Rod Heikell's guides are seen as the definitive guides to sailing (cruising) in Greek waters.
Ports, harbours and marinas are clearly and accurately described and the diagrams are clear and easy to follow. We sailed recently in Greece and along with the Imray chart, this guide formed all the information you are likely to need.
My one complaint is that co-ordinates are not given for the ports, harbours, marinas and other points of interest such as quiet anchorages and bays. To input these into the GPS meant going back to the chart, where it would have been so much easier to be able to lift them straight from the guide. Hopefully this will be fixed in later editions. Otherwise an essential guide to anyone wanting to cruise the waters around Greece.
