Surprising response regard to maritime safety. While navigating, make sure you have activated the nautical charts. ' We also remind you that the layer Sonarchart is not suitable for a safe navigation, it is useful for locating fishing areas at any depth level. This is what expresses Navionics customer service to a user in response to an error report, I quote : The first being to navigation use and the second to fishing use. In Navionics Boating app, you can switch between the 'nautical' so-called chart and SonarChart. Navionics nautical charts and SonarCharts I agree more with these remarks that I already spoke in this direction in the past ( ¹). ' When we know how seriously the hydrographic survey by official services are performed (even if they are old) one can remain stunned for the fact that a regular boater, often unable to do a calculation of tide with twelfths rule, can transmit information affecting the safety of the ships to a provider of electronic charts. ' I find it absolutely incredible, or even criminal, Navionics alters its charts using soundings provided by users who are not really able to give absolutely accurate information. Otherwise, What credit make to data collected by Mariners fans ? As expressed by these users : It seems however that the reality is a little different, and that SonarChart have only actually collected interpolated details. Data collected in real-time during journeys are sensible feed a Community database for this purpose. Navionics has developed support of different sounders among the most used by boaters. These charts with the sole purpose to improve the marine recreational fisheries ground contours. The concern to maintain the application Navionics Boating (ex-Navionics Marine) in the first rank of the navigation for mobile apps has generated the bright idea of offering users to feed, by their own identified of soundings, bathymetric charts called SonarChart. The recent deterioration of charting quality is undoubtedly the consequence. Unfortunately, marketing orientation of Navionics to risky choices confirm the fears I expressed five years ago ( ¹).

So, What happens to Navionics ? I have promoted this charting, mainly for iNavX, I have it widely used and considered so far as being certainly the better designed and better update of private vector charts. ' Comparing, about Perros-Guirec, Navionics SonarChart updated a few days ago with the ordinary Navionics chart : Martian channels arise on the foreshore in front of the Harbour, and, Lo and behold, There are now two benches which discover before two pontoons, including mine (For those who do not know : the underwater quay that surrounds the port provides at least 2,5 m of water everywhere). ' I've done there is more than 6 months attempting to report to Navionics that many soundings contours in the small port of Burela in Galicia were completely crazy over the official charts and all other electronic charts soundings. Back in France, I am surprised to find out about new versions of the Navionics charts a channel around the island of Tatihou close to St-Vaast-la-Hougue. ' Back from Holland, I noticed many differences between actual soundings (corrected potential gap of tides) and values of the sounder. This forum is public, I extract some telling quotes, the authors will recognize : Some contributors of this forum were sent also to the service their findings. In the same time, several threads on the subject have been developed on the french forum Hisse-et-Ho or the sling is organized. He sent Navionics support email documented with screenshots of the many deficiencies noted during its summer sailing. The first to having informed me is Jochen Luhrs, the German translator of iNavX, with whom I recently collaborated in the writing of tutorial iNavX in this language.

The most important is that these findings are made by assiduous users of long-standing Navionics cartography, experienced navigators. A bit everywhere in Europe, Germany, Baltic countries, French coasts of the Channel and until Spain, appeared non-existent channels and erroneous soundings, missing soundings, missing information, contradictory bathymetric information depending on the zoom levels, and so on. Since the beginning of the navigation season, many boaters have found an increasing number of errors on Navionics charts, as a result of recent updates, all media.
