Looking good, Sjors. Given the Aggie was a war ship, I sure hope you don't have any whales on the deck!!!! I can just picture Commodore Sjors sending men out onto the bowsprit with harpoons - "Thar she blows, me hardies - boats away! She breeches now - prepare the broadside with harpoons and nets! Steady now, lads, thar be only the one shot - ready the chase guns!" Yep - the Aggie takes to the south Pacific in chase of the Great White Whale Moby Dick! Oops - sorry about that...got a bit carried away!

Good afternoon, one and all. I hope that all are doing well. Attached is an updated version of my nautical resources This first file is primarily PDF format files that can be found on the internet (link included whenever possible). Note that not all are free (some may require a subscription to a site or publication). Waynes Nautical Listing 22 April 2015.pdf This second file is primarily printed books (though a few PDF documents did sneak in). Waynes Nautical Books 22 April 2015.pdf As this is a work in progress, there are some obvious typographical errors and formatting issues in some of the listings that I will work on as time allows. Please let me know if you have any questions!

Nice recovery, my friend! The details you put into these are absolutely mind boggling (however, before you get a swelled head, it does not really take much to boggle my mind....) As to our Dutch friend and his IRL - I suppose that is better than the other Dutch word he taught me Pfffffffffffttttttt! Cary on - we all wonder what is next! :im Not Worthy:

Gripen 1591 by NAZGÛL (Matti)
trippwj replied to NAZGÛL's topic in - Build logs for subjects built 1501 - 1750
Looks good, Matti - I like the design you came up with. Mind if I lurk in the back here and enjoy the build? -
Your work, as always, amazes me, Denis. I am sitting here suitably impressed - I do need to ask, though. Will there be any fish laying about the deck, and do you ever feed your workmen? They are looking a tad malnourished....

Seeking information on determining load waterline
trippwj replied to trippwj's topic in Nautical/Naval History
Bruce - Thank you for this - you have summarized quite neatly many of the areas that I am trying to dig into in order to understand this transition to pre-determined draught (I am using draught here as meaning the level on the vessel that she is designed to float when fully burdened. Measured from the base of the keel) and displacement! I pulled some of your observations from your post and provide some partial responses - I still have a bunch more work to do! LWL is a nice to have, easy to draw, but very difficult to predict. That is really the basis for my project – at some point, it became Need to know, not just nice to know, and thus a component to the design of a ship. For example, as the gun port came into use, it became important to have adequate freeboard – to keep the wet stuff a safe distance below the openings into the hull. While an existing vessel with adequate freeboard could serve as a model for the current generation, ships grew over time and the shape changed, so that what was good before no longer applied. early design drawings were to the inside of the planking so that the builder can use them for directly laying out the frames. This is true – since the primary purpose was to determine the shape of the frames. However, since the thickness of the planking was generally known (either “institutional knowledge” or specified in the requirements), adding that to the dimensions was an easy step for the designer. Given the large uncertainty in the as-built weight and weight distribution of a large wooden vessel, I suggest that the only method of prediction is how a hull of similar form and construction floated. This is a good point, and an area that I am gathering more information on. Some of the earliest treatise (British) discussing the determination of displacement (and draught) use “plug numbers” to come up with the weight of ships to then try to determine both the ballast required to reach a desired draught and the draught itself. Since all ships carry a significant weight of cargo, the final water line for profitability, stability or best sailing trim is determined by the ship's officers. This has always been an issue – many of the officers during the days of sail had a tendency to over-mast vessels, resulting in poor sailing qualities and reduced stability. There was also a lot of fidgeting with ballast and stores distribution to alter the trim to that desired by the master – sometimes to the detriment of effective performance. A good case study would relate to the early American frigates, where the Secretary of War basically threw up his hands and directed that each Captain and Constructor should mast the frigate as they saw fit. Some performed much better than others…. Half-hull models could be used to determine displacement; and builder's models could help with center of gravity. There was actually an attempt to do this, although it failed miserably since building a model of true scale (not just dimensions, but also weights and trim) was not possible, and model testing was rudimentary and not an accurate indicator of 1:1 build performance. Among the interesting research papers I have come across is one from 2008 entitled "Technical Writing in English Renaissance Shipwrightery: Breaching the Shoals of Orality" by Elizabeth Tebeaux - well worth the read if you get the opportunity! -
Looks great, sir! Stay with the green - she would have likely carried synthetic nets, and it looks great!

I suspect that the additional items listed are the additional plans mentioned in this part of the description (very bottom of the description section) The timbering plans are sold separately from the set of plans from the book and provided within another cardboard cover to the same format. These may be provided at the 1/48 scale upon request.

Specifications for Construction of U.S. Navy Ship Models
trippwj replied to Rob Wood's topic in Nautical/Naval History
Yep - the term in question is defined by citing the term to be defined as the definition! It was interesting to do a web search on the term "museum quality ship model" and see this lengthy listing of retail websites selling museum quality ship models (or even kits tagged as museum quality). I think I'll stick with building mine to the horse at a gallop standard.- 16 replies

Specifications for Construction of U.S. Navy Ship Models
trippwj replied to Rob Wood's topic in Nautical/Naval History
In 1980, Mystic Seaport published the, “Ship Model Classification Guidelines″ - attached. Includes some 1961 specifications from Howard Chapelle at the Smithsonian. In its simplest terms, “Museum Quality Model” means that a model has been built to a set of standards as set forth by a specific museum with regards to scale fidelity, materials, methods, research, historical accuracy, and so on. Or, as has been pointed out above, 'I don't know art, but I know what I like'. I also like this description - 'A museum quality ship model is whatever a museum director accepts for a museum collection' ship-model-classification-guidelines-1980.pdf- 16 replies

I can only speak for my current Emma C. Berry build - the instructions called for doing the interior ceiling before the exterior. I debated, but found it made sense - in order to get the exterior planking correct, the covering board along the top of the frames needs to be installed. This, in turn, necessitates adding the deck beams first. Once the deck beams are in place, working space on the interior is very restricted. As to "real world" practice, I have seen both approaches described.

Spectacular work, Ed. Those detailed figures are impressive!

Thank you, Frank, but I think I'll take cold and snow over hot and parched. John - thank you for that warning! I need to check that before I put the last couple of beams in to be sure I haven't created more challenges! Than you, Mobbsie - will keep you posted on progress! One interview thus far, but didn't get the position. Will keep looking, though!
-
Thanks, Augie - moving forward, keeping spirits up. Gotta be something better just over the horizon! Thank you, Lawrence. She is certainly no match for your Annie, but she is a fun build! Thanks, David. Got a dusting of snow last night and again this morning, but the snow is slowly but surely melting. Only 30 inches or so (on average) left to go! Thank you, Grant. It was tough to get motivated, but moving along now. Reorganized the shop today, cleaning out my old office to convert into a bedroom.

Superlatives fail me, Denis. You will need a small bottle of bubbly to christen this beauty- she looks so real! Well, sir, as Bob's your Uncle I am looking forward to the next steps - are you weaving your own nets?

Greetings - and please accept my apology for the lengthy delay between posts! Between the snow onslaught in January and February and then my employment change last month, well, it has been rather difficult to get motivated to spend time in the build yard. Most of the progress shown was from January. I am trying to get my enthusiasm back to move on with Emma and hope to be splitting time between a side research project, the job search and the build table. At any rate, the deck beams are nearly all in - 3 more major beams and a few cross pieces to add. I have opted not to do the knees - I tried a couple of times but they did not come out well at all. View from above Profile view. Note the very low clearance in the forward hold! The cabin will have a overall height just above the worker standing there. Next up is install the last few deck beams and then start planking. Suggestions desired - and thanks for stopping by!

While it is a British treatise, this may be of some use to you. A Manuscript on Shipbuilding, Circa 1600, Copied by Newton Transcribed by Richard Barker in The Mariner’s Mirror, 80, 16–29, doi:10.1080/00253359.1994.10656481. http://dx.doi.org/10.1080/00253359.1994.10656481(Accessed February 16, 2015). The document presented here came to light as a result of an item in M.M., 40 (1954), 73, one of an occasional series of lists of Records. Thanks are due to the Librarian of the Cambridge University Library for permission to publish the text. It is catalogued as MSS Add. 4005 Part 12, presented by the Fifth Earl of Portsmouth, described as being in Sir Isaac Newton's autograph c.1700. The description masks what this writer was delighted to discover, in an idle moment: that the manuscript is a copy of one or possibly two earlier documents, parts of which clearly date from about 1600. The section of this manuscript on proportions of masts and yards is manifestly (and almost verbatim) the same as the Scott Manuscript (RINA No. 798). Otherwise the general style and content of these two manuscripts are broadly similar, in respect of the processes of moulding, for example, but in no sense are they direct copies. In fact this new manuscript contains a more coherent description of some details of ship construction than can be found in the Scott MS.
