After spending the winter in Menorca in Paul and Sheryl prepare their sailboat, "Two-Step", for another season of exploring the Mediterranean. It's hard to say goodbye but, ready for new adventures, they cast off their docklines and head to sea for a 2-day passage to the Italian island of Sardinia. En route they encounter vast flotillas of neon blue jellyfish that travel the sea using tiny sails. Late the next day, the Shards make landfall at the dramatic headland of Capo Caccia where they explore an enormous cave before sailing to the medieval town of Alghero.
