using for estimation in 1971. I had to increase the draft to get sufficient hull strength, but otherwise, I was able to get a good result with Springsharp without much effort. The machinery basis was 25 SHP/ton:

The start of my building program for the Germans

In my building program wargame with my friend Cliff, we started off from a standing start in 1905, with no ships on hand. We started a purely naval war in 1914 using what had been completed by then. My building program started off as follows:

• 1905

1. 3-battleships 8-12in/45 and 12-4in QF speed 23 knots 10in belt
2. 1-battlecruiser 4-12in/45 and 12-4in QF speed 31 knots 4in belt
3. 6-scouts 5-4in QF 2-18in TT patch of 2in armor speed 36 knots
4. 12-destroyers 2-4in QF 2-18in TT speed 32 knots

• 1906

1. 1-battleship 8-12in/45 and 12-4in QF speed 23 knots 10in belt
2. 2-battlecruisers 8-12in/45 and 12-4in QF speed 33 knots 4in belt
3. 6-scouts 5-4in QF 2-18in TT patch of 2in armor speed 36 knots
4. 32-destroyers 2-4in QF 2-18in TT speed 32 knots

• 1907

1. 3-battleships 8-12in/50 and 12-4in QF speed 24 knots 13in belt 3in deck
2. 6-scouts 5-4in QF 2-18in TT patch of 2in armor speed 36 knots
3. 16-destroyers 2-4in QF 2-18in TT speed 32 knots

• 1908

1. 4-battleships 8-12in/50 and 12-4in QF speed 24 knots 13in belt 3in deck
2. 6-scouts 5-4in QF 2-18in TT patch of 2in armor speed 36 knots
3. 4-destroyers 2-4in QF 2-18in TT speed 32 knots

After 1908, I introduced some new types into production. For those ships that I list here, I have profile drawings for each one that I will be putting online. With Springsharp being available, having a building program game is very much a possibility. It is more satisfying if you have someone else designing the building programs for other countries.

More ship drawings

I have finished a number of ship drawings done in this high-resolution GIF style. What I have done are all German ships from my designs done in 1971 for the warship design and building program game. To date, these are what I have done:

1. Ger/BB/1905
2. Ger/BB/1907
3. Ger/CB/1905
4. Ger/CB/1906
5. Ger/CS/1905
6. Ger/DD/1905

I have done Springsharp designs for all of these that I have posted here.

My friend Cliff's British Destroyer design: GB/DD/1906

I had to make a few adjustments, but my friend Cliff's design for a British destroyer worked fairly well in Springsharp. The main issue, as always, was achieving acceptable seakeeping ability. I increased the draft and decreased the block coefficient until the seakeeping was over 1.0. The odd features of the design are the 88mm (20pdr QF) guns and the 21in TT. Cliff thought that is the 88mm was good for landwarfare, it should be as good at sea, even for the British:

I firmly believe in Frank Fox's dictum to draw the inboard profile first, before drawing the ship was it was sit at the waterline (outboard profile)

Right now, I am working on an inboard profile of the Ger/CS/1905 design. I have a new domain, which is not up and active, where I will be posting ship drawings and data for my ship designs. I have long had the concept of putting together Janes Fighting Ships-type presentations. Ideally, you would have photograph like pictures of the imaginery ships, as well.

My latest attempt at the GB/BB/1906 design

I just tried my friend Cliff's design for a fast battleship with light armament, the GB/BB/1906. It really went together easily, once I went for a SHP/ton of 29 SHP/ton of machinery. The ship has 6-12in BLR and 8-6in QF guns, all in twin turrets. The ship has a long forecastle with twin funnels. The armor is thick, with a belt and turret faces of 13.4 inches. The revised speed that I had hoped for in 1973 is easily attained, as I did not want a very great range.

The German scout Ger/CS/1909

This was my scout design for 1909 for the Germans. It was inspired by the large Italian destroyers. The armament is 4-5in QF and 2-21in TT. The speed is very high, being 36 knots. That made achieving a balanced design all the more difficult, although it could be done (SHP/ton of machinery weight being 48.76):

OK, so the scale is actually 2pixels to the foot

I see that my actual drawing scale is two pixels to the foot, for my GIF drawings. I am currently working on a drawing for my German Ger/DD/1905 design. I am starting, as Frank Fox advocates, with an inboard profile, so that I know that I have the internal layout correctly depicted. Do an inboard profile, as Frank says you should do first, regardless if you are drawing an early 20th Century Dreadnought or a 17th Century sailing warship. That assures that decks are the right height and that ports and so one are placed reasonably. Otherwise, you run into what most of the artists on the Springsharp forums, do: they just draw, and disregard the internal layout (seemingly).

To really see the drawing in the last post, you have to work at it, I'm sorry to say

The obvious downside to the drawing I just posted, is that you have to click the picture to see the larger size drawing, and then view at a larger size, because the one-pixel lines disappear, until you see it at full size (nasty thing).

Cross-published with Former-Naval-Person

This is my first attempt at a higher resolution GIF drawing that is done to scale. I was amazed at how readily I was able to produce something that I thought looked good. I had been inspired by the GIF drawing on a Springsharp related forum showing the USS Texas rebuilt along the lines of the Italian Conte di Cavour. While I thought the drawing didn't account for the internal layout required, I still thought that the drawing was technically well-executed, and I realized that I could do something similar.

The main problem with posting Springsharp reports are that they are so wide

The most bothersome thing about posting Springsharp reports is that they "go off the edge" into the dark background. The good news is that you can copy and paste the whole text, for those who are interested. I may end putting my new high-res drawings on Kentishknock.com, as it where I have most of my more formal drawings. I have thought about putting the whole building program from the game in 1971 there, with specs and drawings.

Another try at my Ger/DL/1914 design

The design of the Ger/DL/1914 was inspired by the German ships, some built for Russia, that had three stacks and 4-4.1in guns, with 6-TT. By taking care of the SHP/ton issue, the design works well. A drawback of the basic concept is that it is low-volume, above and below the waterline.

I just finished the raw drawing for the Ger/BB/1907 design

I have my initial drawing, done as a high-resolution GIF file, to scale (1 pixel = 1 foot). I hope that I will be able to color the drawing, much as the example drawing that inspired me to try drawing this way. I just started the coloring process, and can see that it will work. I just have to fix these odd light blue and green pixels that are artifacts of converting to GIF format and then resizing the drawing to the 1 pixel to the foot scale.

I've been working on improving my ship drawings

The drawings in the forums associated with Springsharp are invaluable to me. I've switched to GIF format and thinner lines. It really helps the quality. I'm working on a drawing for the Ger/BB/1907, based on a sketch I did from last year. I hope to have it ready to post by tomorrow, sometime.

Yet another run at the Ger/DD/1905 design

So, by going to higher power output machinery, I can make my F-class like design for a German destroyer for 1905 work. The ship was intended to make 32 knots and have 2-4in QF and 2-18in TT. That should be a pretty conservative design, only marginally edgy on speed.

The Swift achieved something like 64 SHP/ton in trials

When the British large destroyer Swift in trials, circa 1907, she produced about 50,000 SHP on a machinery weight of about 781 tons (420 tons boilers and 361 tons turbines). That comes out to about 64 SHP/ton. Admittedly, she was pressed to produce that much power, and she was so overweight that she was only good for 35 knots, maximum. I wanted to point this out, though, so that if you had concerns about high power output per ton of weight, it is not out of line.

Back to the bizarre: the super fast (Alternative-2) battlecruiser

So, what is the best I could do, with a relatively short fast battlecruiser? I took my "Alternative-2" design for the 192x super fast battlecruiser, which has a high-freeboard, flush deck, with a modest clipper bow, with a good deal of flare. I was able to achieve 40 knots, but had to make some sacrifices to do it.
