Night on Vieques arrives as a slow, humid curtain; the reef-line breathes, the mangroves lean close, and the water begins to answer every stroke with light. You sit in a transparent kayak and push off from the rocky shore across from Sun Bay Beach, and the paddles split the black like a pen drawing phosphorescent script. Small fish flare like thrown matches; each ripple is a brief constellation.
