And doīnt forget the free and easy way to construct your own navigable .kap charts
using Paulīs great Google Earth
conversion program GE2KAP. VERY useful in close up areas where you do not have any charts
OK,they do not include soundings or sea markers but you get a good idea from the details of the map where also shallow water
and rocks usually are visible.
views are updated at fairly regular intervals as can be seen from the date at the bottom of the display.
See attached combination of GE and CM93 and the GE only detailed chart.
