When the marina slips its ropes and the city grid of Naples blurs into a wide horizon, the morning opens like a dare. The water pushes forward, inviting and restless, and within minutes the shoreline of South Florida becomes a flicker of palms and mangrove teeth. Captain Tim — a U.S.C.G.-certified guide with three decades on these waters — trims the engine and reads the tide the way a mountain guide reads a ridge: by feel and habit. You feel the boat settle into a channel, the Ten Thousand Islands spreading like a complex of inked islands across a pale sky, and the fishing begins.
