Yes ,,, though typically Greek, they are not entirely sure how it will be enforced or when.
It applies only over 7m (so as the owner of a poverty model I am exempt) You have always needed a Greek translation of your insurance certificate and these are provided foc by your insurer. I also have a mock up in Greek of the ICC ,, again free from the RYA website just in case. The beauty of quiet places like Paxos is that no one cares or bothers you. No mooring fees, launching costs or harbour dues. This was the first year in 8 where the local port police/coastguard came alongside as we surfaced from a dive. Just asked if we were qualified divers and reminding me that fishing and diving on anti Paxos was not allowed. I confirmed yes and we knew and off they went. Being polite always helps ,,, and no need to draw their pistols !!
