The boat slips away from the Honokohau Small Boat Harbor and the shorelights thin into a low, golden smear. Out here the ocean takes over—cool air, the thud of an outboard, and a single bright LED board casting a pancake of light into the black. That rectangle of illumination pulls plankton like a magnet, and as the raft of tiny organisms gathers, the sea answers: long-winged manta rays begin to appear, gliding into the light with slow, deliberate turns.
