We found ourselves on board an old fashioned boat under full sail, wooden deck, slightly tarry ropes and the salty sea breeze in our nostrils as we were received a lesson on celestial navigation using a marine sextant. As the sea got calmer we relaxed in a hammock chair and got served a Hemingway Daiquiri, of white rum, fresh grapefruit and lime juice, Maraschino liqueur and syrup.
