The Maddalena archipelago just north of Portisco is a national park, and its water is so clear that boats are forbidden from dropping anchor in many coves — you pick up a mooring buoy instead. Which means the silence you get there is not luck. It is the law.

The Costa Smeralda was essentially invented in the 1960s by an Aga Khan with a taste for empty coastline — he bought the land, kept the buildings low and pink, and banned anything that ruined the view. Sixty years later it still works, which is why your anchorage looks like a postcard and not a car park.

Sardinia’s north-east wind, the maestrale, is famous for how hard it can blow — but it also clears the air and flattens the sea the next morning. Local captains plan around it. Ask yours to sail the sheltered side of the islands on windy days and you will get glassy water while everyone else hides in harbour.

A catamaran does not heel, does not roll and does not rush. Your morning coffee stays in the cup, your guests stay in a good mood, and the skipper gets to look like the calmest person in the Tyrrhenian Sea. That is not marketing — it is basic physics, and you get to enjoy it for seven days.
