Adjustment of Aids to Navigation - Kattegat and Skagerrak

When the new Routing Measures in the vicinity of Skagerrak and Kattegat are being implemented on July 1 2020 the Aids to Navigation (AtoNs) system will be adjusted accordingly on both Swedish and Danish waters. A full list of the adjustment which includes removing and adjusting existing buoyage as well as establishing new Buoys including virtual AtoNs are to be seen on this site together with Map Sketches.

Some of the adjustments have already taken place throughout the spring of 2020 and the rest of the adjustment will take place up to the implementing date of July 1. The adjustments are promulgated in Danish and Swedish Notices to Mariners.
