I have been using Navionics charts
extensively on MacENC but am now migrating to OpenCPN
Next season I will be cruising only on the UK south coast, West Country and France
and Channel Islands. So I have purchased the oeSENC charts
for British Isles and France
Atlantic. There are various 'holes' in coverage as mentioned on the o-charts web site. I have already found other areas where detail is inadequate for navigation
, such as Christchurch, Dorset, the Swinge channel near Alderney. No doubt there are others.
What do other users recommend as an alternative or for infilling? o-charts suggest buying
S-63 charts but it is hard to find what I need without the ChartWorld Graphical Chart Selection tool and I am Mac only so cannot install it. The Navionics
S-63 charts on ChartWorld are expensive.
Having detailed charts available for places one might end up diverting to as a refuge - not just planned ports
- is looking very expensive.
