Vertical clearance as given on the chart.
At bridges over navigable waters are notice boards stating the height of the obstruction in metres. This height is called “vertical clearance” and is calculated in the following way:

The distance between “Mean high water” and the lowest part of the obstruction, within the navigable channel, reduced by a safety margin of 0,5-2,0m depending on expected swell in the area.

Low bridges across sheltered waters
is given as the actual height of the bridge above mean sea level without the safety margin.

Low bridges are those where the clearance can easily be estimated from a small boat i.e. up to approximately 3m in height.
