Ken, I also recently got the Italian Waters pilot by Heikell (9th Edition) but for the Adriatic
it only goes up as far as Brindisi and does not cover anything further north on the E coast. I met Lu Heikell at a recent CA meeting in London but unfortunately Rod was sick in bed
. I have always used their Pilot books
for many years and the only one i had with me at the time was a 1998 Edition of their Greek Waters Pilot which she kindly signed for me.
For the Croatian side of the Adriatic
you need the 777 but i guess you got a copy of that already. The Imray Adriatic Pilot (by T&D Thompson not by Rod Heikell) will cover both E coast of Italy
and Croatia but think 777 is best for Croatia. I have used it extensively and found the 777 excellent.
