A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded" [- C7 g5 C2 |- F1 v. _ 4 c; u8 J3 h.

At 918 meters, it is the longest navigable aqueduct in the world.www2.tvboxnow.com+ l) B2 f" W! Z) E- a- u% H
The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. www2.tvboxnow.com2 ]6 _5 {4 D* o, t5 ~
