The yacht slides out of the marina with a soft mechanical breath and the harbor falls away — restaurants and palm-fringed boardwalks shrinking to a watercolor backdrop. Offshore, the Sea of Cortez lays out in sheets of turquoise while the arch at Land's End rises like an ancient doorway where currents dare to cross between ocean basins. Onboard, the conversation loosens; cameras come up. The captain points toward the unmistakable silhouette of El Arco, the Finger of Neptune and the curious Scooby Doo Rock as pelicans wheel and sea lions sun themselves on nearby outcrops.
