To Build or Not to Build According to Howard I. Chapelle

A seminar course within The School for Ship Model Building​


This course will focus on a couple of articles written by Howard I. Chapelle that appeared in the pages of the Nautical Research Journal. I believe these were published in 1951 and 1952. The articles, with links to them (as well as PDF download), are titled:

Analyzation / discussion related to these documents is nothing new - the included views have been debated (sometimes hotly) since publication. With that said, issues that Chapelle brings up are important and core to the field of model shipbuilding. In the past discussions that I am aware of, it seems that the two papers are dealt with in some isolation. Here I hope that we can extend the discussion to include additional related writings of Chapelle and to make an attempt on understanding the context / situation that he wrote from.


Supplemental to these articles, I would like for us to consider the introductory material written in the book:

  • American Ship Models and How to Build Them by V.R. Grimwood (1942)
As well some content from:
  • The National Watercraft Collection by Howard I. Chapelle (1960)

Additionally, it will be valuable to consider the 1960 publication by Chapelle:


Other readings my be suggested later.


My name is Greg Davis and this course offering has been suggested by Dave Stevens. Certainly there are individuals that know more about Chapelle and his views on model ship building than I will likely ever know. Nonetheless, I believe that I can help guide the journey of analyzing the topic at hand. Hence, I feel that my primary role in this class / seminar is to be the facilitator.

Professionally my background is in the field of Mathematics, specifically Dynamical Systems. I served as a professor and administrator at the University of Wisconsin – Green Bay for 35 years. As an instructor and scholar, I did find success in creating and analyzing mathematical models. Because UW-Green Bay is not a huge University, I had a unique opportunity to teach more than 30 different courses at levels from introductory to graduate. I’ve found that several of the skills needed in the academic arena are transferable to topics related to building model ships; and certainly, to managing a classroom.

As far as my experience in model ships is concerned, it is a work in progress, and truthfully, I hope that is always the case. I’ve been actively engaged in building model ships for about 20 years now. I started by building a number of kits that ‘shouldn’t be built’. But soon, and in a modeling vacuum, my academic instincts kicked in and I have found myself more and more concerned with historical accuracy of my work as well as looking for interesting and unique projects. While I still make some kits, my focus is much more aligned with that of a scratch-builder creating historically based models. In fact, the last model I completed did require me to do much research on the subject and draft reconstruction plans prior to building the vessel.


I'm going to give this introduction a day or two to be seen and then I would like to get the discussion going in a (semi) structured manner.

Thank you for considering this course offering and the possibility of contributing and I seriously look forward to contributions from all involved!
 
This is a short bio of Howard Irving Chapelle that is on the Smithsonian Institution Archives website. From the dates in the bio, I surmise that he wrote the two NRG papers (to be discussed in this thread) at or just after the time he visited England on fellowship.

Historical Note​

Howard Irving Chapelle (1901-1975), marine architect and historian, began his career as a marine apprentice and designer in 1919. He worked for a number of shipbuilders until he went into business for himself in 1936. During this period, Chapelle also served as head of the New England section of the Historic American Merchant Marine Survey, a Depression-era project to gather information on American maritime history and provide work for destitute marine architects.

Chapelle's business was interrupted by World War II, during which he served in the United States Army Transportation Corps ship and boatbuilding program. Following the war, he pursued his interest in the history of marine architecture, traveling to England in 1950 to study colonial ship design on a Guggenheim Fellowship. In 1956-1957, Chapelle went to Turkey under the auspices of the United Nations Food and Agricultural Organization to serve as a consultant to the Turkish government on fishing vessel construction and fitting.

Chapelle was appointed Curator in the Division of Transportation, National Museum of History and Technology, in 1957. He served in that position until 1967 when he became Senior Historian. While at the Museum, he directed the planning and construction of hundreds of ship models for the Hall of Merchant Shipping. Chapelle retired in 1971, becoming Historian Emeritus in the Museum. A prolific writer, Chapelle authored a number of books on maritime history and marine architecture.
 
A great start, but if you "like to get the discussion going in a (semi) structured manner," I'm afraid you're going to find managing this student body to be a lot like herding cats! :D

Thanks for Chapelle's monograph on Savannah. I had not seen that one before. An excellent example of the sort of models serious modelers should be building.

But I’ve wrangled a Faculty Senate with success! So I’m not worried yet.
 
Howard Chapelle was a Naval Architect. I’m not aware of any models that he built himself, but like many naval architects he was interested in them. Naval Architecture is a recognized branch of engineering, and today involves formal education. The curriculum emphasizes design of the vessels hull and the means to predict performance by mathematical analysis. Although not stated in the biography, I believe that he did study Naval Architecture in the 1930’s via a well regarded learn by mail program.

Chapelle objected to people modeling vessels without historically accurate design information. He was especially critical of those who tried to reconstruct hull lines. He himself had reconstructed the lines of the Lake Erie Brig Niagara for a replica (not the current one) and felt that he had not got them right. He argued that a correctly shaped hull was the key to a worthwhile model. His Naval Architect’s credentials were showing.

While I agree with most of what Chapelle, has written, we have learned much since he wrote it. This is especially true of our British and European colleagues who have been able to analyze ancient shipbuilding texts held in their archives. Information from these texts plus an explosion of archeological information has permitted much better reconstruction of vessels largely unknown in his time.

This is partially why I felt it important to put this discussion / class in some form of historical context. He was active in the ship-building field over a century ago and the two main papers that are often debated are now 75 years old. The Savannah document was published in 1961 - so about a decade later. I also believe he was not a model builder, but given his position and the fact that he wrote the Savannah document, it seems he may have had some control over the model's outcome. We can address this later in the course; however from my first readings of the Savannah document, it seems that a number of his tenants were violated.

I have been thinking about what he might be thinking about the current state of ship modeling. Would he be encouraged - or additionally discouraged?

No matter, it is abundantly clear that Chapelle carried out an impressively vast line of historical scholarship - one that many should be / are indebted to.

His views have and continue to be polarizing in the modeling arena (I have no good idea of his impact in actual ship building). Here, I am looking for a better understanding of his views - particularly on how they may have actually affected him. I have some conjectures that I will raise when it seems time. Also, I have some hope that there may be some realistic way to plot a way forward so that some individuals can realistically make modeling contributions that are consistent with Chapelle's desires. I say some, because I don't see it realistic that all modelers need / can follow his doctrine. The ideas I have, do require collaboration beyond the modeling world.

Thanks for chiming in!
 
Well you caught my interest, thanks for posting. :) I did a quick look at the ships that should be built and liked the comment that if one wants a vessel commanded by Nelson, his first command, Badger (12) purchased 1776 and lines taken off in 1777, would be a great alternative. I checked RMG and there are deck drawings as well as the profile and body plan plus all her scantlings and dimensions of her masts and spars. Unfortunately they are low resolution, but can be purchased in high res from RMG.

Looking forward to further general discussions. My concern is that Chapelle seems to have had pretty strong feelings that only scratch building can yield an accurate model if based on accurate, contemporary sourced, information and based on the many kit-builds out there he may be correct for the most part, a few kit manufacturers and kit bashing aside. That said, the audience here and elsewhere may be a tiny fraction of membership. I hope that I am dead wrong about that.

first and foremost, i would like to welcome Greg Davis to the faculty of the School for Model Shipwrights. This is his classroom and lectures hall so i ask you all to respect that. This is an open discussion and a place to offer your point of view, ask questions, request further explanations so on and so forth. We are here to learn a thing or two.

A great start, but if you "like to get the discussion going in a (semi) structured manner," I'm afraid you're going to find managing this student body to be a lot like herding cats!

but if you crack open a can of cat food believe me you will have the attention of every cat in the room.
the audience here and elsewhere may be a tiny fraction of membership. I hope that I am dead wrong about that.

it is not really a tiny fraction. regardless of what you doing scratch building, researching, kit building model engineering whatever, there is a common ground and thread that runs through the art and hobby. There is a philosophy and a passion and the why and how.

I agree, I have read more forums than I can count by first time wooden model ship builder where they are asking how can I make my model more realistic / historically accurate. In fact, from what I've seen modelers that don't ever ask that question are the ones in the minority.

It appears I am, as I had hoped, dead wrong. :) I really hope everyone follows this topic.

Yeah BUT!

My completely unscientific tally of ship model builders wishing to improve the accuracy of their kit built model goes something like this: “What kind of knot should I use to tie the gun whatszt to the bilge whoszt.” I have yet to read a question asking if the hull shape is correct before buying a kit.

Chapelle approved of models that met certain basic standards, beginning with hull form. He tended not to worry about trivial details.

On the topic of Mathematical Modeling and Ship Modeling

Still giving some time for people to 'discover' this class. In the meantime I'd like to share where my mind sometimes goes!

At times I think about the parallels between the ‘art’ of mathematical modeling and that of model ship building.

The University of Wisconsin – Green Bay was established with relatively unique academic configuration. The budgetary units were connected to interdisciplinary units as opposed to the standard method of connecting to disciplinary units. At one level I was a member of the Mathematics Program, but the program did not have a stand-alone budget – my salary line ran through the Department of Natural and Applied Sciences for most of my career (toward the end of my stay, it was shifted to a newly found Department of Engineering, Mathematics, and Computer Science). The reason I mention this is that I worked in an environment where my immediate colleagues were trained in Biology, Chemistry, Engineering, Computer Science, Earth Science, Mathematics, and Physics. Our budgetary unit’s (NAS) unifying topic was that of Environmental Sciences – from both physical and ecological perspectives. As you might expect, Unit meetings could be ‘interesting’ when trying to balance the needs and desires of such a group.

Curriculum for an Environmental Science program is not defined by programmatic accreditation nor has any national / international standard. So, the curriculum was often in flux and the reason for a particular required (or elective) course may have ranged from this is good for the student to this is my field and I want to teach it. At times it was hard to argue for curricular change based on changing needs of students as they looked to (oh horrors) being employed. There was always a group of faculty that would say I don’t know that / didn’t have that material and I’ve been successful, so students don’t need that either. Did they ever notice that times do change and/or maybe they would have been even more successful with some additional knowledge! There were fights over GIS, scientific computing, and even mathematical modeling (surprised you are).

While supportive of GIS, scientific computing, scientific writing, my personal curriculum battles came with developing mathematical modeling courses and requirements. I eventually developed three courses that became requirements – an ecological modeling course and a physical modeling course for undergraduate students, as well as a graduate level course for the M.S. in Environmental Science and Policy.

I still remember my first offering of the required ecological modeling course because of the number of students resistant to the topic – some of this coming from their holding of other faculty members in an unrealistically high level of esteem. I also remember that one of the ‘resistant’ students became a graduate student of mine. His studies eventually found him off the coast of California studying bird populations. The group/project we were working on required that he needed modeling skills. In fact, that aspect of his thesis was instrumental in his future employment that he became quite successful in. So, all good with him! I will also say that as certain faculty retired and the modeling courses were no longer ‘new’ to the curriculum, the instruction became easier.

Mathematical modeling requires that one takes careful observation of what is to be modeled. The purpose of the model needs to be accessed. Hypotheses imbedded in the model need to be known. Decisions need to be made as to how accurate the model should be. Models need to be analyzed and verified. Mathematical modeling is often an iterative process:

Hypotheses are made; model is created; model is analyzed / verified; perhaps predictions are made based on the model. But no matter what, the result is always the same – the model is wrong. Hence hypotheses are made; model is created … .

It is a most basic fact: Models are not the real thing; they are always wrong.

So, why would one make a mathematical model? While a good model is the goal, it turns out that a bad mathematical model is also useful. When a mathematical model fails, it is because the assumptions are wrong. The failure should force the modeler to reassess the hypotheses (often requiring additional research) and therefore better understand the system that is being modeled. It is through this iterative process that mathematical models get better.

The process can take a long time; it can take many people with a shared goal. A great example is Newtonian mechanics being followed by Einstein’s theories being followed by … .

Perhaps, in the realm of historical ship modeling a similar process is hoped for. Inaccurate models can be informative because they demonstrate an element incorrectly – and this is sometimes easier to see than something that is correct. In the next model made, it is important to not replicate the inaccuracy. But how does the iterative process gain traction? Is it by an individual making a new model of the same ship, or is it the next modeler making a new model of the same ship? How often is credit given to a modeler for attempting a previously unmodeled ship; perhaps generating additional interest in the craft and future more accurate models of the ship. Or does the initial model need to be exceedingly well done, else the model is ignored, or worse condemnation is bestowed. In academics, credit should/would be granted – but historic ship modeling is not always academic (nor should it be). Nonetheless more people may be willing to stray from kits if they receive appropriate credit for doing so. Be sure, I am not proposing ribbons / awards for showing up!
 
Here is another Chapelle publication of interest; it describes the research associated with Fulton's "Steam Battery". This vessel was designed to disrupt / breakthrough the British Navel blockade along the East Coast during the war of 1812. The publication describes history of the vessel, the discovery of plans in the Danish Royal Archives in Copenhagen, as well as a reconstruction so that a model could be made of the ship.

I find this paper, much like Chapelle's publication on Savannah, to be valuable since it illustrates reconstruction techniques for model construction that would have been acceptable to him.
