YES indeed. This was not the first time for me either. Even if you dont find the 5 meter curve all the way there it is rather likely safe in the middle for our ships -- but when you are meeting ships heading south.....

By the way - my draught is almost like yours -- 1,83

maybe my point is: THE BOTTOM IS SUPPOSED TO BE SAND. IF NOT SAND MUD OR MARSH,,,,,, BUT I HIT HARD CONCRETE OR STONES LYING SHALLOW...MAYBE EVEN MORE SHALLOW THEN 1,5....
