Speaking of overlooked polar ships, what of "Fram"?  I have fond memories of seeing her, and the viking ships, when in Oslo.

 

Ian,

     I took a look at Fram. Every time I read about these expeditions, I have a flashback to Butch Cassidy and the Sundance Kid - "Who are these guys"? That is one tiny ship to be taking on an expedition to the South Pole - 128 feet. Discovery is half again as long and carried three times the crew. Amazing. I will note that there is also an MS Fram that does cruises to polar regions and a SpaceX mission called Fram that is due to launch this year and have a polar orbit.

 

So, an update. I've made some progress installing the second set of planking, but realized that I didn't order quite enough of the correct size of wood, so I will need to order a bit more. As can be seen in the photos of my last entry, the second planking does not cover the totality of the ship's hull. For example, it runs to the bottom of the propeller shaft as can be seen on this excerpt of a photo from the Scott Polar Research Institute (original here: https://www.spri.cam.ac.uk/picturelibrary/catalogue/article/p83.6.2.3.2/)

 

 

At the bow, the ship is double planked at least to station 3 on the plans, which makes sense as there is an iron ice breaker attached (this is courtesy of a document sent to me by the Discovery Cove Museum in Dundee:

 

 

Or this close up (source Google Maps - full photo credited to Open Virtual Worlds)

 

 

As I mentioned, when I plotted the cutoff points using the sections, it produced a lower line that did not correspond with the photos as shown, so I did my best to come to terms with the variation in a fashion that would seem to make sense and produce a reasonable looking result. This yielded the following lower limit on the double planking, as seen from the above:

 

 

You can see where the double planking isn't complete, but it shouldn't take a ton more lumber.

 

Here is the ship from both sides. I haven't really sanded it yet - will do that once the double bottom is done. In the interim, here she is from both port and starboard:

 

 

It's amazing how much neater the second planking goes on - get a solid surface, and thinner stock and things go on really easily.

 

I will put the bulwarks in while I'm waiting for the rest of the wood. 

 

One question for the experts out there. This is a barque with a 450 hp steam engine. She carries 3 masts, 2 square rigged, each with a course, split topsails, and a topgallant (so 4 yards per mast) and a fore-and-aft mizzen. Discovery has relatively narrow, non-built masts - much smaller in diameter to the massive built masts on my last ship, the Flying Fish. I was wondering about why they could get away with masts like that, and had speculated that a clipper like that would carry a lot more canvas (I mean the Fish had 3 square rigged masts with course, top, topgallant, royal, and skysails) plus all of the clipper extras (studding sails, ringtail, etc.). However, when I look up the size of their rigs, we find that the Fish carried "8250 yards of canvass [sic] in a single suit." The Discovery had a sail area (in 1901) of 12,296 sq ft. So, is the 8250 "yards" square yards, or is there some arcane convention that can be used to convert to square feet? Crothers goes into great detail on these ships about everything but their sail plans (which I realize changed a lot over time). Any help greatly appreciated.

 

As always, thanks for looking in!

"Who are these guys" indeed. It was known that driftwood from Siberian forests was sometimes found in Greenland. Fram was specially built with an egg-shaped u/w hull to withstand being trapped in ice; pressure would just lift the hull not crush it. The plan was to sail north from Norway and get as far as possible before being trapped in ice, then just sit there and wait for the ice drift to take them to the Greenland area via the north pole (?!!). After a long while (a year and a half? two? can't recall the details) it became apparent that they were on a trajectory to miss the pole by a large margin, so two men, Nansen and Johansen, decided they would take some of the dogs and sled to the pole then attempt to rendezvous with the ship at an estimated future position....they reached over 84 degrees north, some 150 miles north of the then record, but ended up missing the ship on swinging back and had to return south on their own (again, ?!!) in a 15 month ordeal of sleeping in a rotting reindeer sleeping bag and other misery until bumping in to another expedition. There is a great book, unbelievable reading on the level of Shackleton's Endurance expedition, entitled "Farthest North" by Fridtjof Nansen. Riveting reading.

The hull is looking mighty fine George. 

[davyboy]

Hi George,

 

If I remember correctly from my schooldays 7 decades ago 1sq yard is 9 sq ft,3 x 3. That would give RRS Discovery a sail area

of Approximately 1,366 sq yards. Re your flying Fish multiply the 8250  sq yds by 9 and you have your sq ft.

I think/hope I've got that right.

George, I took a look and yes indeed Flying Fish is recorded as having 8250 "yards" of canvas, but as canvas came in I believe 3-foot wide "bolts" to be sewn together into a sail, each "yard" of a yard-wide bolt is in fact one square yard. Vastly larger than Discovery's sail area.

Ah, that makes sense, it's the length of a standard bolt! Following your lead, I see here: https://textileranger.com/2017/12/05/a-compendium-of-sail-information/, that "Standards for British manufactured sailcloth were enacted in 1746.  In addition to requiring British sail makers to mark each new sail with his name and address, the size of a bolt of sailcloth was standardized at twenty-four inches wide by thirty-eight yards long", and Wikipedia says 23 inches wide in the US and 24 in Britain. Still that gives us a range of:

 

23 inch yards: 8250 'yards'*1.958 ft/"yards"*3 = 48,468.75 sq ft.

24 inch yards: 8250 'yards'*2.0 ft/"yards"*3 = 49,500 sq. ft

36 inch yards: 8250 'yards'*3.0 ft/"yards"*3 = 74,250 sq. ft.

 

As you say - VASTLY larger, 4x at a miniumm. An acre is 43,560 sq. ft. so the Fish had more than acre of sale at even the lowest size bolt. I wonder how many acres of cotton or flax would be needed to make that much cloth.

 

Amazing.

GAK

What about poundals and slugs, in the past measurement units had character, not like this modern SI unit stuff! 

[Rick310]

Beautiful job on the hull, George!

Are you using basswood for the planking and what is the thickness of the 2nd layer of planking?

Rick

[FlyingFish]

According to wikipedia SI units are: "a result of a decades-long move towards increasingly abstract and idealised formulation in which the realisations of the units are separated conceptually from the definitions". Can't imagine what could be wrong with that.

Great build George!

Thanks Rick! The wood is bass, 3/64 by 1/8. The bulwarks are going to be made from 1/32 by 1/8 planks with 3/32 stanchions.

Ain't that the truth. You need some number of base units, and I don't have an issue with the meter, the liter is 1000 cm3, the second and volt were pretty much universal. But this proliferation of named units that don't tell you what they are measuring: webers, grays, bequerels, sieverts, grays, teslas, etc., etc drive me nuts. I mean I know what they measure because I remember some of my physics,, but I would have to look them up to see how they mapped to base units to use them mathematically (not that this has been much of a problem since I took physical chemistry in grad school, but still).

 

And with that I will ask those annoying neighbor kids to get off of my lawn, and move on.

 

Regards,

George

[Dr PR]

The metric system is far superior to random noggins and farthings, but the "abstract and idealized" definition posted above makes about a much sense as inches, feet and yards.

 

I too despise the meaningless names - especially "famous man" monikers - used for the units. Changing from the logical "centigrade" to "Celsius" was pure stupidity.

[KeithAug]

As a measure I like feet. I have two of them.

[gak1965]

I swear that this will be the last I say on the subject of measurement. But - if you haven't seen this, it's worth the five minutes:

 

 

Now back to the ship. I found some extra wood in my stash and mostly finished the hull planking, so I hit the hull with some gray primer to see just how much sanding is required. Answer is definitely some. However, I'm going to do that one time after the bulwarks are in place, so that is the next step. On the ship in 2024, the planksheer and waterways are a dark brown, as are the bulwark stanchions with white bulwarks. In 1901 it seems like the bulwark stanchions were white, with a planksheer and waterway that were the color of the rails. If you look below the lashed poles in this photo you'll see the waterway:

 

 

And here is a photo of a stanchion:

 

 

Given this, my inclination is to paint the planksheer, the interior of the bulwarks, and and the bulwark stanchions prior to installation and then painting the exterior of the hull. My initial thought was to stain the planksheer, but that was not a huge success. Even with pre-treating it, it was very blotchy, and I think that the problem was that I got glue on the wood during the installation of the planks. I tried sanding it a bit, but no dice. In the end, I found some paint of a similar color to the oak stain I'm going to use on the covering board, and said time to move on.

 

 

Next step was to make 77 stanchions. 75 of them are 3/32 in square boxwood, painted white on 3 sides (the final side is left unpainted to adhere better), cut to a length of 1 inch, with a mark on the unpainted side 1/16" from the bottom, and 2 are just 1/2 inch longer. Similarly, I took 1/32 by 1/8 basswood strips, and painted one side white; these would be the bulwarks.

 

 

I then installed them into the pre-cut holes in the planksheer. Most of Discovery's bulwarks are pretty vertical - I made a little jig to help with the locations that are not. This yielded an arrangement like so:

 

 

 

I then started mounting the basswood strips, using the stanchions to define the curve of the bulwark. Once I reached the height that I was aiming for (in this case 5/8" or 45 inches at scale, I clipped off the top of the stanchion. Here it is from the outside.

 

 

And from the inside:

 

 

Once the bulwarks are done, and the hull sanded, I can mask off the bulwark tops and paint the outside. And this way, I don't have a lot of spillage of the bulwark planks on the planksheer.

 

Anyways, I think in a couple of weeks, I will be able to paint the exterior and it will start looking more like a proper vessel.

 

As always, thanks for looking in.

 

Regards,

George

[gak1965]

The bulwarks are continuing apace (I will put some photos up when they are completed), and that has me thinking about one of the big questions about the hull - namely, what color is it below the waterline. But first, I was in Philadelphia on Monday moving one of my kids from a horror of an apartment to a much nicer one. We went out to the Ikea on Christopher Columbus Way to buy her a small table, when I was very surprised to see the SS United States. Probably for the last time before she goes to Florida to become an artificial reef.

 

 

It's sad to see her go, but off hand, I'm not sure that anyone has the money to really save her. The funny thing is that the ship seemed small, which it is not (I mean the ship is 990 feet overall with a beam of 101.5 feet, and a height of 144 feet from standard load water line to funnel. But compared even to the smaller modern cruise ships (we took a trip on the Holland America ship Konigsdam in 2017) the Big U doesn't have the same amount of bulk. I'm not complaining - her lines are fabulous, but it's still something of a surprise at the difference.

 

Anyway, on to the color below the waterline. The historian at Discovery Cove in Dundee responded to my inquiry, but if the color was recorded, they don't know where. I've been looking for something akin to Duncan McLean's Boston Daily Atlas (there do seem to be a small number of digitized newspapers from Dundee, and perhaps someone mentioned it in a news story about the launching). The historian did however point me to a collection of construction and launching photos (https://www.dhtcollections.com/item/Brand_SYDiscoverybuildandlaunch_0_0_26347_74.html). They are, of course, black and white and more than a bit ambiguous. Here are some of the key photos (or more accurately portions of them).

 

Launch day:

 

Another view of launch day:

 

In the water:

 

When I look at these photos, I'm just not seeing any obvious indications that the bottom was anything but the same color as the rest of the hull - black.

 

Now here are two post-launch photos of Discovery in drydock:

 

 

 

and one from Australia:

 

 

and one from Dundee:

 

 

The photos from Dundee seem to show a different color at the highest Plimsol line, although the modern ship is not painted that high. The ship had (has) metal ice breaking material on the bow - could that be what is the slightly different color up to the upper Plimsol mark? As to the bow on picture in drydock - could that just be salt (or wear) with the ship running at the standard load water line? 

 

I'm starting to think that the correct color is black. And I note that Endurance appears to also be painted black below the waterline as seen in this Paget color photograph by Frank Hurley:

 

Any thoughts welcome.

 

Regards,

George

 George, I wonder if the black paint below the waterline is a different hue/flatter in color because of antifouling agents added to the below the waterline paint?

That could be. The ship is a bit odd in a bunch of ways because of its purpose/mission. For example, the foremast (which has the same size yards as the main) uses hemp rigging (and tied ratlines) vs. metal rigging for the main, presumably because they needed to keep iron away from the magnetic observatory which is aft of the foremast. Clearly there was iron/steel on the ship, but it would have been kept away from the observatory (supposedly the original wardroom upholstery had to be replaced with a version that didn't have metal buttons). 

 

If I understand, the primary biocides would have been copper based, but the primary source of color for red paint in those days was iron oxide. Add the copper and it changes the hue somewhat, but don't put in the red to avoid slathering the ship in iron oxide?

 

It's an interesting problem.

George

George, the quote below is from an MSW build log, post #17, see link. Evidently black antifouling paint was available in 1901,

 

 

 

Posted September 20, 2016 (edited)

"According to an old textbook on marine engineering (Steinhaus, 1870), antifouling paints were available at that time in a variety of colours, including reddish brown, green, black, white, yellow, and blue. Basically, you just add the pigment of your choice. Their biocide effect was based on inorganic lead and in particular copper compounds. Concerns over heavy-metal contamination in harbour muds and the search for a higher efficacy led to the development of tin-organic compounds. However, these are being phased out since the 1990s, when it was discovered that they act as 'endocrine disrupters', meaning that they lead to malformation in aquatic animals that come into contact with them. The problem is that antifouling paints not only act toxic to things that want to stick to a ship's bottom, but slowly wear off (which is part of the antifouling process) and become dissolved or settle in particles in marine sediments. Here their toxic or endocrine disruptive actions continue. I believe in more recent years antifouling paints put more emphasis on non-stick properties and slow wasting that detaches whatever tries to held a foothold.

 

I gather red(dish brown), green, and black were generally preferred colours, because these resemble the appearance of either coppered or tarred ships bottoms. Muntz-metal bottoms would have looked yellowish to green-greyish, depending on their age. The Austrian navy actually used a pinkish paint on their iron and steel hulls before WW1, btw.

 

Appart from being a waste of money, paint may not stick very well to copper because of the oxide layer that forms rather quickly on its surface. The picture in the first post is not very clear and I don't know anything about the vessel in question, but would it be possible that a protective sheathing of wood was applied on top of the coppering for travelling in areas where there was floating ice ? This sheathing in turn may have been painted."

Well, another update. First the ship. The bulwarks are done, as are the bulwarks that enclose the forecastle. Two images. The first image is after the first sanding of the primered hull. As you might expect it's pretty ugly as it removes the primer on the 'high' parts of the hull:

 

 

After sanding and with a second coat of primer:

 

 

The second coat of primer looks much better than the first at application. There are still areas that need some filler, and sanding, but it's definitely starting to shape up. BTW, I painted the bulwarks white on the outside to seal any gaps where leakage won't damage the inside. Hopefully when I put the black on the bulwarks it will stay on the outside where it belongs.

 

As to the colors. I've been doing additional research, but haven't found anything definitive yet. Via the British Newspaper Archive, we find the following report from the Dundee Evening Post on 21 March 1901:

 

ANTARCTIC SHIP DISCOVERY. 

LAUNCH THIS AFTERNOON. 

A large assemblage of spectators was present iu Panmure Shipyard this afternoon [to] witness the launch of the exploration vessel Discovery. The building of this interesting craft has occupied little over a year, the first section the keei having been laid in the early days of M-irch last year. It is expected that the rigging and fitting out operations will occupy the best part of six weeks, and she will then proceed London for stores. Several members of the expedition party reached Dundee yesterday, aud, indeed, Professor Gregory, of Melbourne University, was the principal absentee. Invitations were issued to the following Sir Clements R. and Lady Markham; Sir Reginald Ogilvy, Bart.; Sir James Low Lady Low; Mr and Mrs G. W. Baxter; W. Thomson; Mr I. J. Weinberg; the Hon. J. C. Higgins, TJ.S. Consul; Mr E. Maitland; Mr and Mrs W. H. Fergusscn; Mr and Mrs W. Low; Colonel Cautlev, R.E.; Colonel Baillie; Captain R. F. Scott.. K.N., commander of expedition, and Mrs Scott; Lieutenant Armitage, R.N.R.; Lieutenant Royds, R.N., Mrs Rovds and Misses Royds; Mr R. She! ton, R.N.; Keltic; Dr Koettlitz (scientific staff; and Mrs Koettlitz; Mr George Murray, British Museum (Professor Gregory's deputy); Mr C. Longhurst, secretary National Antarctic Expedition; Mr H. W. Smyth, London; Dr Hill (scientific staff); Mr R. Paterson, manager, Panmure Shipyard, and Mrs Paterson; Mr G. E. Kidd. secretary, Dundee Shipbuilders' Company, Limited, and Mrs Kidd; Bailie Barrie; Treasurer Ritchie; Lord Dean of Guild Bell; Captain Wilson Barker, R.N.R.; Captain Montgomery, R.E.; Commander Austin, R.N.; Surgeon Brown, R.N.; Captain Abbot Anderson; Professor D'Arcy Thompson; Dr and Mrs Bruce, Edinburgh; Mr A. Leitch and Miss Leitch, Dundee; Mr and Mrs R. Leitch: Mr and Mrs Rettis; Mr Thomas Winton; Air John and Miss Henderson; Mr and Mrs Wilson; Mr and Mrs J. P. Newton; Mr H. G. Gourlav, Mr Charles Gourlay, and Mr J. G. Lyon (Gourlay Brothers & Co.); Mr Grant Barclay (Caledon Shipbuilding and Engineering Co.. Ltd.); Mr William Morrison and Mr Howie, Lloyds' Surveyors; Mr A. Watt, Board Trade .Surveyor; Mr F. Stephen; Mr F. W. Emmet; Mr Bartholomew, Edinburgh; Mr Stuart Gray, Kuitauns; David Bruce, Loudon; Mr I). Wyllie, Dundee; Mr B. L. Nairn; Mr William Kinnear; Mr R. V. Scroggie; Mr James Mitchell, and the local whaling captains. 

 

DECORATIONS AT THE HARBOUR. 

In honour of the occasion bunting was plentifully displayed at the harbour. The whalers, needless to say, were prominent in their decorations. Every vessel had a streamer of bunting to the mast-head, and an appropriate touch was to be seen in the case of the North Pole vessel America, where the Stars and Stripes floated alongside the Union Jack, the mission of the America compared with that of the Discovery being literally "wide as the Poles asunder." The flagstaff's at the dockgates were also gaily bedecked, the whole going to make up a bright and animated picture. 

 

THE LAUNCHING CEREMONY. 

For the purposes of the launch huge staging was erected close the stem of the vessel, and to accommodate the launching party a platform about ten feet square had been erected a few feet in front. A barricade had also been placed about ten feet from the side the vessel to keep back the spectators, and prevent them hampering the workmen in the discharge o[f] their duties. The attendance of spectators was unusually large, and it is estimated that the time of the launch there were about 3000 people congregated within the Panmure Yard. They began to gather shortly after one o'clock, and little after two nearly every position from which a view of the approaching launch could be obtained was occupied. At the Marine Parade the crowd was especially dense, and great difficulty prevailed in keeping them in order. 

 

SHE'S OFF. 

By three o'clock everything was in readiness. The gangway leading to the ship was cast on, and thos[e] who were booked for the " maiden vo[y]age" the Discovery gathered on the forecastle, and from their high perch watched the preparations for the christening. The launching party appeared about, quarter-past three. Sir Clements Markham, Lady Markham, and the other distinguished guests being the centre of .attention. The party having taken their position, Mr Paterson, after seeing everything was in readiness, gave the older to the men who were in waiting with hammers in hand. A brisk hammering then took place, and the shores supporting the vessel tumbled to the ground. A slight pause was then made, during which Lady Markham let go the bottle of wine, which, encased in a bouquet tied with the tri-coloured ribbon, was swung cords from the forecastle of the Discovery. The bottle struck the bows, but, to the surprise of the spectators, who expected to see the vessel glide away, she remained fast. It then transpired that the easing operations had not been completed. A minute two of tension followed. More brisk hammering then took place, and the cry broke forth —" There she goes." The vessel, indeed, had begun to move. Gaining speed, she rushed on and with terrific splash the Discovery took the water. The tugs Renown and Excelsior were in waiting, and at once took her in tow. She was berthed in Victoria Dock, where she will be engined. A luncheon was held late in the afternoon. 

 

AN IMPORTANT LETTER. 

The following letter has been received from W. E. Smith, chief constructor for the Admiralty, a gentleman who designed the Discovery:—

 

The building of the Discovery is unique a character that much more than the usual interest attaches to her. Usually when vessel is required to built there no difficulty obtaining tenders from large [nu]mber[s] of competent firms, any one of which might safely entrusted with the work. The Discovery, however, [is] of [n]o usual character, either as regards the material of her construction or regards her design. A large number firms were invited tender, but the tender from the Dundee Shipbuilders Company was the only one that indicated any real determination to grapple with the difficulties and novelty of her design if opportunity were afforded. It might perhaps have been anticipated from the past history and experience of the firm that they would not flinch from the difficulties of the case, but the fact remains that stood foremost in the breach and undertook to build the without, which the [e]xpedition could not be undertaken. The firm having accepted the responsibilities involved the building of the vessel, once set. work in the actual construction of the ship, and have vigorously and continuously prosecuted that work ever since, and have endeavoured their part nothing undone that could contribute the seaworthiness of the vessel or the comfort and convenience of those board: and there firm in the country having greater knowledge of what, necessary in the[s]e particulars for this type vessel than the Dundee Shipbuilders Company. 

 

In the interests of the expedition [I] have, [I] am afraid, been sometimes exacting, but I [am] most pleased to say that have been very handsomely met, and my work has pleasant one. desire particularly thank Mr for the very great interest he. has taken the work and the skill in which has executed it. I am much indebted to him for many useful suggestions, the adoption of which will make the ship more efficient than she otherwise would have been. I [am an] old wooden shipbuilder my[s]elf, and I must congratulate the firm on having in their [ser]vice yard foreman the qualifications of Mr John Smith, who has, under Mr Paterson's directions, so thoroughly attended the actual work of building. I hope w[e] live to s[e]e another Discovery launched, and that the Dundee Shipbuilders Company will again ready undertake the work they have [ris]en [to] the occasion.

 

Nothing about the color of the ship unfortunately.

 

Similarly from the Aberdeen Journal (same day):

Again, nothing about the color.

 

[As an aside, the article mentions, and I've seen photos, that she carries a balloon. I was going to model the gas tanks (stored above one of the after deck houses, but a tethered balloon might be more interesting yet.]

 

However, I have concluded that there must have been some different color up to the top Plimsol line. Here is another photo with an apparent color change.

 

The most common colors were red and green. It has to be something that doesn't use iron oxide based pigments, so that suggests either red lead (which apparently uses lead II|IV oxide as a pigment, or verdigris (copper II oxide), or emerald green (copper(II) acetate triarsenite or copper(II) acetoarsenite). The arsenates and copper compounds would act as antifouling agents on their own.

 

Bottom line is that I need to make a decision, and probably pretty soon. I'm now thinking I'll make it green or red, without boot topping.

 

Thanks for looking in and for the likes!

 

Regards,

George

Your build is coming along very nicely.  Interesting historic account if the launch, especially the style of the writing.
