Kefalonia, Cephalonia… however you want to spell it, this Greek island is well-known for its natural beauty. The coastline is dotted with small bays, often harbouring golden sand beaches and crystal clear waters. Sounds like the perfect destination for relaxing, sunbathing, and doing nothing more active that the odd dip in the sea to cool down. It probably is. But I wanted something more exciting, something fun and challenging. So my trip was spent onboard a yacht with my partner, my parents and my brother. And we were the crew.
