These norms should be seen as maximum values and may need to be changed in regards to vessel type, wind direction and other circumstances.
Reservation must be made with regard to a number of additional factors that affect the assessment of the individual case, e.g. reduced visibility, high wind speeds, currents, the ship's technical standard, the fairway's marking for night navigation, tugboat assistance, which may lead to a reduction of the guideline values. Under favorable external conditions, ships with very good maneuverability and high technical standards may be allowed to exceed specified guideline values.
