ILO/IMO Code of practice on security in ports
There is a new international ILO/IMO Code of practice on security in ports to be in effect from July 1st (international anti terrorist measures). This means that each port in the world must make an assessment of its port security and establish a port security plan. This plan must be validated by the relevant authorities in the country. The ultimate consequence may be the closing down of the port until the security plan can be accepted.
This will among other things imply restricting access to the port and particularly to the wharfs and docks - many of them freely accessible today. In my hometown Stockholm the quays are now being fenced in and guards check ID papers and clearance for those wanting to approach the ships.
I don't know to what extent this could affect places like IYCA - yacht clubs may have to maintain their own security level being private territories. But ports like Monaco, Cannes, Cap Ferrat and Cap d'Ail may be affected as most certainly all traditional commercial ports, cruise ship terminals etc around the world where the larger and larger yachts (Octopus etc) already now have to be docked.
Perhaps yachtspotters regularly visiting relevant ports could report if there are signs of fences being installed, guards etc restricting the possibilities for yachtspotters to approach the yachts.
