Navionics have announced the publication of new electronic charts in a format they are calling Navionics +. For details see
The charts are said to combine three elements of data:
--navigation data such as location of aids to navigation and spot sounding data
--bathymetric depth data with detailed contour lines, referred to by Navionics as SonarChart; and.
--crowd-sourced data about shore resources such as marinas, restaurants, accommodations, and so on, referred to by Navionics at Community Edits.

Sounds pretty cool. It looks like you get 50% off if you bought a navionics card after july 2010.
It seems like they are trying to do something similar to insight genesis with the crowd sourced data. Has anyone tried this?

I visited the Navionics website recently. There you can preview the new Navionics+ charts. I used the preview viewer to look at chart data for the area we were boating, near Northport in Grand Traverse Bay, Northern Lake Michigan.
I was very impressed with the Navionic+ chart for that area. There was a presentation of depth soundings with contour lines at one-foot intervals. This presentation of the hydrology of the area was the best I have ever seen.
Next, I scrolled the preview viewer into Georgian Bay, in order to see what the Navionics+ charts looked like for the Canadian Small Craft Route. Here I found a surprise. The preview viewer cannot show this data because the publisher, the Canadian Hydrographic Service, prohibits that use.
The preview viewer is a bit hard to find on the website. Here is a link to it:
Readers may find previewing the new Navionic+ charts with their web viewer will be an good way to see what sort of detail is available for your particular area in these new charts.

I visited the Navionics website to use their Navionics+ chart preview, this time looking at some remote areas of Lake Superior. Again I found the depth soundings presented in contour lines of one-foot interval. This was amazing detail for the depth soundings.

I went to Navionics' website and had a look at an area that
I'm very familiar with because I've done several hundred dives
there, because I've whalered over it a couple of hundred times
with my Humminbird six-beam SONAR, and because I've done
detailed bathymetry of it using GlobalMapper software and
the wonderful GIS data available from the Seafloor Mapping
Lab at Cal State Monterey Bay (guess where they practice).
First, you need to click on the sonar icon in the lower left
And they have the NE corner of Pt. Lobos State Natural
To their credit, they do include the new State Marine

The presentation with one-foot contour lines is nice. Now, whether or not the data is accurate, well, that's another topic.
