You step off the dock at Perry Hotel Marina as the engine’s low thrum answers the Atlantic. The boat cuts a straight line west; the city’s clamor falls away and the Gulf widens until only sky and turquoise remain. After roughly 30 miles, the Marquesas Keys appear as a scatter of white beaches and mangrove shadows — islands that dare you to explore.
