Special nautical chart | Format: A3 (29.7×42.0cm) ring-bound | 16 pages | Scale 1:10,000
The special boat sports chart over the Koster Archipelago is based on our previous Koster charts in A2 format, but the area has been expanded and new sea measurements in the area have meant that we have been able to adjust depth curves and introduce several new grounds in the chart. The chart is also adapted to the new reference level RH2000 which is about to be introduced in the official charts. The scale is the same, 1:10,000, as is the content, with 2- and 3-meter curves, accurate depth information and land topography. What differs is the format: The special boat sports charts are ring-bound in A3 format according to the same principle as the Swedish Maritime Administration’s series of Boat Sports Charts. The material in Hydrographica’s special boat sports charts is Polyart, a synthetic polyester material with a paper feel. They are water-resistant and oil-resistant, writable and easy to wipe off. But, like regular nautical charts, the material is affected and the colors fade if they are constantly exposed to sunlight.
