Heikell is still having some sort of a monopoly on that subject. So if you are going to sail in that water, you could not avoid this book. There is simply nothing else! Despite the fact that it's professionally done with a lot of research and work behind it, I found it very limited on human insights. And if there are any, it tends to be all the same ("the port is very crowded - don't go there") comments. I still remember my Greece sailing experience (wonder who is the author of The Greek Water Pilot You bet, - Heikell) - if I would following Heikell suggestions we would never anchor in "extremely crowded" port of Hydra, and we would miss one of the most beautiful Greek islands, everybody still remember. Everything is crowded in Mediterranean. If it's bothers you, don't go there!
