During my many sailing trips along the Croatian coast on a charter boat, concession buoys became a regular part of the routine. Today, many of Croatia’s bays are under concession, which means you can’t just drop anchor wherever you want—you’re required to use the available buoys, and yes, you have to pay for them.
If you tie your boat to a buoy, the overnight fee is usually around 2 to 4 EUR per meter of boat length. If you anchor without using a buoy but remain within the concession area, the fee is typically 50% less—but the concession holder still has the right to charge for anchoring.
To be honest, the biggest issue with buoys is that concession holders often place them too close together, without much thought for how different boats behave. In calm weather, things look fine—but when a gusty bora kicks in, which isn’t uncommon on the Adriatic, boats start reacting differently. Bigger ones turn slower, smaller ones faster; tall versus low boats behave in opposite ways… and if someone left too long a line, it's easy for boats to bump into each other—usually at night when no one’s watching.
That’s why some concession holders have introduced a system where you tie the bow to the buoy and secure the stern to the shore. This setup prevents boats from swinging and greatly reduces the risk of collisions. Plus, more boats can fit into a bay this way—anchored like in a marina, but with more space and privacy.
If someone approaches you to collect payment for using a buoy or anchoring, remember: they are obligated to show you a valid concession permit. That document must clearly state the area covered, the expiration date, and the maximum allowed fee.
As always in Croatia—if you know your rights and respect the rules, using a buoy can be a convenient, pleasant, and well-integrated part of your planned holiday on a rented boat.
