The boat's easy:
(1) Boats are usually on the water
(2) The water is at the edge of the town
(3) The boat leaves from the Old Harbour, which is sensibly placed next to the water
(4) The Old Harbour is next to the Old Fort
(5) The Old Fort is a stonking great rock with a castle on the top
(6) Useful phrases (a) - "Where is the sea, parakalo?"
(7) Useful phrases (b) - "Is that gigantic rock with a castle on the top The Old Fort?"
(8.) If you are at the edge of the sea and the Old Fort is to your right walk past it
(9) Go down the steps to the harbour level
(10) The boat should be floating in the water. If it has sunk, ask for your money back
(11 ) More useful phrases: "I've lost my husband - fancy a drink big boy?"
(12) Notes: Water is the blue wet stuff that laps on the shores of Kerkyra
(13) Notes: Water is also the blue wet stuff you can jump into off the boat on the way home
(14) More useful phrases: "Yassou, Captain. My husband jumped off the boat and he's swimming to the shore. Can we leave now?"
(15a) Addition notes: If you don't know which way the sea is, ask: "Poo eenay ee thalassa?"
(16b) Additional notes: It is not essential and possibly risky to to take a husband on trips. They'd be happier in the bar
Have fun!
