Ship model
Ship models (or "model ships") are scale representations of modern or historic sea-going vessels.
Most ship models have traditionally been built of
wood. Today, though, many amateur kits are available for ship models made mostly or totally out of
plastic. A small number of model ships are constructed out of sheet metal.
The level of detail and craftmanship can range from crude "primitives" to more detailed models that achieve museum quality. Notable collections include the
Norwegian Seafaring Museum (
Norsk Sjøfartsmuseum) in
Oslo and the
Museu Marítim in
Barcelona, which has a full-scale (1
meter = 1 meter) model of a
galley.
History
\nThe art of ship modeling has existed since ancient Egypt, where they were used in burials and believed to carry the soul into the afterlife.
Some of the oldest ship models found have been those of early craft such as Galleys, Galleons, and possibly Carracks, dating from the 12th through the 15th centuries and found occasionally mounted in churches, where they were used to bless the ships and those who sailed in them. \nOther rare and often very crudely built models of that time period have found their way into collections at various museums around the world.
Despite the fact that some fine artists painted and sculpted masterpieces of architecture and the human and animal form, it seems that no truly representative drawings of ships seems to have survived from this period. \nMost surviving pictures or engravings are apparently greatly out of scale, although like maps of that period, they were greatly decorated with drawings of real and imagined sea monsters, leaving the nautical historian very little to work with.
Through the earlier centuries, and even into the 18th century, virtually all small craft and many of the larger ships were built without any formal plans being drawn. \nShipwrights were apprenticed to their craft at an early age and the art was passed down from father to son. \nShip models were being built by designers of large ships primarily to show their prospective customers how the full size ship would appear, and also to introduce advanced building techniques. \nFew shipping merchants could read a construction draft, and still fewer individuals were sufficiently advanced in the art of drafting or the mathematics necessary to that art. \nAdd to that the fairly primitive method of paper making, with its acidic product tending to discolor and disintegrate, and you will understand why so few ship’s plans survived outside of the Royal Shipyard in England, which to this day is a major source of information on ships of the earlier centuries.
Ship models often referred to as ‘Admiralty’ or ‘Shipyard’ models were built either before or during construction of many 18th and 19th century warships. Although many of these models did not illustrate the actual construction timbering or framing, they did illustrate the form of the hull and usually had great detail of the deck furnishings, masts, spars, and general configuration. Some of these grand models were decorated with carvings of great beauty and were evidently constructed by teams of artisans. \nThe labor they represent would have taken an individual many years to complete, providing you could ever find a competent ship modeler who was also capable of such fine carving. \nThey served to educate the non-seafaring types who were involved in the financing or some other aspect of the ship, to avoid construction errors that might have evolved as the ship itself took form, and more importantly, to demonstrate what a thing of beauty the real ship would be.
During the several wars between France and England, seamen who were taken prisoner were confined, sometimes for many years, and in their boredom, sought relief by building ship models from scraps of wood and bone. \nThis evolved into an art form and the models were sold to the public, which responded by supplying the prisoners with ivory so that the models would be all the more decorative. Rigging was made of human hair, horsehair, silk, or whatever other fine material could be obtained. \nFor the most part, the models had carved wooden hulls covered with thin veneers of bone or ivory, and other parts of the model such as masts and spars were also carved from bone and ivory. \nTo this day they remain highly sought after, valuable collectibles.
Ship modeling got off to a rather slow start in the United States. \nMany of the older models from the turn of the century, 1900 on, were models built by seamen who whiled away their off-duty hours whittle models of ships they were serving on. \nFew home craftsmen of the time attempted ship models because of lack of information other than an occasional sketch or photogravure in the local paper. In the mid 1920’s, ship model kits were introduced to the public and cast lead parts such as anchors, deadeyes, and rigging blocks became available. \nMagazines carried advertisements for these items, and the home craftsmen of the U.S. began to respond.
The big modeling boost came early in the 1930’s when Popular Science magazine began to publish a series of articles and plans of famous ships by E. Armitage McCann. \nThis was the true beginning of ship modeling as a popular hobby. \nIt was also the beginning of nautical research as we know it today, an attempt by model craftsman to upgrade their work by researching newly available documents to determine the historical correctness of the models they were building.
Today there exist national and international sources of ship’s plans, information as to dimensions, construction techniques, types of wood and other materials to use in the building of models. There are numerous books and periodicalsd evoted to the craft, and ship model clubs are now found in many cities around the world.
Basic types of contruction
\nThere are five basic types of construction used in building a wooden ship model hull:
- Solid wood hull sawn and carved from a single block of wood.
- Gluing together two thinner blocks of wood so that a block is formed with the seam vertical, so that the seam will show running down that surface of the block which is to be the deck. No advantage is gained by having the seam show along the sides of the hull.
- Cutting four or five thinner slabs of wood to be glued later into a laminated block. In this case, the slabs will be oriented so that they sit one on top of the other and the reason for this will be forthcoming in the explanation of this technique.
- Plank on bulkhead, a technique in which a series of shaped bulkheads are placed along the keel to form a shaped stage which will be covered with planks to form the hull of the model.
- Plank on frame In this technique, the model is built just as the full size wooden ship is constructed. The keel is laid down in a manner which keeps it straight and true.. The sternpost and stem are erected, deadwood and strengthening pieces inserted, and a series of shaped frames are built and erected along the keel to form the internal framework of the model. The planks are then applied over the frame to form the external covering.
Scale conversion factors
\n\nTable of Scale Conversion Factors\n| from | to 1/8 | to 3/16 | to 1/4 |
|---|
\n| 1/16 | 2.0 | 3.0 | 4.0 |
\n| 1/12 | 1.5 | 2.25 | 3.0 |
\n| 3/32 | 1.33 | 2.0 | 2.67 |
\n| 1/8 | 1.0 | 1.5 | 2.0 |
\n| 5/32 | 0.8 | 1.2 | 1.6 |
\n| 3/16 | 0.67 | 1.0 | 1.33 |
\n| 1.5 | 0.625 | 0.94 | 1.25 |
\n| 7/32 | 0.57 | 0.86 | 1.14 |
\n| 1/4 | 0.5 | 0.75 | 1.0 |

Instead of using plans made specifically for models, many model shipwrights use the actual blueprints for the original vessel. \nOne can take drawings for the original ship to a blueprint service and have them blown up, or reduced to bring them to the new
scale. \nFor instance, if the drawings are in 1/4" scale and you intend to build in 3/16”, tell the service to reduce them 25%. \nYou can use the conversion table below to determine the percentage of change. You can easily work directly from the original drawings however, by changing scale each time you make a measurement.
The equation for converting a measurement in one scale to that of another scale is
D2 = D1 x F where:\n* D1 = Dimension in the “from-scale”\n* D2 = Dimension in the “to-scale”\n* F = Conversion factor between scales
Example: A yardarm is 6” long in 3/16” scale. Find its length in 1/8” scale.\n* F = .67 (from table)\n* D2 = 6” X .67 = 4.02 =
4”
It is easier to make measurements in the
metric system and them multiply them by the scale conversion factor. \nScales are expressed in fractional inches, but fractions themselves are harder to work with than metric measurements. \nFor example, a hatch measures 1” wide on the draft. \nYou are building in 3/16” scale. \nMeasuring the hatch in metric, you measure 25 mm. T\nhe conversion factor for 1/4” to 3/16”, according to the conversion table is .75. So 25mm x .75 = 18.75 mm, or about 19 mm. \nThat is the hatch size in 3/16” scale.
Conversion is a fairly simple task once you start measuring in metric and converting according to the scale.
There is a simple conversion factor that allows you to determine the approximate size of a model by taking the actual measurements of the full-size ship and arriving at a scale factor. \nIt is a rough way of deciding whether you want to build a model that is about two feet long, three feet long, or four feet long.
Here is a ship model conversion example using a real ship, the Hancock. \nThis is a frigate appearing in Chappelle’s "History of American Sailing Ships". \nIn this example we want to estimate its size as a model. \nWe find that the length is given at 136’ 7”, which rounds off to 137 feet.
\n| 1/8 scale | Feet divided by 8 |
\n
| 3/16 scale | Feet divided by 5.33 |
\n
| 1/4 scale | Feet divided by 4 |
\n
\nTo convert feet (of the actual ship) to the number of inches long that the model will be, use the factors in the table on the right.
To find the principal dimensions (length, height, and width) of a (square rigged) model in 1/8” scale, then:
- Find scaled length by dividing 137 by 8 = 17.125”\n# Find 50% of 17.125 and add it to 17.125 (8.56 + 17.125 = 25.685, about 25.5)\n# Typically, the height of this model will be its length less 10% or about 23.1/2”\n# Typically, the beam of this model will be its length divided by 4, or about 6 1/2”
Although this technique allows you to judge the approximate length of a proposed model from its true footage, only square riggers will fit the approximate height and beam by the above factors. To approximate these dimensions on other craft, scale the drawings from which you found the length and arrive at her mast heights and beam.
Model shipwright guilds
\nPeople who work on building model ships often join together to form guilds; these guilds are intended to allow more experienced members the opportunity to pass on their knowledge to new members; to allow members of all levels of expertise to exchange new ideas, as well as serving as social function.
The USS Constitution Model Shipwright Guild, Boston, MA. \nThis club meets on the first Tuesday of every month in Building number 5 at the Charlestown Navy Yard, just one hundred feet away from Old Ironsides.
The Nautical Research Guild website states that "The Nautical Research Guild is an international organization of ship modelers, maritime artists, nautical archeologists and historians who are dedicated to enhancing the art and experience of ship modeling."
Guilds for those interested in buildin odel ships are found across the world.
