GPS navigation, routes, favourites, storm warnings and SOS are never behind the paywall. COVERAGE Base charts and sea marks cover every sea on Earth. Depth shading and 3D seabed relief are worldwide. Depth contours are drawn wherever the underlying data is solid enough - across all oceans, with the densest coverage in European waters. Where it is not, the map deliberately shows no contour. IMPORTANT This app is not a substitute for official nautical charts. It must not be used as the primary means of navigation on vessels subject to IMO/SOLAS. Do not base navigation decisions on this app alone. Always carry official charts and comply with national and international regulations. DEPTH INFORMATION - PLEASE READ Depth information in this app comes from publicly available third-party data. Its coverage and quality are not the same everywhere: some sea areas have been surveyed in detail, while in others the depth is only estimated. Where the underlying data is not solid enough, we deliberately draw NO depth contour instead of drawing a line that could be wrong, and a tapped depth is marked as an estimate. We do not guarantee the accuracy, completeness or currency of this information. SUBSCRIPTION Piri Reis Premium is an auto-renewing subscription, available monthly or yearly.
