UNDERSTANDING HALF HULLS
by Land And Sea Collection

If you are considering investing in an authentic shipbuilder's half hull, these are some things you should know.
When you are done reading, you may want to view our current vintage and antique half hull models. Click http://www.landandseacollection.com/id517.html

Antique builders model of a coal collier, 47 1/2" L x 10 1/4" H x 6" W, Ca 1890, SOLD!


There are a number of different types of authentic half hulls, all of which had different uses and applications. It is helpful in evaluating a half hull to be aware of their use so they may be compared to others of the same type and to contemporary reproductions. Many pictures of the models in this section, unless otherwise noted, have been sold.

BUILDERS CONSTRUCTION HALF HULL:
This type model was made for the purpose of establishing the shape of the vessel, and was constructed out of a series of planks called "lifts" which were joined together using dowels prior to 1820 or by screws afterwards. When disassembled, the individual lifts were laid on the floor and expanded to full size in a process called "lofting". From these shapes timbers were cut, and frames and strakes were assembled to build the full size vessel.

Builder's construction models
are rare, old, are varnished rather than painted, and devoid of detail. They are one off, large rather than medium to small size, and they always can be taken apart. If the name of the vessel is known, their value is greater. The varnished wood has generally mellowed with age and has a rich dark patina. Their value increases with the prominence of the vessel if known, the size of the hull, and of course, most important, its condition.

Builder's construction plating models
were used to lay out the location of the ship's plating when construction changed from wood to iron and then to steel.
What is confusing is there are various types of BUILDER'S MODELS which don't have all those characteristics. Builder's DISPLAY MODELS don't come apart, but were made by builders, either to present to the ship owners or to be used as displays of completed ships in the builder's offices or at trade shows for sales promotion. Consequently. they may be done in much greater detail, have painted hulls and other embellishments that make them more visually appealing. Models of merchant ships enclosed in glass cases can sell for $15000.00 and more.

BUILDER'S PRESENTATION HALF MODELS: were made to be given as gifts to the party contracting for the vessel such as a steamship company, yacht owner, government etc. They also were used at trade shows and in the builder's office to demonstrate their capabilities and as a visual record of the ships they had built.

The example in this listing and this half hull of the SS OITHONA have all the characteristics of a true builder's presentation model.

Builder's Model S.S. Oithona, above, Dated 1850, 60" L x 11 3/4" H x 4" W, Served in Australian Trade, SOLD to New Zealand

This example is of a authentic builder's construction model of the Schooner Mermaid. It was made by its master builder and handed down in his family in an unfinished state. After much deliberation, our shop finished it as he would have done.

And this one is of a yacht, the Fishers Island 23.
It is both a builder's construction model, but was later finished in paint, and became a builder's display model. The model and the yacht were made by the famous Herreshoff Manufacturing Company of Bristol, RI, around 1931. It is
The model's dimensions are: one inch equals one foot:
LOA 33 1/2" LWL 23" Beam x 2 = 7" Draft 4" SOLD

IN A NUT SHELL: Block and half block models became more common after 1720 and builders made these to illustrate the designs provided to them by engineering firms. For ease of use they were held together by dowels. By the middle of the 1850s half block models were common in commercial shipyards, and the use of wood screws had replaced dowel. If you come across a model held together with dowels you know you have something worthwhile. They were used as aids for framing, planking and plating ships. By the 1880s, more were being made for display only as being representative of the builder’s or naval architects capabilities.

LIFT METHOD:
Half Hulls were carefully hand carved, and incorporated the latest in the designer's knowledge of which shape produced the fastest and most seaworthy vessel. They are usually made using multiple layers of wood, stacked one on top of each other on a horizontal plane, called lifts. The lifts were made to be taken apart, and were used as a template to lay off the lines on the floor. These were then enlarged to the vessel's full size in a process that was called "lofting".

BUTTOCK METHOD:
In this method, the concept is similar, but the lift's are placed together on a vertical plane, and instead of describing the shape of waterlines, they show the shape of the vessels buttock's or cheeks. When translated into an elevation drawing, the buttocks appear as curved lines and the stations and waterlines appear as straight vertical lines. This is in contrast to a plan view of the vessel's shape where the waterlines are shown as curved lines and the buttocks and stations as straight lines. Both types of modeling are shown in the diagram below.

This half model of the Royal Yacht Squadron schooner Titania is an example of a "buttocks model". SOLD!

If you're still trying to make a decision, consider the space where the model will be displayed. If you have a lot of wall area, you want a large model to carry it. The opposite is also true. Also consider how much you really want to spend. There is a big difference in price between the various types of half hull models
