This chart display is an aid to situational awareness only — not for navigation. It is designed to facilitate the use of authorized government charts, not to replace them. Only official government charts and notices to mariners contain all of the information needed for safe navigation, and, as always, the captain is responsible for their prudent use.
Canadian waters are shown from the Canadian Hydrographic Service chart service as a picture rather than chart data: depths there cannot be clicked for a reading, and the safety-contour setting does not recolour them. Contains information licensed under the Open Government Licence – Canada.
Depths, buoy observations and positions shown here may be delayed, incomplete or inaccurate.
By continuing you acknowledge that XLOKK.COM and its operators accept no responsibility or liability for any accident, injury, loss or damage arising from the use of this site.
Vector chart built from NOAA ENC cells. Depth shading is computed in the browser from the charted shallowest depth, so changing the safety contour above is instant and does not reload any chart data.
