Adlard Coles, 1st. Eng. Ed., 1971. 104 pp., + 62 (fldg.) plates. D.j., 34 x 24cm. V.G.+. This classic eighteenth century Treatise on Shipbuilding was first published in Stockholm in 1768. This bi-centenary facsimile edition was first published in Germany in 1968, and in England in 1971 (with later reprints following). Chapman was a great pioneer in the field of naval architecture and did much to turn shipbuilding into a science. This work ran into many editions and foreign translations, becoming virtually a manual of ship design for the late 18th and early 19th centuries. Fredrik Henrik af Chapman (1721-1808) was a legend in his own lifetime, not only in his native Sweden but also in England and elsewhere. In 1764 he was appointed Chief Shipbuilder to the Swedish Navy and for a period studied in London where he acquired the art of copper etching. The main feature of this book is to be found in the 62 large folding plans which include draughts of merchant ships, vessels designed for swift sailing and rowing, armed privateers, and men-o'-war. In addition, the different methods of launching ships are illustrated, as employed by the French, English and Dutch. The Treatise on Shipbuilding completed several years later is also given. This was translated into French in 1779 by Lemonnier and in 1781 by Vial du Chairbois. In 1813 the Rev. James Inman translated it into English and early that century it went into Russian and in 1864 into German. Today this work is invaluable to those interested in the design and construction of 18th century ships and also of immense value to model-makers. Original 18th century editions of Chapman's work sell today for thousands of pounds.
