The Bonifacio Strait is roughly 7 nautical miles wide and the two islands on either side run different charter weeks. Corsica is French, mountainous, sparsely marina'd, and roughly 40 percent less crowded by yacht count in August than the Costa Smeralda. Sardinia is Italian, broader, served by the most expensive marina cluster in the western Mediterranean (Porto Cervo, Porto Rotondo, Cala di Volpe), and built for the 70m-plus fleet. We have run both islands in 2024 and 2025, and the question we get most often from clients with a one-week charter window and a 50m to 65m yacht is the same one: which one. The answer is not symmetric.
Below is the version we give clients after the third call. The data points are 2025 season except where noted.
What each island actually is
Corsica is 183 km long and 83 km wide at its widest, with a high spine of mountains running north to south, and a coast that is mostly cliff, granite, and short white-sand pockets. The French départements of Haute-Corse (north) and Corse-du-Sud (south) divide it. The four yacht-relevant ports are Calvi (north-west), Saint-Florent (north), Ajaccio (south-west), and Porto-Vecchio with Bonifacio (south). Anchorages on the west coast (Girolata, Scandola, Piana) are visually the dramatic ones. The eastern coast is flatter and less worth the route unless transiting south.
Sardinia is 270 km long, 145 km wide, and runs the same north-south spine pattern. The yacht charter market concentrates on the 50 km of the north-east coast from Olbia up to Santa Teresa di Gallura. This corridor is the Costa Smeralda, the Aga Khan's 1960s development project, and now home to Porto Cervo, Porto Rotondo, Cala di Volpe, Romazzino, and the buoy-field anchorages off the La Maddalena archipelago. Outside this corridor, the rest of Sardinia is meaningfully less yacht-trafficked, with Alghero on the north-west, Cagliari at the south, and the south-east coast around Villasimius. The Costa Smeralda is what brokers default to. The rest of Sardinia is rarely on the proposal PDF.
Density and the August reality
In August 2025, the Costa Smeralda corridor between Cala di Volpe and Spargi (the central La Maddalena anchorage) carried a daily 24m-plus yacht count comfortably above 400. Porto Cervo's marina and the buoy field at Cala di Volpe filled by late July. Anchorage at the most-photographed La Maddalena spots (Cala Corsara on Spargi, Cala Coticcio on Caprera, Cala Granara) routinely held 25 to 50 yachts per day in mid-August.
The same August window on the Corsican west coast from Calvi south through Girolata, Scandola, and Cargèse averaged a daily count well under 200 yachts of 24m-plus. The Scandola reserve restricts anchoring entirely. Girolata's small bay caps practical anchor positions at roughly 12 to 18 yachts in the 30m-plus class.
That density delta is the headline difference between the two weeks. Sardinia delivers the Saint-Tropez-meets-Capri scene with a price tag. Corsica delivers a quieter week and a more rugged shoreline, at the cost of nightlife and the Porto Cervo dinner economy.
Yacht size compatibility
Sardinia is built for the 60m to 90m class. The Costa Smeralda marinas berth 80m yachts routinely and the largest slips at Porto Cervo will take 100m on advance booking. The La Maddalena anchorages will hold a 90m at the outer positions but the most photographed inner anchorages at Spargi and Budelli are tighter for anything over 60m.
Corsica is built for the 30m to 60m class. Calvi and Saint-Florent take up to roughly 65m at the visitor pontoon. Bonifacio's famous fjord-style entry will berth larger yachts (the inner port has accommodated 80m+), but the natural anchorages around the west coast, the Lavezzi islands, and Cap Corse are sized for 50m down. A 70m on the Corsican west coast spends most of the week at anchor in deeper water with longer tender runs.
If your yacht is 70m-plus, the Sardinia week is the more comfortable fit. If your yacht is 40m to 60m and the brief is "less crowded, fewer people on shore", Corsica wins.
Costs in 2026
Charter base rates are equivalent for the same yacht regardless of island. Where the two diverge is on dockage and the shore economy.
Porto Cervo marina nightly rates in August 2025 ran roughly €4,500 to €6,500 for a 50m yacht. Cala di Volpe buoy field, where most clients want to be for the social scene, ran €1,200 to €2,000 per night for the same size. Dinner ashore at Cala di Volpe or Phi Beach was a per-head number consistent with Saint-Tropez peak.
Calvi or Bonifacio dockage in August 2025 for the same 50m yacht ran €1,500 to €2,800 per night. Most of the Corsican week is anchored anyway, so the dockage line is smaller. The shore economy is meaningfully cheaper than the Costa Smeralda.
Fuel: a Corsica week typically covers 120 to 180 nautical miles depending on whether you do the west coast or both coasts. A Sardinia Costa Smeralda week covers 80 to 130 nautical miles. The Sardinia week burns less fuel. The combination of higher dockage and lower fuel on Sardinia versus lower dockage and higher fuel on Corsica nets out to roughly 10 to 15 percent more total cost for the Sardinia week on a 50m to 60m yacht.
The one-way option
The right way to run both islands in one week is one-way, embarking either Ajaccio or Calvi and disembarking Olbia, Porto Cervo, or Cagliari. The Bonifacio Strait crossing is 7 to 10 nautical miles depending on the line. The Lavezzi islands off the Corsican side and La Maddalena off the Sardinian side make day stops on each side of the strait the natural pivot.
A standard one-way: Day 1 Calvi embarkation, Day 2 Girolata and Scandola, Day 3 Cargèse and Piana, Day 4 Bonifacio and Lavezzi, Day 5 Cala Corsara on Spargi (La Maddalena), Day 6 Cala di Volpe and dinner at Phi Beach, Day 7 Porto Cervo disembarkation.
The one-way charter premium is the standard 5 to 10 percent on most contracts plus a manager-side reposition cost which is sometimes absorbed. We pay it because the route is the right route. The round-trip Corsica week is good. The round-trip Costa Smeralda week is also good. The one-way is better than either if you have the budget headroom.
What we would pass on
We would pass on the Costa Smeralda corridor for a charter client who has already done Saint-Tropez and wanted "less of the same". August Costa Smeralda is structurally the same scene with Italian language and Aga Khan architecture. It is the next stop on the same circuit, not a different week.
We would pass on the Corsican east coast (Bastia, Solenzara) for a chartering week. The west coast and the south are the photogenic Corsica. The east coast is the agricultural and ferry-port side.
We would pass on July 25 through August 20 for the Costa Smeralda if anchorage privacy matters. Cala Coticcio and Cala Corsara become roped-line tender-traffic spots. Move the dates to early July or after August 25 if the budget allows.
We would pass on captains who have done only the Costa Smeralda and "will do Corsica too". The Corsican west coast pilotage (Scandola reserve rules, the Piana inlet, the Calvi citadel approach) is its own brief. The Bonifacio Strait has wind funnelling characteristics that show up on the chart but feel different on the bridge.
Three things we would change about the standard pitch
Most brokers will pitch Sardinia first because the Costa Smeralda fleet is what is on their books and on their proposal slides. Push back if the brief was "less crowded". The right answer is Corsica with two days in northern Sardinia, not the reverse.
Push the broker to commit to specific La Maddalena anchorage positions, not "we will see on the day". The buoy field at Porto Madonna (Spargi) and the buoyed anchorage at Cala Coticcio (Caprera) require pre-booking through the park authority. The captain may handle this, but the booking is a fact, not a vibe, and it is worth verifying.
Push the broker on the Lavezzi day. The Cala Lazarina anchorage on the south side of Lavezzi is one of the better daytime stops in the western Mediterranean and is on the route. Some captains skip Lavezzi in favor of running straight to Spargi to make the Cala di Volpe dinner reservation. The Lavezzi stop is the better one.
The honest verdict
For a 40m to 65m yacht and a brief that says "fewer people, more rugged", Corsica wins. For a 70m-plus yacht and a brief that says "the Saint-Tropez scene plus rough granite anchorages", the Costa Smeralda wins. For a client with budget headroom and a 50m to 65m yacht in the middle, the one-way Calvi-to-Porto-Cervo week is the right answer and is the route we will pitch every time.
If the client is choosing Sardinia on the basis of the Cala di Volpe restaurant scene specifically, the answer is yes. If the client is choosing Sardinia because "Costa Smeralda is the famous one", that is the bad reason and Corsica is the better week.
FAQ
Which is quieter in August, Corsica or Sardinia? The Corsican west coast and the southern tip below Porto-Vecchio are roughly 40 percent less dense than the Costa Smeralda corridor in August. Sardinia's Costa Smeralda from Porto Cervo to La Maddalena is the most yacht-trafficked stretch in the western Mediterranean after Saint-Tropez.
Can a 70m yacht do both islands in one week? Yes, but only as a one-way charter starting Ajaccio or Calvi and ending Olbia or Porto Cervo, or the reverse. A round-trip from either island in seven days truncates the experience. The Bonifacio Strait crossing is a 7 to 10 nautical mile transit between southern Corsica and northern Sardinia.
What does a Corsica or Sardinia week cost in 2026? Base rates are equivalent to a French Riviera or Amalfi week for the same yacht size. APA runs 30 to 35 percent. Dockage in the Costa Smeralda corridor is the most expensive in Sardinia and roughly two to three times the Corsican equivalent. Fuel and dockage push the Sardinia week roughly 10 to 15 percent higher than Corsica for the same yacht.
Is Bonifacio worth the stop? Yes. Bonifacio's limestone-cliff harbor is one of the more visually distinct ports in the Mediterranean. Berth booking is essential in August and the inner port takes yachts up to roughly 80m at the inner quay.
Can the captain skip the Sardinia visit on a Corsica charter? Yes. A pure Corsica round trip from Calvi or Ajaccio works as a stand-alone week. The Sardinia detour is optional, not mandatory.
