[edit] Comment
in spanish: http://es.wikipedia.org/wiki/Submarino_Flach the article in which is based this page have several errors... the Santiago Times is not the best reference resource... please review it. i.e.: the Flach was the ninth submarine in the world, not the fifth... 1º "Turtle", 1775, USA 2º "Nautilus", 1800, France 3º "Halsey", 1814, USA 4º "Brandtaucher", 1851, Germany 5º "Alligator", 1863, USA 6º "Plongeur", 1863, France 7º "H.L. Hunley", 1864, USA 8º "Ictini II", 1864, Spain 9º "FLACH", 1865, Chile Where does that list come from? If it's from a reliable source, the article should definitely be changed accordingly. Yet for some reason I remember the "Brandtaucher" as the first submarine in the world, even though I can easily be wrong there. LoneWolfJack 09:17, 10 May 2007 (UTC) The Flach submarine is very unlikely to have had a weight-displacement of 100 tons.... more likely substantially less. One has only to calculate the cross section given a beam of 2.5 meters (assume circular cross section), multiply it by the length of 12.5 meters, to figure that this would give a volume of some 61 cubic meters... If the Flach weighed 100 tons, given a smaller displacement, it would have never floated.... and the sub was likely to have a "pointy" bow, not a flat one, which would reduce its displacement volume even further. Successful submarines need to float at times, and cannot displace less water than their weight (they change buoyancy by adding or reducing ballast...).
