These new oeRNC Explorer charts
are better than the previous published, no longer available version from Fugawi
. The current
charts are edited to fit right into OpenCPNs way of quilting charts seamlessly without interfering borders.
The explorer charts have all the same information that is printed on the paper charts.
When planning a route
it's a good idea to look at the individual charts in single
chart mode. Why? Due to quilting some text may be hidden at certain scales.
With the Fugawi
charts we recommended users to primarily use the single
chart mode. With oeRNC the Explorer charts should be treated like all other raster charts.
Whenever Bahamas is discussed the question of which charts to use comes up.
The general conclusion on this forum is to recommend the Explorer Charts.
The nv-charts for Bahamas are still available for OpenCPN
if you are using windows. These charts are OK but not as detailed and updated as the Explorer Charts.
Some users are "enamored" with the CM93 charts. Don't even try to use them in the Bahamas, the geo-referencing, details and depth
are way out in many areas.
charts are known to be inaccurate in many areas, and are not reliable. This conclusion is also supported by numerous discussions on this forum.
There are also charts available that overlays Navionics
charts on sat pics. This may sort out the positions of islands etc, but not the depths.
iSailor has an app that uses their vector charts. I have used this quite a bit a few years back, when nothing much was available for OpenCPN.
Just today I compared iSailor and Explorer in a critical area - Bimini
. The channel in to North Bimini
keeps changing quite a lot. Explorer stays on top of the situation by issuing corrections for each edition, and in between, if necessary. iSailor sticks to old surveys, that, if strictly followed today would put you aground.
Here is Explorers latest update
The oeRNC chart is a bit dated in this area. Probably a year old.
Compare these to this screenshot that includes isailors latest update (20th of June 2019).
