Two Gulf of Cugnana marinas hold 1,239 combined berths south of the Consorzio Costa Smeralda. Marina di Porto Rotondo runs 650 berths for vessels up to 90 metres at 5.5-metre draft (web-verified). Marina di Portisco, the IGY-managed granite-built marina between Porto Rotondo and Porto Cervo, runs 589 berths up to 90 metres at 10-metre draft. The villa pool around the two marinas runs 78 properties in 2026 at peak-week rates of EUR 18,000 to EUR 96,000. The structural choice is between the walkable town-and-marina pattern of Porto Rotondo and the isolated marina anchor of Portisco. The piece names what each delivers and what the yacht-side tax actually costs.
By The Villas For Kings desk
The Costa Smeralda buyer who is yacht-first has three real choices on the coast. Inside the Consorzio, the Porto Cervo marina at the top of the rate card. South of the Consorzio, on the Gulf of Cugnana, the Porto Rotondo and Portisco marinas at the middle of the card. The 1,239-berth combined Cugnana capacity is the structural answer for the yacht week without the Porto Cervo rate premium, and the villa pools around the two marinas are the structural answer for the on-land base.
We have run the 2026 rate cards on 78 properties across the two marina-adjacent pools, walked the Porto Rotondo town and the Portisco perimeter across four years, and tracked the yacht-side villa product against the inland equivalent. The piece names the walk lines, the rate bands, the structural difference between the two marina experiences, and the listings we passed on this round.
Porto Rotondo is a planned marina town on the eastern arm of the Gulf of Cugnana, 14 kilometres north of Olbia and 16 kilometres south of Porto Cervo. The town was developed from the early 1960s by Luigi and Nicolò Donà dalle Rose on a model that paralleled the Aga Khan's Consorzio work to the north, with a planned piazzetta (the Piazza San Marco at the centre of the town), the Chiesa di San Lorenzo by Andrea Cascella, and the marina on the seaward side (web-verified through the Consorzio Porto Rotondo). The marina holds 650 berths for vessels up to 90 metres at 5.5-metre draft. The town footprint is small, walkable, and structurally separate from the open Costa Smeralda coast.
The villa pool inside the Porto Rotondo town and the immediate ridge holds around 46 properties in 2026 at peak-week rates of EUR 22,000 to EUR 96,000. The median is EUR 42,000. The architectural register splits into three bands: pre-1985 town-side villas with the Donà-Cascella vocabulary of stone, white plaster, and curved roof lines (EUR 22,000 to EUR 42,000), post-2000 contemporary builds on the ridge above the marina (EUR 42,000 to EUR 72,000), and a top tier on the Punta Volpe headland north of the town (EUR 72,000 to EUR 96,000). The walking-access pool inside an 18-minute arc of the Piazza San Marco runs around 22 properties at a 12-to-18 percent premium against the equivalent ridge property.
The structural feature of the Porto Rotondo week is the marina-town walk. The Piazza San Marco, the church, the marina restaurant line (including Country Bar, the Caffè Don Diego pattern at the marina edge, and the seasonal restaurants on the harbour), and the marina itself sit inside the same walking arc as the closer villa pool. The buyer who wants the marina visit, the harbour aperitivo, and the dinner pattern as a walking-distance default is the structural Porto Rotondo buyer. The drive lines to Olbia airport (14 km, 18 to 28 minutes) and to Porto Cervo (16 km, 18 to 28 minutes) are short.
Marina di Portisco sits on the western arm of the Gulf of Cugnana, roughly halfway between Porto Rotondo and Porto Cervo on the SP59. The marina is operated by IGY Marinas, built entirely of Sardinian granite, and runs 589 berths for vessels up to 90 metres at 10-metre draft (web-verified through IGY). The structural feature of Portisco against Porto Rotondo is the deeper draft, which accepts a larger superyacht. The structural feature against Porto Cervo is the lower berth fee and the easier shore-side access to Olbia airport. The trade-off is that Portisco is not a town; it is a marina with a small commercial frontage and a structurally isolated villa pool.
The villa pool around Portisco (the Cugnana ridge above the marina, the Punta Marana headland to the south, and the Marinella pocket on the inland approach) holds around 32 properties in 2026 at peak-week rates of EUR 18,000 to EUR 64,000. The median is EUR 32,000. The walkable-from-marina pool is small (around 8 properties), and the structural pattern is the villa-and-driver model, with the marina visit as a daytime anchor rather than a walk-out evening pattern.
The buyer brief that fits Portisco is the yacht-first buyer. The Cugnana ridge villa is the on-land base. The marina is the structural reason to be there. The yacht week (whether chartered through one of the principal Sardinian brokers or owned and berthed at Portisco for the season) is the centre of the rhythm. Dinner on the boat, dinner ashore at one of the Portisco harbour restaurants, or the drive into Porto Cervo for the YCCS pattern: all three are workable from the ridge.
The buyer brief that does not fit Portisco is the town-walking buyer who has read the headline rate band of EUR 18,000 to EUR 64,000 and assumed the Porto Rotondo experience at the Portisco price. The two are not the same product, and the buyer who books an inland Cugnana ridge villa expecting to walk to a piazzetta at dinner will be running the driver line every night.

The yacht-side tax is the rate-band premium that the Porto Rotondo and Portisco villa pools price against the inland Cugnana, San Pantaleo, and Telti equivalents. The structural test is to take a 2026 peak-week six-bedroom villa with sea view at three positions: walking-distance to the marina, ridge above the marina, and one valley back into Cugnana inland. The numbers in our 2026 sample run at EUR 56,000 for the walking-distance property, EUR 44,000 for the ridge, and EUR 32,000 for the inland equivalent. That is a 30-to-43 percent premium for the marina-adjacency layer.
The buyer who is yacht-first should pay the tax. The marina-adjacency is the structural reason to be on the coast, the tender drop and the on-land dinner pattern need the walking access, and the inland villa imposes a 22-to-38-minute driver line on every transfer to the boat. The cost of the driver line across a seven-day week with two transfers a day runs EUR 4,200 to EUR 6,600, which closes a meaningful share of the EUR 12,000-to-EUR 24,000 rate-band gap.
The buyer who is villa-first and yacht-never should not pay the tax. The inland Cugnana, San Pantaleo, and Telti pools deliver the on-land Sardinian week at structurally lower rates, with the marina visit as the day trip rather than the daily beat. The 2026 inland pool around San Pantaleo runs a similar architectural register to the Porto Rotondo ridge, often the same building era, and the rate-band saving is structural rather than a function of build quality.
The trap is the buyer who books the marina-adjacency at the premium without using the yacht. We see this pattern most often in the wedding-takeover brief and the family-reunion brief, where the marina-side aesthetic was sold as the structural feature but the week is actually a villa-based rhythm with no boat. In those briefs we consistently recommend dropping one ridge inland.
The first is a Porto Rotondo Punta Volpe seven-bedroom contemporary at EUR 86,000 a week, marketed as a "town-walkable estate with private marina jetty." The walk from the property to the Piazza San Marco runs 22 to 32 minutes downhill on the SP73, the return uphill in evening shoes runs 32 to 42, and the "private marina jetty" is a 9-metre tender pontoon on the property's small private cove that does not accept anything above 15-metre LOA. The property is otherwise a strong Punta Volpe estate, and we would book it at EUR 58,000 to EUR 64,000 with the walk reframed as a driver-line pattern and the jetty described accurately as tender-only.
The second is a Cugnana ridge five-bedroom inland villa at EUR 36,000 a week, marketed as "Marina di Portisco walking distance." The walk from the property to the marina gate runs 32 to 42 minutes one way along the inland road network with one 380-metre unmade section, and the structural pattern is the driver line. The "walking distance" claim is not accurate. We would book the property at EUR 24,000 to EUR 28,000 as a strong inland Cugnana ridge villa with the marina described as a 6-to-10-minute drive.
The third is a Marinella four-bedroom at EUR 22,000 a week, marketed as "Portisco-marina-adjacent for the yacht week." The property sits 1.8 kilometres south of the marina on the inland Punta Marana approach, and the marina drive runs 6 to 10 minutes. The marina-adjacent claim is materially true at the drive level and materially false at the walk level. The property is structurally a strong inland marina-week base and we would book it at the listed rate with the walk-to-marina expectation removed and the yacht-week brief framed as a driver-line pattern.
Book Porto Rotondo if the brief is the walkable marina-town rhythm, the Piazza San Marco evening pattern, and the EUR 22,000-to-EUR 96,000 rate band with the option to take the walking-distance premium for the closer pool. The Porto Rotondo buyer wants the on-land town as the structural feature of the week, the marina visit as a walk-out beat, and the closer airport drive. The yacht is the daytime anchor, not the structural reason to be on the coast.
Book Portisco if the brief is yacht-first, the inland villa as the on-land base, and the EUR 18,000-to-EUR 64,000 rate band that the marina-isolation pricing delivers. The Portisco buyer wants the marina because the boat is the centre of the week, accepts the driver-line pattern for the on-land transfers, and treats the villa as the place to come back to rather than the centre of the rhythm. The deeper draft of the marina accepts the larger superyacht, which is the structural feature.
Do not book Portisco for the town-walking brief. The marina has no town, the walkable villa pool is small, and the buyer who wants the Porto Rotondo experience at the Portisco price is structurally in the wrong place. Do not book Porto Rotondo for the maximum-superyacht brief; the 5.5-metre draft cap is structural and the boats above this draft are at Portisco or Porto Cervo. Do not pay the yacht-side tax if the yacht is not part of the week; the inland Cugnana, San Pantaleo, and Telti pools deliver the on-land Sardinian week at structurally lower rates.
