⚠ Navigate with care
AudioChart is an aid to navigation. Use it alongside official NOAA charts, your own navigation equipment, and good seamanship — not instead of them.
Chart data, depths, hazards, tides and buoys may be incomplete, out of date, or wrong.
AutoRoute suggestions can pass close to hazards, or miss them. Always check a route against official charts and what you see on the water.
GPS position and spoken bearings can be inaccurate or unavailable.
You alone are responsible for the safe navigation of your vessel.
AudioChart is provided “as is”, without warranty of any kind, and its authors accept no liability for any loss, damage or injury arising from its use. See the privacy policy.
