The most detailed nautical charts

Nautical charts are essential for marine enthusiasts and professionals worldwide. If you are looking for an accurate nautical chart with information about lakes and marine areas, a nautical chart will be your greatest ally. Use the map to study docking plans and safe contour areas, identify tides and currents, find help, services and much more!

SonarChart

The SonarChart feature offers a wealth of HD contour detail beneath your boat for marinas and lakes, helping you increase your knowledge of the area by easily finding shallow areas or fishing spots at any depth.

Community Edits

With the help of thousands of Boating APP users, all valuable local information, such as seasonal buoys, lights, rocks, anchorages, ramps and points of interest such as restaurants and stores, is constantly reviewed and enriched.

Dock-to-dock

All existing autorouting systems calculate a route from point A to point B only if both are in open water, but good guidance and planning are necessary in complex, narrow waterways with a maze of variables.

Navigate to your next point with the help of the Dock-to-Dock feature. This feature creates a suggested route for you, from an actual starting point to an actual endpoint, based on chart information and navigation aids.

SonarChart Live

Watch new maps with bathymetry and up to one inch of accuracy being created as your boat moves over the water! They appear as an additional layer over your map and are stored on your device for future use.

The SonarChart Live feature lets you explore and create maps of areas that have not yet been mapped, such as your favorite lake or reservoir.

Advanced chart options

Highlight shallow areas, whether to look for schools of fish or to indicate hazardous locations to avoid damage to your engine or hull; this option provides visual identification of shallow areas.

Contour density adjustment – Sometimes steep ledges can result in overlapping contour lines. Adjusting the density lets you see more clearly by reducing the SonarChart density level.

When you know schools of fish are suspended at certain depths, highlight the range so you can quickly identify more places to check.

Plotter synchronization

This feature lets you transfer routes, waypoints, update chart layers and much more from or to the Boating APP.
