Thank you Dr.Batchvarov wishing you a enjoyable,interesting and productive field season.
Thank you very much!
I have long appreciated the books by Howard I. Chapelle.
He is a good author!
As always, thank you my friend!!! Well done!
Thank you very much!
Thank you for another enjoyable and accurately informative conversation, Dr. Batchvarov! I've only recently discovered your interesting series of videos and greatly appreciate your efforts producing them. As a long-lived life-long avocational maritime historian and consumer of maritime archeology, albeit primarily focused on the quite narrow subject matter of American small working craft and yachts, and, correspondingly, as a modeler of similar subjects, I find in you a kindred spirit. I haven't the time left in life to acquire another doctorate, but your video presentations cause me to fantasize about what my life would have been like had I been able to spend as much time in your classes as I did in those of my law professors. Certainly, I wouldn't have dozed during your lectures!
Too often I've felt like a salmon swimming upstream in waters polluted by the current "kit modeling culture" and, I might even say, "reviled" by some for criticizing the sacrifice of academic standards of historical inquiry, research, and analysis on the altar of the Almighty Dollar by all too many kit marketers. I believe I am in good company, though, finding reassurance in Jean Boudriot's observation in his foreword to Bernard Frolich's "The Art of Ship Modeling," where he observes that to be a good ship modeler one must thoroughly immerse themselves in the historical maritime milieu rather than simply competently assembling parts according to a set of instructions. Your videos provide those who were not taught how to "access" that antiquated "information platform" called a "book" in an accessible digital format a valuable exposure to the academic consciousness of the maritime milieu Boudriot found prerequisite to serious ship modeling.
This is not to say that ship model kits cannot serve as the "gateway drug" to what may for some become an excusable addiction, nor that well-executed high-quality kit models cannot be things of great beauty, but, to my way of thinking, the highest value of a ship model is in the history we can learn from studying it. Regardless of how many steps it may take to produce it, there's a world of difference between a "paint-by-numbers" version of the Mona Lisa and the real thing! This is, of course, a philosophical issue best further explored over a strong drink or three.
With reference to your instant video, I thought a quotation from L. Francis Herreshoff in his book "The Commonsense of Yacht Design" regarding the origin of the conventional "east facing" orientation of naval architectural lines drawings might be of interest to you:
"It is customary to draw the bow facing the right hand, or east side, of the drawing, and this custom came from making a model first with the stations laid off on its centerline reading from left to right, but when the model was turned over and laid on the drawing (to draw the pencil around to get the sheer and profile) then the station numbers read from right to left. Some designers have the yacht facing either way; my father (Nathaniel G. Herreshoff) did about as many one way as the other."
Thank you, sir, Those bewildering lines (and their names) now make perfect sense.
Excellent! I am glad it was helpful!
Nice Cad rendition. Thanks for today's topic!
Thanks for listening
Thank you very much for the info, It helps a lot with me building a model ship from scratch.
Thank you! I am glad it helped
Thank you, as usual!
My pleasure!
Never has being victimized been such a pleasant experience. Thank you once again for an enlightening lecture!
Thank you! I am glad you enjoyed it!
When did half modeling become a design tool? Good luck with your fieldwork. I am looking forward to any field footage you put out.
Thankyou.
You're welcome
Ah, Prof Hawker--there is a fellow who knows his peas and carrots. More than passing familiar with H.I.Chappell, too. I still loft things in those "old fashioned" ways. It's why I struggle wuth Blender and SketckUp and always return to AutoCAD (my ACAD relationship going back to 1983 & grad school)
More, please !
I'm working on it
Please continue, sir. For me, you are explaining the equivalent of a Space Shuttle in that time. As an aside, some comments on why some shapes are bad sailors and others are good ones?
👍👍👍👍👍
👍
Thank you so much for this nice explanation. I truly enjoy your videos, and they have become one of the highlights of my Sunday afternoons.
Please allow me one question - when we are mentioning "the shape of the vessel", does that include the planking? I.e. as a shipwright (or model builder) one would have to subtract the thickness of the planks to derive the outer shape of the frames?
That is a great question; I was kind of wondering that as Doctor B was talking about ship's lines. Ill be hanging on to see if Dr B can explain.
Yes, if the lines are drawn "to the outside of the planking" the frames must be lofted with deduction for the thickness of the planking. It depends upon whether the lines were drawn "to the inside" or "the outside" of the planking. The Table of Offsets or the lines drawings themselves if dimensioned, will always indicate whether they are drawn to the inside or outside of the planking.
Thank you for bringing up this topic.
Some 20 years ago I started creating CAD drawings for Chapman's Bellona frigate series, specifically the Camilla, but unfortunately lost access to AutoCAD which I was using for the task.
Do you have any suggestion for software to use? Which software is used in the Video?
At some stage, I'd like to pick up on this project again!
Not sure about the software used in the video, but there is a free ship CAD program that you can find by searching the web for "freeship plus in lazarus" (I won't post a link as youtube seems to make messages with links disappear). I'm sure it's not good enough for professional naval architects, but seems to be used by hobbyist boat designers. Hope this helps.
This is AutoCAD but unfortunately I don't know this software, so Olya does all the illustrations for me
@@kroumbatchvarov-archaeologist You might consider a video on traditional lofting in the modeling context using manual drafting instruments (board and tee-square, compass, proportional dividers, weights ("ducks") and battens, and ship's curves.) It seems many beginning modelers "go down the rabbit hole" trying to create CAD programs for CNC applications and 3D printing when, for modeling applications, at least, the traditional technology is much less expensive, much easier to learn, and quite sufficiently accurate. I'm certainly no digital draftsman and far too old to learn the new tricks, but the last time I checked, it took an exceptionally sophisticated and expensive program to draw a fair curve on a computer that could be done with a batten in minutes. If some of the content on ship modeling forums is any indications, some poor guys spend more time trying to load manually drawn plans into their CAD program data files than it would have taken them to build the model itself!
Thank you for the video. Curious what was the software you’ve used?
Thank you for watching.
This is AutoCAD
Will you do a video on masting?
I hope so, but I don't promise it in the near future. Because I need to do some research…
