The cruise’s sunrise yoga classes are hosted on the upper deck by a man called Gaspare: Italian, of indeterminate age, and the lucky owner of a full head of thick grey-streaked curls tied back in a sexy little man-bun. He guides the class through several easy poses for beginners and those on the more rusty side, like Draco; it’s a miracle he can still touch his toes and balance on one foot without tipping off the edge of the boat.
