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

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

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

1819 - A Steamship Crosses the Atlantic ocean, Three Days only under Steam
Moses Rogers It has been three years only since the steamship Elise crossed the English Channel. Thus it was extremely daring that somebody considered crossing the Atlantic ocean under steam so early after a short trip in comparison. His name is Moses Rogers, 40 years old now, born in the port of New London, Connecticut.
