"Coconut Grove, Fla. N. G. Herreshoff Bristol, R. I. Jany 19 - 1929. {1929/01/19} Dear Francis - About the Development boats - I have been amusing myself and have worked up two designs, and the models of hulls will be sent you by parcels port, and rather crude pencil sketches of rigs I am inclosing with this, - all of which please accept, as representing the ideas of an old man who has done a lot of sailing in boats of this class. Model A with perhaps the sheer raised forward - like B - w'ld probably make the most satisfactory boat for general use, but I am inclined to think B w'ld be fastest in racing, and particularly in light winds. B has sections almost like Coquina [#404s], but a little rounder forward, - so waterline is not so hollow. Coquina is about 16 1/2' over all and 15' w.l. - so is about 2 1/2' shorter than these models. I have not the weights of Coquina with me but from memory - hull, bare, was about 260 lbs. - metal c.l. 35. - rudder & oars, 15. = 310 lbs. small rig (120 square') Sand bags - 175 Self - 160 Total - 690. My estimate for boats from these models, if cedar planked and reasonably light wood decks & wood c.b. [centerboard] are [Chart showing lbs of Hull complete, Rig, Crew-(2), Ballast] [p2] The w.l. drawn on models roughly indicate displacements, including keel & rudder of 730 lbs for A and 770 lbs for B. Roughly calculated the wetted surfaces are, - for [Chart showing sqft of Hull -, Keel & rudder, 1/2 centreboard, sail area, Wetted surface] The inclined waterline on models is at 15o The sail plan for A is what I consider a good useful one and not difficult or expensive to make I would make the masts round and hollow, and the yards hollow and round section unless it thought desirable to give it form as shown on drawing for B. You will notice I have placed the masts well apart, so the mizzen will get clear wind as possible, and also the clues very high up, so to get equal effectiveness at upper & lower part of luff of sails. The sprit-boom is double with a traveler for seperating the forward end, which thrusts against rollers in jaws, and intended to have the boom slide to leaward when tacking, and give the sail a clear draft. I believe this arrangement will work well. You will notice the reef does not include the clue, and makes reefing simpler. The Mizzen to have two sheets and the one to weather quarter to be the effective one, and the line end of to run forward along side to be belayed about abrest the centre-board. The main sheet to have standing end on the mizzen mast as high up as is conveniant [p3] to reach - or that sets the sail properly. (It is supposed the mizzen boom jaw will be raised to hight to give proper set to mizzen.) When the mainsail is reefed, the the main boom jaw will have to be raised some higher along luff of sail, and the standing end of main sheet shifted to floor just aft of c.l. casing. I have found it much better and safer to abandon using a tiller, and have instead, ropes that lead to proper position of helmsman, - when near amidships and hiking out to windward. It riquires 6 good easy running blocks - 2 with beckets - with good dia. of sheaves, and ample in size for 1/4" or 9/32" dia. rope. Two leading blocks should be on the thwart way out to the side, so the rope will lead across forward of mizzen mast, and have a handle at middle of it with a take-up arrangement to adjust tension of ropes. I used cotton rope that had been run thru melted paraffince with surplus well wiped off. With a rig almost like A that I had on 'Lantana' [#192101es] - the 14'9" boat I bought from you, and rigged up to use during our southern cruises, - I found it very conveniant indeed, and the sails very efficint, so that she was a very good sailer. In her I carried some stationary ballast, - about 200 lbs of sand in 2 meal bags, placed each side of centreboard near forward end, and 2 small sand bags carried aft when alone and forward when with 1 or 2 persons - who were aft the mizzen mast, my steering position being forward of mizzen mast always, The Racing Rig I have been trying to develope has some new features, beside copying yours of very [p4] short masts and long curved yards, but keeping lengths so they can be stowed on board. You will see I have attempted to stream-line the combined sections of mast and yard in parts that they lap, making lower part of mast circular and stream-lined the sections of yard, above mast. Masts have extra length at top to be able to set sails very high up in light breezes, and also arranged to set lower than normal position in fresh winds. I intended to have masts set thru antifriction rings set in partners, and a pintle at lower end - so that masts revolve with yards I see no reason why the stream-lined yard with luff of sail pulled thru bulbed groove made in aft side of yard should not be practical. It is intended to have lower end of luffrope above the tack cringle and enter the sail always at top of yard. There is no need of having much strain on luff near lower part. With the exception of setting sails high up in light airs I don't think all the extra cost of this rig is worthwhile - over what I have shown on A I tried to figure out some practical plan to have curved centre-boards which without doubt w'ld increase speed to windward, but gave it up. I think 2 centre-boards (a builge board) and a wide slotted c.l. casing at forward end should be ruled against, and possibly revolving and stream lined masts. You will notice I have no stays or shrouds, as they complicate setting and taking down masts so much. I hope you will find a little in this long letter that is interesting Your affect. father Nathl G. Herreshoff." (Source: Mystic Seaport Museum, L.

"Dear Junius,
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....

"N. G. HERRESHOFF 6 WALLEY STREET BRISTOL, RHODE ISLAND Dec, 15. 1935 {1935/12/15} Dear Francis, ... Sidney recently tried out a Development Class boat that I designed for Com. George Nichols some years ago, - with an up to date rig having a revolving mast, that Mr. Nichols has sent to Coconut Grove, and hopes to have (?) interesting sailing against Wirth Monroe (and others) during the holidays. I think we all were impressed at the ease this craft got away from 'Velita' [#193301es]. Which carries out your contention for more length, when you are not charged for it in racing. ...

"The other rule is the Development Rule gotten up by William Atkin in about 1927 when he was editor of the fine little magazine Fore 'an Aft. Unfortunately this rule came out when there was little interest in the smaller and lighter boats and before the present interest in dinghy sailing was started. Also unfortunately this class was nicknamed the Suicide Class simply because some of the first boats had reckless names. The idea of the class was to encourage experimentation and for that reason the rules were very simple but practical, and amounted to limiting the actual sail area to 125 square feet; the planking must be 5/16 inch or more thick, and the beam over 3 feet 6 inches but not over 5 feet 6 inches. The centerboard must house entirely in the hull so the boats can be hauled out on a float. Otherwise the sky is the limit. These little boats are the most fun to sail of any that I have ever tried, not barring sailing canoes ... [The illustrated boat] was designed by my father when he was about eighty-five years old for Commodore George Nichols.
It is my opinion that this class produces a boat vastly superior to the International 14 footers and probably quite a little faster for their actual sail area, for the International 14's actual sail area seems to be between 150 and 160 square feet but their hulls are much too short for these areas in a high narrow sail. The 14's are very uncomfortable and dangerous, as they are not allowed to be decked in and altogether are a rather stupid class since there are too many restrictions and they are expensive to build. The Development class on the other hand allows almost unlimited experimentation, and in a boat of this size experimenting, particularly with different rigs, is lots of fun for the expense is little. This class is about the other extreme from the one-design classes and we certainly should do something with it, for it gives by far the most fun for the money of any class that I know of." (Source: Herreshoff, L. Francis. The Common Sense of Yacht Design. Vol. II. New York, 1948, p. 65.)

"He was much interested in the Development Class of small sailboats, the rule for which was gotten up by Bill Atkin, and he designed four or five for this class. Some of these boats had different rigs of the same area, and this made them unusually interesting to race, for the rigs could be changed in a few minutes. A few of these little boats are still in existence, but they were a little delicate and required careful handling although when in the water were fast and lively, and, if properly handled, were remarkably good sea boats. It is interesting that Captain Nat at his advanced age took such interest in these light boats, and he wrote several enthusiastic letters to me about them when he was eighty-five or so."

"23 Wall Street.
New York
December 15, 1932.
Dear Mr. Nat:
I thought you might be interested to hear what I have been doing on the rigging of my little sailboat that you designed for me three years ago. I have concluded to try using the standard ketch rig as a jib and mainsail and I found that by stepping the mast just at the forward end of the center-board case, where a step is provided, I could get a mainsail and overlapping jib using the two sails 'as is'. I enclose a sketch, not to scale, of the sail plan which will, theoretically at least, balance fairly well. I am also making a new sprit for the mainsail which will, I think, make it set better, as there will be nothing to interfere with the sail on either tack. While the mast stands all right without support with one sail on it I thought it probably needed a little help when carrying both sails, so have arranged the necessary tangs for shrouds on it. When the rig is finished, and I can put the boat in the water, I will let you know how it works out. It may not work, but at least there will have been the fun of playing with it. ...
Very sincerely yours, [Junius S. Morgan]. [Sketch included.]" (Source: Morgan, Junius S. [Letter to N. G. Herreshoff.] Herreshoff Marine Museum Correspondence, Folder 50 (new), 181 (old). Access courtesy of Halsey C. Herreshoff. December 15, 1932.)

"... Development Class, where a substantial degree of freedom was granted the designer. The idea in this case was to have light craft with a specified small sail area (125 square feet), and a minimum of restriction. It was a foolish but pious hope that a rule as loose as the one used would not be exploited to near absurdity. The Development Class unfairly received the nickname, 'Suicide Class.' The boats were brightly taxing to handle but not vicious or dangerous. Some of the original batch of Development Class boats sailed at Coconut Grove. Others were on the North Shore of Long Island. Capt. Nat was represented in both locations with an unusual design which has been characterized as resembling a light 'whale boat with a square stern and wishbone booms for main and jib.' Two of these were near twins, built in 1930, for future Commodores of the NYYC, Junius S. Morgan and his brother-in-law George Nichols. One has been preserved, the Nichols boat, at the Mystic Seaport Museum; a similar third at the Herreshoff Marine Museum. [Ed. Note: CYGNET, the Development Class boat at the HMM, (The General Utility Class - hull #1203) was built and always owned by Paul Hammond until donated to the HMM.]" (Source: Streeter, John W., editorial note.

"While their J-class America's Cup contender Weetamoe [#1147s] was under construction, brothers-in-law Junius Morgan and George Nichols had a matched pair [#1148s and #1149s] of NGH-designed, so-called Development-class boats built. NGH had been much taken with the newly formulated Development-Class Rule and carried on a lengthy correspondence with his son L. Francis about its potential in creating practical small sailing boats that could compete against one another and demonstrate the speed-giving qualities of various hulls and rigs.
The boat ... and her sister could be rigged with one, two, or three masts, and, although larger than the usual rowing craft, they were fitted with oarlocks for rowing when there was no wind.
One boat was trimmed in teak, the other in butternut; both had lifting eyes for hoisting on davits. This was the dawn of the Herreshoff Mfg. Co. wishboom era, and the sails are so fitted. One of the middle thwarts (designated as a slip-thwart on the Herreshoff Mfg. Co. construction drawing) can be removed to make space for sleeping on the floorboards. Gear can be kept dry under the afterdeck storage compartment, and steering is by tackle rather than tiller. ...
These intriguing boats must have been a relaxing alternative to the intensity of the J-boat racing that was soon to follow." (Source: Bray, Maynard and Carlton Pinheiro. Herreshoff of Bristol. Brooklin, Maine, 1989, p. 169.)

"[Item Transcription:] Thank you for your letters of 23rd & 24th [September 1929] and the Huntington Y.C. Development Class Rules, also photo of the Atkin designed boat. The rules or restrictions do not have much good reasoning and i believe ours are much more to the point to develop a good class.
One thing I omitted was that boats be provided with suitable eyes for lifting out and hanging from davits.
There were two of Atkins designed boat[s] at Coconut Grove, Fl. last spring and I had the opportunity of seeing and also sailing against one of them. As they came they were very poorly rigged but we fitted into one of them the rig of a 14ft class [Biscayne Bay 14-footer] I designed, having 121 sqft. Jib & mainsail. With this she sailed very well. In a breeze faster than my 18 1/2ft w.l. outside ballasted boat [#982s WATER LILY ex-LIMITED] in broad reaching & running, but not at all in it when turning to windward.
I am pleased that you will try out the three masted rig in the two boats [#1148s Development Class for Junius Morgan and #1149s PIG IN A BAG], but I am wondering if it would not be interesting to you to also try out the jib & mainsail rig also. I would propose that you have both boats fitted with, what I may call, the standard rig. --- The Sharpie rig I first proposed then as extras. 1 - three masted rig and 1 jib & mainsail rig. --- Either rig will be fitted to either boat.
They are ready to begin planking the 1st boat [#1148s Development Class for Junius Morgan] this afternoon.
With kind regards ..." (Source: Herreshoff, N.G. Letter to Morgan, Junius S. Herreshoff Marine Museum Collection Acc. 98.45. Correspondence, Folder 32, formerly 181. 1929-09-25.)

In case you would paint her Gray the way your other boats are, we would suggest that the inside should be painted in some lighter shade of gray so that all the Teak work should be kept bright.
I thought first that the boat should be varnished and not painted, but Mr. Nat seems to think that a painted boat is much easier to keep in good shape,

"[Item Transcription:] [Typewritten letter marked 'Copy' on 'Herreshoff Manufacturing Company, Bristol, Rhode Island' stationery:] The daily routine keeps me frightfully busy and letter writing goes slowly.
We took some time ago the first boat [#1148s Development Class for Junius Morgan] of the development class and put her overboard. We put five sandbags into her and careened her according to your instructions.
She did not get her covering board into water, the water stopping just below.
We had the sails ready at the beginning of this week but I had to go to New York and consequently the boat was not tried out.
Yesterday morning [December 6, 1929], it was a little warmer than the days before and we put the boat over in hopes that a nice little Southwester should come up. It was however calm all day and the best we could do was to see what the three different rigs looked like.
If it was my boat and I had a free day, I cannot see how the day could be spent better than playing with the three masted rig. A man could have just a glorious time trimming sheets on this rig. The only objection I have to this rig is that the mainsheet bridle is right in front of you and you must crawl under it to get forward in the boat. The Foresail sheet must also be made to go over a lead forward of the foremast so that the sail will trim right.
All the spars should be furnished with small cleats for the halyards. The tiller rope leads on the thwart must be lifted up, the way they are now the tiller rope chafes on the thwart bracket.
The double rig is very nice and probably the fastest. Nothing to change except for cleats on the spars and, I think, a cleat for the mizzen sheet. The arrangement with a pin under the thwart does not seem to work very well when there is very light air. The main mast does not seem to be any too strong.
The jib and mainsail rig. There is something wrong with this rig. The mast is not stiff enough and should be considerably increased at the head. Even yesterday, the pressure of the halyard gave it a bad bend.
I doubt also if the Job ever can be held properly because as soon as you pull on the mainsheet, the mast goes forward.
I don't see but some kind of backstay arrangement must be furnished.
The small hooks with the bronze link will probably cause trouble. You must set them up with a hammer if you want them to stay in place when the sail is shaking.
The boat is very stiff and able indeed. My 174 pounds hardly moved her at all when I walked by the masts.
Some day when it is warm and a stiff breeze blowing, I will take her out again and tell you more about her.
Sydney[sic, i.e. Sidney] looks very well.
On Monday, I will write you about our doings in the shop. With my best regards to Mrs. Herreshoff and Commodore Munroe,
I am
Yours very truly, Herreshoff Manufacturing Company. [With handwritten P.S.:] We will naturally make no changes before having your instructions to do so." (Source: Nystrom, Charles G.

He sent me same, and they were very interesting to me. I have been in hopes to hear from him of a trial in a little breeze, but there is nothing.
The cold weather of winter is not a good time to tune up little boats --- such as adjusting the sprit booms to proper height on mast --- getting the proper tention[sic] on prodder lanyards --- adjusting tiller ropes so to work freely and still not too slack, are a few things cold fingers rebel at.

"[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.

Spar measurement instead of sail area.

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:] [Typewritten unsigned carbon copy marked 'File Copy':] A few days ago Charles Nystrom was here and left with me the specifications for the 14 foot Dinghy Class, which would I think produce a highly satisfactory boat. There is perhaps some question whether it would be possible to start a 14 foot class here in view of the existence of the international class of the same size abroad, which seems to be highly scientific in design and construction and has long since departed from the utility dinghy idea
As far as I personally am concerned, I like your rules very much, but am not sure what what I can do to help further the development of a class under them. If you would care to have me do so, there are one or two people with whom I can discuss the question and see what steps, if any, could be taken towards getting a class started; but before discussing it with anyone else I should like to hear from you what you would think of the idea of putting some limit of cost on the boats and what you think that limit should be. Using one design hulls and allowing experimentation with rig might help this phase of the question, but on the other hand would destroy the possibility of development in hull design and I for one should not favor the one design idea.
I am delighted to hear from Charles that you are keeping well this winter. Best regards to you.
Very sincerely yours, ...

"[Item Transcription:] [Handwritten signed letter on 'N.G. Herreshoff, Bristol, R.I.' stationery:] I am pleased to have your letter and interesting photo of the Development boat [#1148s], and am glad you have tried the double boom and approve of it. The next thing is to demonstrate it is perfectly practical and there is no cause to rule it out or in fact any sprit boom.
My impression is the jib that was cut for a sail to be attached to mast and gunteryard is not right when attached to a stay and so used has too much bag and you are not getting the full benefit of the rig.
I agree with you that it would be more practical to do away with shrouds and have stronger masts in this type of boat in which the rig is removed when not wanted for use.
I have been interested recently in formulating restriction rules for small sailing craft that can be kept out of water and housed when not in use, which I think would interest you.
When I get some type-copies that Chas. Nystrom has offered to make for me I will send you one and hope you will look it over and point out flaws or faults in it.
[p. 2] When you have a trial with your boat and rig with George [Nichols]'s boat [#1149s Pig-in-a-Bag] having the A rig, I will be much interested to know how it comes out.
With best regards,
Sincerely yours ... [Dated May 10, 1933 by NGH, which would have been the date of the letter he responded to --- on which NGH noted that he responded on May 12, 1933.]" (Source: Herreshoff, N.G.

"[Item Transcription:] [Original letter:] I have had a chance to look over your suggested rules for small sailing boats and am much interested in them.
I think as to your Class 'A' Boat the sail area of 168 feet may be a little large. My boat [#1148s] seems very satisfactory at 121, which is probably now slightly larger owing to the stretch of the sails. However, this is a matter about which you would know much more than I.
The other point on which I would like to comment is the question of solid spars. It seems to me that for a boat so arranged that the rigging is easily taken down the weight of a solid spar would be a detriment. I don't believe there would be much advantage in the cost, owing to the fact that satisfactory solid grown spars are hard to find and that a built up solid spar would is probably nearly expensive as the hollow one.
Apart from those two comments, however, it seems to me that the rule is a most satisfactory one and would produce an excellent type of boat. I have turned it over to a friend of mine who might be interested in starting a class next season at one of the clubs. I hope they will develop something out of it, as I am sure a most satisfactory class of boat could be built under it; incl NGH draft reply: pleased to get your of 13 with criticisms of the proposed class rules. I am sure it was very good in you in writing me and shows your genuine interest, for your must have been quite distracted by the deplorable investigations at Washington which to my thinking is envy of certain ones who don't gain the confidence in the financial world more than anything else. The very unexpected death of my close friend Altie Morgan has been a great shock to me. I think he was the last of a group of those yachtsmen who took such active part in the defence of the America's Cup from '90 to '14 and of which I saw much off.
Referring to your kind letter. The design for your boat was made to conform to a rule having 125 sqft sail limit, and was consequently narrower and lighter than she would have been, if sail limit was allowed. But I do consider the area (168sqft) large and [it] is really a racing rig. The no 2 rig specified for each class is really a more normal siye. You will notice there is no upper restriction to beam and it is quite probable a Class A boat woll be near 6 ft beam.
About spars, hollow or solid. I certainly believe boats of the type intended would be more satisfactory with hollow masts, at least, and I would much prefer one that way. For amateur builders without the proper machine tools, I know it would be a difficult job to make a good hollow spar, but if he is supplied with such fine machines as the Delta Co are now supplying it would help out hollow spar making a lot, and if you and a few others think hollow spars (or perhaps hollow mast only) should be allowed I would be pleased indeed to have the ruling changed."

"[Item Transcription:] [Handwritten signed letter on 'N.G. Herreshoff, Bristol, R.I.' stationery:] I was pleased to get yours of 13 [June 1933] with criticism of the proposed class rules. I am sure it was very good in writing me and shows your genuine interest, for you must have been quite distracted by the deplorable investigators at Washington, which to my thinking is envy of certain ones who would like, but cannot get the confidence of the financial world.
The death of my close friend Altie [E.D.] Morgan has been a great shock to me. I think he was the last of a group of yachtsmen who took such active part in the defence of the America's Cup from 1890 to 1910 and of which I saw much of.
Referring to your kind letter, the design for your boat [#1148s Development Boat for Junius Morgan] was made to conform to a rule having 125 sqft sail limit and was consequently narrower and lighter than she would have been had not the sail area been limited so small, but I do consider 168sqft large for the hull restrictions and is a racing rig, the no2 rig of 144sqft is nearer right for pleasure sailing. You will notice there is no upper restriction to beam and an A class boat would probably have a beam approaching 6ft.
About spars, hollow or solid, I certainly [p. 2] believe boats of this type would be better with hollow masts at least, and I would much prefer one that way. For amateur builders without machine tools and many clamps I know it would be a difficult job to make good hollow spars. The fine machine tools now offered by the Delta Co. at very moderate prices are a boon to the amateur and with clamps he should be able to construct hollow spars and if you and a few others think hollow spars (or perhaps hollow masts only) should be allowed, I would be pleased indeed to have the ruling changed.

"[Item Transcription:] [Typewritten, signed letter on 'Herreshoff Manufacturing Company, Bristol, Rhode Island' stationery:] I showed your new rig [for #1148s Development Boat] to Mr. Nat and he thinks highly of it. He naturally mentioned his pet Gunther rig, but I told him that was out. However, we would like to make some suggestions.
First, we find that the spar is seriously weakened where it ought to be strongest, that is in way of the sprit boom. You have showed a round section in this place to make it possible for the boom to revolve around the spar. We think it would be better to make a revolving spar the same as we make for our dinghies and consequently be able to carry a boom which does not have to revolve, but can easily be detached from the mast when not used. This would make it possible to carry the same section of the mast straight.
We feel that by attaching the forecastle stay and the shrouds on the forward side of the mast all on one fitting, the spar would take its natural position no matter which way the wind is blowing.
We also think that it would be handier to have some sliphooks with leverage attached to the lower end of the shrouds and the forestay. These slip-hooks should be fastened to the rig with an adjustable lanyard to take up whatever play is necessary.
The mainsheet would preferably be attached to a bridle spanning the boat so that you might be able to trim the sail as flat as you liked without having to resort to a traveler.
[p. 2] When I come to New York we can talk these things over. In the meantime Mr. Nat is very busy figuring out how light he dares to make the spar. We have some beautiful spruce on hand which can be used for this work.

"[Item Transcription:] [Handwritten (in ink) final version of letter:] Charles Nystrom has handed me a drawing of a new rig for your Development Class Boat [#1148s] that you have designed, with the work you, to effect, that I look it over and let you know what I think of it.
After questioning Charles how you kept your boat and prepared it for using, I understand it is hoisted out under shedded over davits, and rig removed to a boat house nearby by a man who takes care of the boat from time you leave her till again afloat and rigged for you to use.
I think you have designed a very good sail plan, and about as good as can be, provided the length of base of foretriangle is to be considered in sail measurement. If it is not, which I think is the case, it is a question in my mind, if the rig would not be more efficient if the jib (of 38 sqft) was moved forward to keep it well clear of mainsail. I may be wrong, in my belief, but I do know that along in the [18]90s the 'Raceabout Class' of Buzzards Bay 21 footers [p. 2] with restricted actual sail area of 600 sqft after a few years of intensive racing they removed the jibstay well forward on the forward overhang, so the jib was well clean of mast, and with improved results.
Differing from my suggestions of last spring for Utility Classes of Dinghies, in which I proposed solid spars without standing rigging (this of course you understay[sic, i.e. understand?] was to cheapen cost, and certainly not what I would do for my own use) you want to have the lightest rig consistent with strength and donot care to stow it on board or have the extra trouble of fixing stays:- may I make a few suggestions toward the details in carrying out your sailplan?
First I question the policy of cutting away the sailtrack wood on aft side of mast to allow space for the double spritboom bearing. Since the 'meat' to make the sailtrack adds very much to strength of mast just where it should be strongest, I am afraid of it.
Perhaps you will be interested to know how I got over this difficulty two years ago when making a model yacht [#193103es SPRITE], in which I attempted to carry out a refined jib and mainsail rig [p 3] that would be proper for a small yacht having restricted actual sail area.
This model yacht I was making for a grandson carrying my name and has been boxed and put away to be given him after he is old enough to appreciate and to care for such things, probably in 10 years. In this,the mast is full length and section about like this [sketch of tear-drop mast section with integrated luff grove] and it is hung so the whole mast swings to direction of pull of sail. This is accomplished by stepping the mast on a metal pivot point, and all the stays are to a special metal fitting at forward side of mast connected thru a hinge joint that that lines with the heel[?] pivot, and so the mast takes the end thrust. Mast is held by woodscrews at a thickened place of mast. The whole fitting should not weigh twice as much as the tangs you describe to hold rigging, and possibly only 50% more. You will note by mast swinging by pull of sail, it is stream-lined to direction of wind, which a fixed mast is not excepting at anchor, --- also the mast can be made a little smaller in transverse measurement. Now, if jibstay is placed so leach of jib swings well clear of mast, the double sprit-boom can extend well forward of, and surround mast. And its thrust not taken by mast, but by a spar having its lower end on forward side of mast opposite tack of sail, and upper end about [p. 4] half way up to rigging attachment. To be a turnbuckle near lower end of spar to adjust for varying conditions of weather. Or it can be, as was in the case of a 11 1/2 ft dinghy [#1231s HUMDINK] my son Sidney rigged, with a tackle leading inboard so the crew could adjust thrust on sail any time.
I think you will see advantages in such a rig, but if you still prefer to have the jib stay placed so jib overlaps mast, I would advise running out the sail groove in mast above position of boom, padding out mast to circular form where saddle of boom bears [sketch] and have the sail cut so part below boom is just clear of mast and to be held by a short piece of laceline thru grommets in sail. Then a clue outhaul to be arranged with hauling end along outside or bottom of one side of boom, and finally run to convenient place.
I would have slip links at lower end of shrouds, runners & jib stay, without any lanyards, but arrange step of mast to be raised for adjusting the stays. I have used this plan of adjustment on my own boats for 20 years.
I am wondering if you saw an effusion of mine I sent George on Yacht Measurement? I sincerely believe it would be of great benefit to Yachting and Clubs generally if they changed to length measurement with penalties for undesirable features, as I have proposed. Also separating entirely in racing, Cruising yachts from Racing yachts.

"[Item Transcription:] [Typewritten unsigned carbon copy of a letter:] Many thanks for your letter of October 6th [1933], and your interesting and helpful comments about the sail plan [for #1148s Development Class Boat for Junius Morgan]. Since receiving your letter I have had a chance to talk to Charles Nystrom and he can give you more details than I can in a letter about our discussion. It is most kind of you to have taken so much trouble about this small matter.
I did see your proposed rules of yacht measurement, which you sent to George [Nichols], and was much interested in them. Whether it would be possible to get them adopted under present day conditions is a matter about which I should have some doubts, but certainly the principles which you lay down in them impressed me most favorably insofar as my unscientific mind could visualize the probable results. I have not had much chance to talk with George about them as he has, as you doubtless know, gone abroad to attend a yacht conference in London. I shall, however, have another chance to see them when he gets back and shall look forward to studying them so more.
Please give my best regards to Mrs. Herreshoff. I am delighted to hear from Charles that you are so well.

• Development Class (MIT Museum-made index card)
• Note: The vessel index cards comprise two sets of a total of some 3200 cards about vessels built by HMCo, with dimensions and information regarding drawings, later or former vessel names, and owners. They were compiled from HMCo's early days until 1920 and added to in later decades, apparently by Hart Nautical curator William A. Baker and his successors. While HMCo seems to have used only one set of index cards, all sorted by name and, where no name was available, by number, later users at MIT apparently divided them into two sets of cards, one sorted by vessel name, the other by vessel number and greatly expanded the number of cards. Original HMCo cards are usually lined and almost always punched with a hole at bottom center while later cards usually have no hole, are unlined, and often carry substantially less information. All cards are held by the Francis Russell Hart Nautical Collections of the MIT Museum in Cambridge, Mass.

A comparison of the two transcriptions can be particularly useful in those many cases where the handwriting in the Construction Record is difficult to decipher.

"Note that the HMCo construction record and MIT's vessel index card list #1149s as having been built for Junius Morgan while the HMCo-made Plan Index Card for plan 130-188 lists #1149 as having been built for George Nichols, as does the book 'Mystic Seaport Watercraft'. Pig in a Bag, which was owned by George Nichols and is owned today by Mystic Seaport Museum, should thus be assumed to be #1149s unless she carries a builder's plate stating her to be #1148s. Likewise, the Development Boat built for Junius Morgan should thus be assumed to #1148s and not #1149s.(The original ink on paper plan 76-164 (later renamed to 28-68, HH.5.2067) also carries a penciled note 'Com. Junius S. Morgan's with teak fittings', while the original ink on paper plan 76-165 (later renamed to 28-69, HH.5.2068) also carries a penciled note 'Com. Geo. Nichols with butternut fittings', confirming that, indeed #1148s was built for Junius Morgan." (Source: van der Linde, Claas. October 6, 2018.)
