We sail in Croatia
every year in September. You need an ICC
. In the U.S.A. only US Sail and ASA
can issue these. You also need a VHF
which you can get on line from the FCC website.
As far as an earlier question regarding the winds is concerned, usually, in September, it is quite calm in the morning and it picks up in the late morning and afternoon. If anyone is interested in flotilla sailing, let me know. We organize them every year. Croatia
is one of the most fun places to go sailing.
