1815 - Howe, wholly built upon Diagonal Bracing System
Howe, 120-gun Ship of the Line Robert Seppings, 48 years old, previously Master Shipwright at Chatham dockyard, now Surveyor of the Navy for two years, applied his system of diagonal bracing to the whole hull of a new ship, Howe, a tremendous 120. He also used iron knees in substitution for grown timbers, so difficult to find within sparse woods. ¤ In England as in France, loggers stride over stands of oaks in search of curved boughs that could become wooden knees to suppo

1854 - Maiden Voyage for Clipper Lightning
Lightning It has been said that enthusiasm for clippers was waning lately. No doubt that experts question the future of clipper against steamer on the long run. Yet the clipper is in full boom today, thanks to China tea trade, to California gold rush and to Australia gold rush, which have urged fast transport as well as mass migration. China, California and Australia are still too far to expect reaching them through steam navigation, There are meant to clipper runs as fas

1803 - Emergence of Steam Machinery at Portsmouth Dockyard
Block Mill The Block Mills have entered service at Portsmouth dockyard. This is a decisive step for the introduction of steam engines into shipyards. Two centuries after the introduction of wind-powered sawmills into Zaandam works, we are attending the advent of a new era of mechanisation in shipbuilding. ¤ Cornelis Corneliszoon van Uitgeest is the inventor of the wind-powered sawmill, which swiftly developed during the first half of the 17th century in the United Province

1808 - Launch of 120-gun Caledonia
Caledonia in two positions Caledonia has just been launched. She is the first 120-gun man-of-war of the British navy. She supersedes the previous giants, two 110-gun vessels, Ville-de-Paris and Hibernia. It was decided to build her in 1797 under the feeling that larger ships were necessary to face the French three-deckers, especially the tremendous 118s designed by Jacques-Noël Sané twenty years ago. ¤ At the battle of the Glorious First of June (1794), the 110-gun Révolu

She is meant to fast trade travels between Maryland and the West Indies. She displays a long bowsprit fit for multiple jibs, raked masts carrying large gaff sails, a stem and a stern both raked, and a V-shaped hull. She is 90-foot long and 29-foot broad.

1822 - Iron Steamboat Aaron Manby Crosses the Channel
Charles Napier Aaron Manby, named after the master of the Horseley Ironworks, Aaron Manby, 46, is a small 116-ton iron-hulled steamship. Jointly designed by Manby, by his son Charles, 18, and especially by Captain Charles Napier, 36, she was launched last year. She is up to date of innovation. She is obviously meant to prove validity of Napier's conceptions and of a Manby's invention. ¤ Manby is a talented civil engineer. In 1813, he patented a technique to form blocks o

John Stevens For the first time a 50-foot long steamboat, the Phoenix, has sailed the open ocean, over 120 miles from New York to the mouth of the Delaware river. Then she has gone upstream over extra 90 miles to Philadelphia. The journey has been done under steam solely since Phoenix is deprived of sail. As everybody knows, Robert Fulton's partner, Robert Livingston, 63, obtained the monopoly of navigation on the Hudson river as early as 1798. The success of the steamboat
