  "answer": "A classic 7-day sailing itinerary in the Balearic Islands around Ibiza and Formentera starts and ends in Ibiza Town and goes Ibiza Town → Formentera (Ses Illetes) → Espalmador → Cala d'Hort (Es Vedrà) → Sant Antoni → Portinatx → Ibiza Town: 6 legs and about 58 nautical miles in straight lines between the stops (our calculation; you will sail further). By our rules the best months for it are September and October, when the mean wind at Ibiza Town is 8–9 knots (our calculation from NASA POWER data); the Balearic Posidonia decree bans anchoring on Posidonia seagrass, so anchor on sand or use a buoy.",
