We spent 5 weeks in Sardinia last summer including 1 week hosting a 6
catamaran flotilla out of Portisco through Maddalena and Costa Smeralda. Several charter companies along the coast (Olbia, Cannigione, Portisco). Winds are variable so we had to change up our itinerary some. Pre-reserving berths a good idea if you're staying in
marinas. Lots of great restaurants, cute villages, beautiful beaches (though Sardinia is very protective of such). Happy to answer any questions about it. Blog forthcoming.
