Posidonia Anchoring Fines in Italy: How to Spot Seagrass and Anchor Legally (2026)
Real fine amounts, how summer patrols catch crews, and how to read seagrass from a catamaran’s raised helm so you anchor on sand and stay legal in Italy.

You do not need a superyacht to do the Costa Smeralda. A catamaran on the hook off the right bay puts you closer to the action than half the people paying four figures a night for a Porto Cervo berth — and you wake up swimming instead of stuck on a pontoon.
The trick to a Costa Smeralda boat party week is geography. The beach clubs, the dinner spots and the late-night scene all cluster within a few miles of each other along the Gallura coast and the islands just offshore. Anchor smart, run the tender in for dinner, and you get the glamour without the marina bill. Here is how the scene actually works from your own boat in August.

Let’s be honest about why this matters. A night alongside in Porto Cervo’s Marina dell’Aga Khan in peak August can run from several hundred euros for a modest cat to well over a thousand for anything large, and that is before you have bought a drink. Portisco and Porto Rotondo are a touch friendlier but still steep in season.
Anchoring offshore costs nothing. Drop the hook in one of the sheltered bays, splash the tender, and you spend your money on the experience rather than the parking. Most crews find the only times they actually take a berth are for a midweek reprovision or when a hard mistral makes the anchorages untenable. The rest of the week, you live at anchor and visit the glamour on day passes.
The signature move on this coast is the beach club you reach by tender, not by road. Phi Beach at Forte Cappellini near Baja Sardinia is the famous one — built into the granite below an old fort, with a sunset DJ set that draws boats from all over the gulf. You anchor off, tender in, and the aperitivo-into-night transition happens right there over the water.
Further round, the clubs and lidos along Liscia di Vacca and the beaches near Cala Granu and Romazzino let you do the same thing on a smaller scale. The pattern is consistent: a sand or granite cove with a club tucked into it, a line of tenders nosed onto the beach, and a crowd that arrived by water. Anchor outside the swim zone, keep your speed to nothing on the approach, and you are part of the scene by mid-afternoon.

If you want to watch the spectacle, two areas deliver. The waters off Cala di Volpe fill with large yachts through August, drawn by the Hotel Cala di Volpe and its famous pool-bar scene — tender reservations there are a thing, and the people-watching from your cockpit is free. The other magnet is the stretch between Porto Cervo’s old port and the islands, where the biggest boats anchor in the deeper water and shuttle guests ashore.
From a catamaran you sit at the edge of all this comfortably. Pick a holding spot on sand outside the superyacht cluster, and you get the floor show without the fuel bill. Sunset over Porto Cervo from your own foredeck, with the lit-up motoryachts as a backdrop, is the version of the Costa Smeralda most people pay a fortune to be inside.
Reservations are the currency here. The Porto Cervo old port has a row of restaurants and bars around the Piazzetta and the marina — drinks at the waterfront spots, then dinner at one of the trattorie up the lanes for something less eye-watering. Book ahead in August; walk-ins are tough.
For the food worth crossing the gulf for, head to the simpler ports. The fish places in Cannigione and around Porto Rotondo serve the local catch without the Cervo markup, and Sardinian classics — fregola with clams, bottarga grated over spaghetti, suckling pig if you are inland — are the real reward. Tender logistics are the only thing to plan: know where the dinghy dock is, agree a pickup time, and carry a decent torch for the run back to the boat in the dark.

Your home anchorages shape the whole week. A few stand out.
Close to Phi Beach and well sheltered from the southerlies, this is the natural base for the nightlife end of the trip. Good holding on sand, an easy tender run to the clubs, and a short hop to the La Maddalena islands when you want a quieter day.
Just off the coast between Porto Cervo and Porto Rotondo, these granite islets give you that famous Caribbean-blue water with anchorages that empty out at night. Spend the day here on the hook, then run in for dinner — it is the best of both worlds, glamour by night and near-solitude by day.
For the superyacht spectacle and the hotel scene, anchor in or near the bay itself. Busier and more exposed, but unbeatable for atmosphere on a calm night.
Wind is the variable that breaks plans here. The mistral can pipe up hard from the northwest with little notice, and several of the party anchorages are exposed to it. Keep an eye on the forecast, and have Portisco or a sheltered cove in your back pocket as a bolt-hole. Our wider guide to Sardinia’s best bays, islands and towns maps the sheltered alternatives, and the seven-day sailing itinerary around Olbia shows how to thread the party coast into a full week.

A sensible rhythm: start from the Olbia or Portisco bases, work north toward Porto Rotondo and Cala di Volpe for the first taste of the scene, then settle into Baja Sardinia for the club nights and use the offshore islets for quiet days. End back toward the base with a final night on the hook somewhere calm.
If your route runs further north into the protected archipelago, the 2026 changes in our La Maddalena permit and overnight anchoring guide matter, because the rules there are tighter than the open Costa Smeralda coast. Mix the glamour days with the wild granite coves and you get the full range of what northern Sardinia does best.
Yes — that is the whole appeal of doing it by catamaran. Anchor off the bays near the clubs, run the tender in for dinner and drinks, and you skip the four-figure peak-season marina fees entirely. Most crews only take a berth for the odd reprovision or when the mistral blows.
Phi Beach at Forte Cappellini near Baja Sardinia is the classic anchor-off club, with a sunset DJ scene built into the granite. The lidos around Liscia di Vacca and Cala Granu work the same way. Anchor outside the swim zone and tender straight to the beach.
Cala di Volpe, by the famous hotel, and the deeper water off Porto Cervo’s old port. Anchor a catamaran on sand at the edge of the cluster and you get the spectacle from your own cockpit without any of the cost.
Absolutely. The Porto Cervo Piazzetta spots and the better fish restaurants book out in peak season. Reserve ahead, plan your tender dock and pickup time, and carry a torch for the dark run back to the boat.
Mostly settled in August, but the mistral can blow hard from the northwest with little warning, and several party anchorages are exposed to it. Watch the forecast and keep a sheltered cove or the Portisco marina as a bolt-hole.
