Now my personal favorite would be option 3. Let me explain myself. If we get away early from Lakka and we sail around the North Western Coast of Paxos, visit the caves and the set sail for the Southern Coast of the Island of Corfu we would have to sail around 35km for the day, lets say about 4 hours. We could then linger at a lot of spots and still moor for the night in the harbour of Lefkimmi. Then it is a short walk to the town for supper and provisions for the next day to Corfu. This would probably mean that we would have to make breakfast on the yacht on day 6 before we do the trip to Corfu.

So the day could look something like this

Spots we could visit would be something like this
