PIRI REIS PREMIUM

• Anchor Watch: drop a virtual anchor, set a safe radius - if your boat drifts, a loud alarm sounds, even with the screen off
• Offline charts: download the areas you sail, or the Sea Chart Pack - all world seas with depth shading plus the entire Mediterranean in detail
• Depth map: depth shading for every sea on Earth, labelled depth contours, and tap anywhere to read the depth in metres
• 3D seabed relief: shaded relief makes canyons, shelf edges and seamounts visible
• Sea marks: buoys, lights and beacons
• Rain radar
• Detailed marine weather on tap: wave height, direction and period, swell, currents, sea temperature, visibility and pressure

Safety features stay free. 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.
