Special charts | Format: A2 (42.0 × 59.4cm) blank / unfolded | Scale 1:10 000
Hydrographica produces detailed special charts at a scale of 1:10 000 over difficult-to-navigate areas where official charts are insufficient. They contain significantly more and more accurate depth data, have detailed depth curves for 2 and 3 meter depths respectively and have elevation curves on land. The special charts have a scale of 1:10 000 and are printed on Polyart, a synthetic, very tear-resistant polyester material with a paper feel, which is made for boat use. The charts are completely water-resistant and oil-resistant, writable, easy to wipe off and they can be folded thousands of times without being damaged. But as with ordinary charts, the material is affected and the colors fade if they are constantly in front of sunlight.
