"Nathanael G. Herreshoff Coconut Grove Miami, Florida Feb. 6 - 1931. {1931/02/06} Dear Francis - ... I have the model yacht planked and am now laying the deck, when I took her up after planking, and with all deck beams in it weighed 3 lbs 5 oz. and I expect hull will weigh finished 5 1/2 lbs, - the rig 1 1/2 lbs. The figured displ is 42 lbs. and I am making lead pattern to weigh 37 lbs which is 86% of displacment. It is to be Ketch rig, (a yawl with mizzen mast a little forward of w.l.) and should have the usual allowance in racing. I get tired easily so it is doubtful if it is finished before getting home. We are still having cool weather with entire absence of the trade winds. With best regards & wishes Your affect Father." [Note: The model boat Trillium at the Herreshoff Marine Museum is not a ketch, indicating that this letter either refers to another model boat or that N. G.

"Dear Sirs:
I have been much interested in reading the article in your October number entitled 'A Novel Automatic Steering Gear for Model Yachts,' as I have had quite an experience with devises for steering sailing models directly by angle of wind movement to the course desired for the model, and I consider it the best principle, when the details are properly worked out. Way back in 1875 when I was working on double-hulled sailing craft --- the details of which I had patents and I also constructed many --- I made a model [#187504es Amaryllis Model Yacht] of the contrivance about 33 inches long. This I sailed, but could not keep it on a course until I added a wind vane that controlled the rudder, and it did the trick perfectly.
Due to busy days, I did no more with the idea until a few years ago, when I took up model making just to give exercise without having to stand much over on fatigue. I built four models [#192901es, #193001es, #193002es, #193103es] to which I applied the windvane steerer, and when I tried each proved successful. I carried out the details somewhat different in each case, but all having the same principle of connecting the rudder to the wind-vane so they turn reverse directions. In one case a pin on the arm on lower end of vane shaft worked in a forked tiller turned on the rudder shaft, exactly as shown in the illustration on page 148 [a reference to a vane gear mechanism invented and described by the yacht designer Jac. M. Iversen of Stockholm, Sweden]. However, the details of the vane shaft and adjusting mechanism are quite different. The arrangement as shown in your paper is crude, as it is not designed to eliminate friction and the inertia of moving parts. In mine the wind vane is counter balanced so that careering or rolling of the model will have no effect. The entire weight of vane and gear bears on a fine pivot point, so the slightest air will swing the vane. Also, the rudder blade is of the same specific gravity as water, so it is not effected by careering and turns very easily.
I tried an elastic centering device and found it was not needed, and I also arranged a disc on the vane shaft with a circle of pin holes that a pin on the vane dropped into to hold the vane at desired angle and gave that up in favour of a friction arrangement on disc that is adjustable by screws to give sufficient friction to control the rudder, but can be pushed round to any angle in an instant without breaking anything.
I sent a drawing of this arrangement to a New York yachtsman and model enthusiast who asked for it, with the declaration that I had not patents, and gave it freely to the public. Unfortunately, the device was not carried out correctly and had considerable friction and, therefore, failed.
The principle certainly is not patentable, but of course some special details may be.
Yours Truly,
Nathanael G. Herreshoff." (Source: Herreshoff, Nathanael G. [Letter to the Editor.] The Model Yachtsman, England, December 1932. Quoted in: Boebert, Earl. "Nathanael Herreshoff's Vane Gears." The Model Yacht. Newsletter of the U.S. Vintage Model Yacht Group. Fall 1999, p. 3-7.)

"Dear Junius,
... I have asked the H.M.Co. several times to try out a loose footed sail with double curved boom on one of their small crafts, but could not get them interestes, and I am glad to know you have taken it in hand. Thus far my experience it only with model yachts [#192901es Robie, #193001es Trillium and #193103es Sprite], but I believe it can be used successfully on small sailing craft and that it can be arranged to be equally conveniant is use as ordinary rigs, and for equal sail area be more efficient.
I have found no difficulty in applying the double curved boom on model yachts, excepting of course more work in making it. I am inclosing the aft end of one of the booms that I shortened which will show how it is made. Each side bar is glued up of three pieces. The outside ones of good clear spruce. I first shape a mould of a little more curcature than the finished side bar and a little longer, so the first and second layers can be tacked at the ends to place before the third piece is laid in and clamped to hold the glued pieces while drying paper must be laid first. I get the pieces out quite a little over double width, to allow for sawing in two and planing the edges after gling, and so get both sides, at one glueing.
The forward end I have made in two ways. One, the saddle to take bearing in mast, of thick and strong metal bolted to the side bars with a facing of leather to mast, and the other, as you have it with a wood block to hold the side bars, that is to be forward of the mast. [Sketch.]
In this case I make the saddle of very thin brass held bu one bolt each and that goes thru the side bars. [Sketch.] The saddle parts are bolts so it always has a true bearing on mast and needs no leather.
I hope I have not tired you in describing how I do these things, but I have had much pleasure in designing and making them, as probably you have in your work.

"February 10, 1931 {1931/02/10} Dear Father: ... I was interested to hear of your progress on the model yacht. I am also very interested that you are going to rig her as a ketch or yawl, and I am quite sure this is the most satisfactory rig for a model yacht and think she will sail much steadier than anything else. I would not try to overwork if I were you for after all if you get pleasure from working there is no need of hurrying up and finishing it. ..." (Source: Mystic Seaport Museum, L.

Also the sharp sterns stear noticeably better when driven in hard before the wind. ..." (Source: Mystic Seaport Museum, L. Francis Herreshoff Collection, Box 17, Folder 7: Letter from L. F.

I am inclosing sketch of the 'vane steering' about like one I sent Tobey last spring. I think you will understand it and you could easily make one with the tools you have.
The lead balancing weight should be around 2/3 w[ei]g[h]t of vane tail and when both are mounted on the bar move the bar along in hub ill a perfect balance is obtained, then tighten set screw.
It is well to make rudder blade so it will just sink and of course have the rudder and all connections so they are perfectly free. I would cut out opening in side of column so the steering arm will allow rudder to swing about 15deg each way from [center].
Ashton, the [HMCo's] painter, is just [p. 2] painting # 3 model [#193001es TRILLIUM], and then the rigging up So I think she will be completed in about a week.
All well here.

"[Item Transcription:] [Handwritten (in ink) letter on 'N. G. Herreshoff, Bristol, R.I.' stationery:] Dear Francis Lee,
I started to make a sketch for you of the 50in model yacht [#193204es], but after thinking it over a little decided it would be more interesting to make a model which perhaps w[ou]ld be better for you to look at than a sketch, as my eyes are not good at drawing any longer and I prefer to use tools. I did attempt to make a few calculations from pantograph sections which are on another sheet inclosed.
Perhaps the design represents a rather large body for the sail area but with the model lines carried out to include rudder, the wetted surface is not larger and with nearly 21lbs lead you could afford to set the sail rather high up and make it more effective in light breezes. However, I didnot [p. 2] make this for you to build from but only as a guide in carrying out your own design, which you should by all means do. Your head is overflowing with ideas of what a toy boat should be and you should go ahead and develop them.
When trying my 3rd toyboat 'TRILLIUM' [#193001es], I was very much impressed with the ease and dryness of decks when she went thru the seas and in this model I gave it the same type of bow.
It may not be good for a large vessel, as she would pound and throw spray probably, but it is certainly good for little ones.
Your affect[ionate] Uncle Nat
P.S. The model is to be sent by parcel post." (Source: Herreshoff, N.G. Letter to Herreshoff, Francis Lee. Halsey C. Herreshoff Collection at the Herreshoff Marine Museum Item MRDE02_02860. Folder [no #]. 1932-11-25.)

"[Item Transcription:] [Final, slightly altered, version of handwritten letter on N. G. Herreshoff stationery:] I am pleased and interested to have your letter of 15th. I have not heard of the little boats [#1148s Development Class for Junius Morgan and #1149s PIG IN A BAG for George Nichols] built for you & George since they were delivered which was at the time there was great interest in the Cup yachts. Have you found your boat an interesting one to play with? George has never written of his. A year ago last summer the H.M.Co. built a boat [#1203s CYGNET] for Paul Hammond, from my designs that was a little shorter and wider than yours, and he wrote he had much fun with it and really enjoyed it more than any of his various boats.
Your proposed change of rig is interesting indeed and I will be very pleased to know how it works out, and hope George will have his boat out with standard rig to try yours and really discover if there is an advantage of the overlapping rig with sails of equal area. Also to decide which is the most conveniant rig to set up quickly and use. You know my contention had been right along, the only advantage of overlapping sails comes from a false ruling. That is spar measurement instead of sail area. Of course, spar measurement is more definate, but I believe a system of measuring sails that will be satisfactory is quite possible, and although more troublesome to the measurer would be very much less than the owners trouble and expense for the light sails and extra crew required to handle them.
I have asked the H.M.Co. several times to try out a loose footed sail with split and curved boom on one of their small craft, but could not get them interested, and I am glad to know you have taken it in hand. Thus far my experience is only with model yachts [#192901es ROBIE, #193001es TRILLIUM and #193103es SPRITE], but I believe it can be used successfully on small sailing craft and that it can be arranged to be equally conveniant as ordinary rigs, and for equal sail area be more efficient.
I have found no difficulty in applying the split & curved boom on model yachts, excepting of course more work in making it. I am inclosing the aft end of one of the booms that I shortened which will show how it is made. Each side bar is glued up of three pieces. The outside ones of good clear spruce and center one of cedar or light white pine. I first shape a mould of a little more curvature than the finished side bar and a little longer & over double width. First lay paper then the first strip with glie spred[sic] on face and tack at each end. The others in order, and then use plenty of clamps till dry. The stock is got out enough over double width, to allow for sawing and planing and thus get both bars at one glueing.
The forward end I have made in two ways. The first with strong metal end that acts as saddle against mast and bolted to side bars. It should have a leather facing. The other, as you have it with a wood block to hold side bars that is forward of mast. In this case I make the saddle of thin brass, held by one bolt each end that goes thru the side bars. The saddle pivots on bolts so it always has a true bearing on mast and needs no leather. I hope I have not tired you in describing how I do these things, but I have had much pleasure in designing and making them, as probably you have in your leisure hours." (Source: Herreshoff, N.G.

"[Item Transcription:] [Penciled letter draft on back of Yenching University letter, undated but December 17, 1932 as per NGH note on Junius Morgan letter dated December 15, 1932:] I am pleased and interested to have your kind letter of 15th. I have not heard of the little boats [#1148s Development Class for Junius Morgan and #1149s PIG IN A BAG for George Nichols] built for you & George since they were delivered which was at the time there was great interest in the Cup yachts.
Have you found your boat an interesting one to play with? George has never written of his. A year ago last summer the H.M.Co. built a boat [#1203s CYGNET] for Paul Hammond, from my designs, that was a little shorter and wider than yours and he wrote he had much fun with it and really enjoyed it more than any of his various boats.
Your proposed change of rig is interesting indeed and I will be very pleased to know how it works out, and hope George will have his boat out with standard rig to try yours and really discover if there is an advantage of the overlapping rig with sails of equal area. Also to decide which is the most conveniant rig to set up quickly and use. You know my contention had been right along, the only advantage of overlapping sails (Genoa jibs & c) comes from using more sail area than is paid for. The trouble comes from a false ruling. Spar measurement instead of sail area.
I have asked the H.M.Co. several times to try out a loose footed sail with double curved boom on one of their small crafts, but could not get them interested, and I am glad to know you have taken it in hand. Thus far my experience is only with model yachts [#192901es ROBIE, #193001es TRILLIUM and #193103es SPRITE], but I believe it can be used successfully on small sailing craft and that it can be arranged to be equally conveniant in use as ordinary rigs, and for equal sail area be more efficient.
I have found no difficulty in applying the double curved boom on model yachts, excepting of course more work in making it. I am inclosing the aft end of one of the booms that I shortened which will show how it is made. Each side bar is glued up of three pieces. The outside ones of good clear spruce. I first shape a mould of a little more curvature than the finished side bar and a little longer, so the first and second layers can be tacked at the ends to place before the third piece is laid in and clamped to hold the glued pieces while drying paper must be laid first. I get the pieces out quite a little over double width, to allow for sawing in two and planing the edges after glueing, and so get both sides, at one glueing.
The forward end I have made in two ways. One, the saddle to take bearing in mast, of thick and strong metal bolted to the side bars with a facing of leather to mast, and the other, as you have it with a wood block to hold the side bars, that is to be forward of the mast. [Sketch.]
In this case I make the saddle of very thin brass held by one bolt each and that goes thru the side bars. [Sketch.] The saddle parts are bolts so it always has a true bearing on mast and needs no leather.
I hope I have not tired you in describing how I do these things, but I have had much pleasure in designing and making them, as probably you have in your work." (Source: Herreshoff, N.G.

"[Item Transcription:] [Handwritten (in ink) letter with 'Frank G. Smith, 73 Woodside Ave., Waterbury, Conn.' letterhead marked in pencil by NGH 'Ans. Mch. 11 and inclosed 2 photos of model yachts (probably #192901es ROBIE or #193001es TRILLIUM):] I cannot resist enclosing this personal letter along with the answer to your inquiry [to the American Brass Company].
Although I was born in Torrington, Ct. I have been interested in yachts since I was about 5 years old. I have the first 'model' of a schooner about 5in long with match sticks for masts which made when I was 5.
When the DEFENDER [#452s] won the America's Cup I was so enthusiastic about yachts as youngsters are about airplane models today. I was almost 8 then, and I knew you designed her as well as the others which followed. i am 49 now and a metallurgist by chance for the past 20 years. Would have preferred to be a naval architect if I could have left high school to go to college to follow my natural interests, but I had to [p. 2] go to work for 4 years and so worked in the American Brass Co. mills at Torrington.
After leaving High School I built 2 canoes and a sailing dory all of which I designed. Nothing has been done about boats since except to read about them and admire them, until a few years ago I built 2 models. 25in w.l. There are photos enclosed. The gaff rigged model was designed by C.D. Mower. The staysail rig I designed myself (an 'R' class). When finished it floated as I had designed it. It is 39 1/2in o.a., 25in w.l., Disp[lacement] 6 1/4lbs, lead 4lbs 2oz, s.a. about 600sq in. The half model of a schooner was made for one of our Vice Presidents.
I think nothing is prettier or perhaps grander than a fine sailing yacht. Always your name has been something to think about. Today I don't know much about yachts but I have had about years with the A.B.Co. Pipes and tubes [p. 3] [verso not imaged]. [Accompanied by three photos.]" (Source: Smith, Frank G. Letter to N.G.
