Hydrographica produces highly accurate specialized nautical charts of difficult-to-navigate areas. The charts are fully redrawn and produced by processing current aerial images supplemented by extensive field measurements and the charts open new, safe routes in previously "closed" areas. The special sea charts are made with permission from the Swedish Armed Forces and the Swedish Maritime Administration.
The card is in A2 and printed in Polyart, an environmentally friendly plastic with a paper feel, making it completely water resistant and very durable.
A perfect special card to have in the boat when you want to discover the area!
