Sadly, this just kicks the inevitable can down the road. Digital media also has a half life. The only way to perpetuate information in any medium is to recopy it before the reading-writing technology becomes obsolete. There is the story about a well-known ancient British history book (The Domesday Book) that was digitized in a proprietary format, involving an immense amount of time and resources. However, within just a few years the digital format became obsolete, negating all that work.

Wow, Julie, what an intro! You seem to be what they called a polymath in back in the day. If you need any assistance with getting started in DELFTship, I may be able to assist. It's very good for developing fare hydrostatic hull forms but it bogs down when creating lots of fine details. Terry

You should visit the many threads in this CAD/3D Forum that address your question. For basic hull creation from plans, I believe that DELFTship Free will produce the most faired and smooth results. Then export the resulting model into other recommended programs to create the details.

Those guys all look pretty buff!. Aren't there any striplings in your crew? 🙂

And digital is even more forgiving and takes up zero space in the livingroom!😉 Terry

Nice! This configuration shows her several years after I left the boat. Terry

On submarines, we always slid down the main stairs between decks on the handrails with hands only. You controlled your speed with your grip. I even saw our COs do this on occasion! For vertical ladders, there were always hand grips positioned somewhere above the top rung to help the transition between ladder and the deck.

Hi Wefalck. Thanks for the pointer. In Underhill, Figure 44, there is indeed an image showing the lower topsail yard supporting rod/stay/strut. This is in the context of an iron and steel-sparred ship. The figure shows the upper end of the rod hinged to a hefty lug at the bottom of the center band, as stated earlier. The hinge plane was in line with the yard and vertical. The lower end of the rod terminated at the steel cross support at the base of the topmast. Scan from Figure 44, page 39, Masting and Rigging the Clipper Ship & Ocean Carrier, Harold A. Underhill, Reprint 1969; Brown, Son, and Ferguson, LTD Interestingly, all the diagrams of the LTS yard (including Fig. 44), show the LTS yard mainly supported by a swiveling crane arrangement, rather than the universal-jointed truss as in the lower yard (and as was the case for Galilee). So a crane plus a support rod for the LTS yard seems to be overkill except, perhaps, in larger ships. I finally found a side illustration of the LTS yard strut in Underhill, Plate 16, on page 80 (there is so much information buried in this book that it is easy to overlook things!). The plate illustration suggests that the lower end of the support strut is simply an eye-in-eye swivel, bolted through the forwardmost top platform crossbeam. So, lacking any other information, that's what I will go with. Plate No. 16, Ibid, showing the arrangement of the LTS yard support stay or strut. In Galilee's case, the entire weight of the LTS yard, hardware, rigging, and sail rests on this one rod! When the yard tilts, I'm still not sure how that motion is accommodated by this support system.🤔 Thanks for the prodding! Terry @wefalck @BANYAN

This is a plea for input from the general membership to identify the depicted iron hardware shown below and/or for direction to a source that illustrates (or at least describes) this object: What's it? The upper end of the rod is attached or hinged to the centerline band of the foremast lower topsail (LTS) yard. The bottom end of the rod is somehow attached to a cross-brace in the decking of the foretop platform. (Courtesy Carnegie Science Library, September, 1906) The ship it was used in was the US West Coast merchant brigantine Galilee, built at the Matthew Turner shipyard in Benicia, California, in 1891. The reference photos I am using are mostly from the period when the ship was chartered by the Department of Terrestrial Magnetism, Carnegie Institution, Washington, DC, between 1905 and 1908 for geomagnetic data collection in the Pacific Ocean basin. Captain Matthew Turner, by all accounts, was the most prolific shipbuilder on the West Coast during the latter 19th century, and he frequently incorporated in his wooden sailing ships innovations that were common to iron-masted sailing ships during this period. I have a variety of other images, all together indicating that this isn't some kind of running or standing rigging ropework. It's always absolutely straight and typically runs in a direction at an angle to all the other lines in its vicinity. At this point in the ship's life, virtually all iron standing and running rigging had been replaced with hemp in order to minimize the rigging's magnetic effect on the ship's instruments. Only structural iron that was absolutely necessary for the operation of the ship was retained. Other images: Various depictions of the LTS yard support rod. (Sources: left and right, Carnegie Science Library, c. 1905-1907; center, SAFR, prior to 1905) Any assistance would be greatly appreciated. Terry

I just noticed this problem tonight (3-Jan-25), but I was trying to add an image to a PM and noticed that all the usual buttons in the gray bottom margin for selecting and inserting images and attaching files to PMs and topical threads are missing. I can't even include a screenshot because this post is also missing the image/file controls. Is it MSW or my browser/computer? Terry

Yessir, to virtually any number of decimal places you desire in either imperial or metric units. I use Blender mainly as a free 3D CAD program after Sketchup was no longer free to hobbyists. As others have mentioned, Blender has a steep learning curve, but there are helpful, experienced users in our community. Terry

Or you could move to the Dark Side for free and try 3D printing using the Blender extensions.🙂

Brings back memories as a young USN air intelligence officer doing ship recognition briefings for the carrier pilots 'way back during the Cold War. Kotlins and Kashins involved in "shouldering" incidents in the Med. Krestas shadowing the CBGs. Fun times--not!

CCClarke, please see my PM. Terry
