  "question": "What is a good 7-day sailing itinerary in Greece in the Ionian, from Lefkada?",
  "answer": "A classic 7-day sailing itinerary in Greece in the Ionian, from Lefkada starts and ends in Lefkada and goes Lefkada → Meganisi → Kalamos → Kastos → Ithaca (Kioni) → Kefalonia (Fiskardo) → Lefkada: 6 legs and about 61 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 Lefkada is 6 knots (our calculation from NASA POWER data); we could not verify any official mooring or quay fee on this route, so ask your base what to budget.",
