Specialsjökort | Format: A1 ( 59,4cm×84,1cm) | Skala 1:20 000
Hydrographica produces detailed special charts at a scale of 1:10,000 over difficult-to-navigate areas where official charts are inadequate, but please note that this chart 121-01/02 North Vättern Archipelago has a scale of 1:15,000. It contains significantly more and more accurate depth information, has detailed depth curves for 2 and 3 meters respectively and has contour curves on land. The special charts have a scale of 1:15,000 and are printed on Polyart, a synthetic, highly tear-resistant polyester material with a paper-like feel, made for boating. The charts are completely waterproof and oil-resistant, writable, easy to wipe clean and they can be folded thousands of times without damage. But, like regular nautical charts, the material is affected and the colors fade if they are constantly exposed to sunlight.
