A low-slung catamaran eases out of Heraklion harbor and the city’s heat peels away. Salted wind pushes the boat north; the Aegean opens into a clear, blue stage and Dia Island sits like a weather-polished rock ahead. Guests spread across cushioned decks, the crew checks lines, and the day becomes a rhythm of swim, snorkel, and sun.
