Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded5.39.217.77:8898) I1 U/ b: V+ p% d! q - p( s; F9 ]/ C7 y% etvb now,tvbnow,bttvb5.39.217.77:8898/ C- E.

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. 6 A1 G' g+ d: R' c% N
