Youth and early career

Chapman was born at Nya Varvet, the royal dockyards in Gothenburg, on 9 September 1721, the son of Thomas Chapman, an English naval officer (born 1679 in Yorkshire

 in 1716. His mother was Susanna Colson, the daughter of London shipwright William Colson. He showed a talent for shipbuilding when he made his first body plan based on a drawing of an Ostende privateer given to him by Flemish shipwright. Chapman went to sea in 1736, at the age of fifteen, and spent his late teens working in both private and state shipyards. In 1741, he helped build a Spanish merchant vessel, a project that provided him with enough money to allow him to work as a ship's carpenter in London 1741-44. After his stay in England, he returned to Gothenburg and established a shipyard with a Swedish merchant named Bagge. Together they built a few small vessels and provided maintenance work for the Swedish East India Company

Education

Though he had a received a good basic education in shipbuilding, Chapman recognized that he did not possess the knowledge of higher mathematics that was required to determine draft and stability at the design stage of a vessel. In 1748, he sold his share of the shipyard and moved to Stockholm where he studied for two years under Baron Palmqvist. He went on to study under the English professor of mathematics, Thomas Simpson

Chapman recorded his extensive research of British shipbuilding in several documents, including an 8-page handwritten document titled Directions for Building of a Ship of 50 Guns, where he described construction methods as well as the British method of launching ships. His activities attracted the interests of the British naval authorities and upon leaving Deptfort in 1753, he was arrested, his papers confiscated and was then charged with trying to lure shipyards workers into French service. France and Great Britain were at the time bitter rivals, and both Sweden and Denmark were active in uncovering British manufacturing methods as well as trying to persuade British shipwrights into their service. Chapman was kept under house arrest for about one month at the cost of half a guinea

In 1754, Chapman continued his educational tour by going to the Netherlands and in 1755 to France, where he was given permission to stay at the royal shipyards at Brest

and the 64-gun Bienfaisant and pen and ink drawings of ship decorations. The experience in Brest is believed to have made a deep impression on Chapman, later contributing to his conviction that 60-gun ships were the most appropriate for Swedish service.

The French authorities were the first to recognize Chapman's skills and attempted to convince him to stay and enter service for France, an offer he declined. After Chapman returned to London in 1756, the First Lord of the Admiralty tried to do the same, and came close to succeeding by using patriotic appeals to Chapman's British heritage. In his memoirs, Chapman wrote that he would likely have stayed had the current First Lord not lost his office soon after their meeting. Instead, he was recruited by the Swedish minister in Paris, Ulrik Scheffer, later Minister of External Affairs under Gustav III.

In Swedish service

Soon after his appointment, he drafted his ideal plans for docks, which included facilities for properly ventilated sail storage and advanced dock pumps that could be powered by human power, horses or wind mills. The plans would, however, not be realized until much later, when Chapman was made chief shipwright of the Karlskrona yards.

In November 1758 to April of 1759, he was charged with a timber inspection cruise along the coasts from Turku

By closely examining drawings of ships with known good sailing qualities Chapman realized that the framework should be divided in a certain progression. The frames should decrease from the place of greatest width in the same relation as the ordinates 0, 1, 2, 3, 4 etc (pictured), where the arc ABC is a parabola, AD is the axis and A is the vertex

 (the "peak"). This construction method is called the "parabola method". Chapman also introduced the so called "relaxation method", but preferred the former himself.

At Sveaborg, Chapman supervised and led the construction and expansion of the naval yards, including cranes, docks and various buildings. He moved to Stockholm in 1764, but remained in charge of the design of vessels for the archipelago fleet. He was also made a part of a commission that was to propose improvements on the expansion of the high seas navy. Its final report was presented in 1764 and recommended new designs for standardized ships of the line

 varying from 50 to 70 guns. The report represented the ideals of a new school of shipwrights that favored scientific methods and the use of theoretical models at early stages in ship design, a view that was in conflict with the old school of shipbuilding which favored slow evolution based on practical experimentation. The old school, represented most prominently by Gilbert Sheldon, came into conflict with the new ideas, but lost the debate when the Board of the Admiralty favored the findings of the commission at the Riksdag

 provided the capital while Chapman would contribute his technical skills and experience with shipbuilding. The same year he moved in to a newly built house in Djurgården with his nephew Larg Bogeman and Elisabeth Lindborg, his former housekeeper with whom he had a daughter and son. Chapman constructed a new type of saw mill for the Djurgården yard that replaced the traditional "saw pit" with a circular blade at the center of an octagonal building. A system of chains and pulleys would pull lumber toward the saw, which could receive them from eight different directions.

The Djurgården yard produced several of Chapman's own designs that were successful, including cats, barque

 of France, Gustav took great inspiration from the "Sun King" Louis XIV (1638–1715) and allied himself with his successor Louis XV.

Chapman supported the king's boldness and even gave concrete assistance by warehousing ammunition for troops that were loyal to the king. The maneuver paid off since Gustav supported an expansion of both army and navy and singled out Russia as the primary enemy of Swedish interests. The alliance with Louis XV meant that large French subsidies were sent to expand the Swedish military against the common Russian enemy. This provided the funds to finance Chapman's plans to expand the navy with 60- to 70-gun warships of his own design.

Navy expansion

In 1776, Chapman became a civilian member of the Board of the Admiralty. His influence on the board and favor with the king resulted in critical reports of the current habit of the high seas navy to keep old ships afloat at great expense rather than spending more resources on building new, improved ships. Chapman's recommendations for improvements of the Karlskrona facilities was also received positively and approved by the king. The same year he was elected into the Royal Swedish Academy of Sciences

 as member number 175.

An expansion of the navy was seen as necessary, but the design of the new ships was still a matter of debate in the late 1770s. The old school of shipwrights, most prominently supported by the Sheldon family and senior navy officers like Admiral Carl Tersmeden

 and the court, pushed for more radical changes and designs based on the theoretical designs and experimental physics and mathematics. Chapman's first proposal for a new standard for ships of the line was the Wasa, completed in 1778. Its superstructures were lowered considerably by removing the poop deck

 and the gun decks were placed higher than in older designs to allow them to be used even in rough weather, when the ship rolled.

The Wasa went through sea trials in 1779 where it was compared with Sofia Magdalena, a ship of the older design which was favored by the conservative factions within the establishment. The Wasa to some degree outperformed Sofia Magdalena, but never completely outclassed it. The opposition took advantage while Chapman was convinced he needed to make only minimal adjustments to his design to produce a vastly superior warship. The portrayal of the conflict as conservative reactionaries versus progressive pioneers is shared by several historical authors, including Daniel G. Harris

 has argued this description is partial to Chapman and his supporters and stressed the political nature of the conflict; Chapman and af Trolle were both close to the royal circles and their aims coincided with those of king Gustav III, who wished to assert control of the armed forces and to portray himself as an enlightened monarch who encouraged innovation against the conservative navy establishment in Karlskrona.

Chapman also worked out several improvements of the royal shipyards that he supervised, including recommendations for the use of sheds to protect ships from deterioration when they were in reserve, something that was particularly important for the often lightly built galleys. Showing considerable organization skills, he made detailed plans on how to make naval vessels ready for quick mobilization and proposed a more efficient system of management for shipyards based on his experiences in Sweden and abroad.

, water resistance, the center of gravity of hulls, stability and tonnage.

In order to test his mathematical theories, he had a 100 m long pool constructed outside Karlskrona, where he tested various hull designs with scale models. The models were pulled through the water with pulleys and ropes. This method gave realistic values and is similar to the method used today to establish the hydrodynamic features of new hull designs.

Architectura Navalis Mercatoria

In 1765 Chapman applied for permission from his work as a chief naval builder for the Archipelago Fleet at the naval base at Sveaborg to work on Architectura Navalis Mercatoria, a collection of contemporary ship types that he considered to be the best and most interesting. The work had been commissioned by Duke Charles

, the brother of king Gustav and was published in 1768. The book contained 62 illustrations of ships and smaller vessels, both Swedish and foreign designs. Some of these were Chapman's own designs, but many were also types that he had seen during visits to foreign countries. Everything from large warships to small fishing vessels were represented.

The book was intended for an international audience and the text was available in Swedish, French and English. All measurements were given in Swedish, French and English feet. However, it took seven years to finish the accompanying explanatory texts. The charts and the following Tractat om Skepps-byggeriet ("Treatise on shipbuilding") in 1775 launched Chapman as one of the leading experts on ship building in the world.
