Lusitania (1805 Ship)
''Lusitania'' was a British merchant vessel launched in 1804. She emerges from the general background for two notable events in her history, one in 1813 when the French Navy captured and released her, and then between 1826 and 1830 for a whaling voyage. She was probably wrecked in 1834. Career ''Lusitania'' first appeared in ''Lloyd's Register'' (''LR'') in 1805. On 27 August 1807, Captain John Carman received a letter of marque for ''Lusitania''.Letter of Marque, - accessed 14 May 2011. On 16 November 1809 the captured ''Lusitania'', Carman, master, at .

Builder's Old Measurement
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam (nautical), beam. It is expressed in "tons burden" ( en-em , burthen , enm , byrthen ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in foot (length), feet, from the stem (ship), stem to the sternpost; * ''Beam (nautical), Beam'' is the maximum beam, in feet. The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom. The Moorsom system calculates the cargo-carrying capaci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
