The oeSENC charts are based on official vector-charts. The lack of interest in areas of certain interest to cruisers is obvious in this chart set. For example.... no coverage of Young Island Cut in St Vincent, nor of North Sound in Antigua
If you're thinking about the Easter Caribbean - Lesser Antilles- in particular, I recommend the newly released oeRNC set of charts from Imray instead. These raster-charts are electronic versions of the well-known Imray-Iolaire paper-charts that has been used for a long time.
As for Navionics
.......I have no direct experience of their EC charts, but have seen enough of that outfit not to spend any money
on their products.
