You step off the Haleiwa Harbor boat ramp and the north shore wind bites at your hair—salt and surf moving through the hull as the skipper motors past reef edges where the sea darkens and life gathers. The boat hums with briefing chatter: marine biologists outline safety, currents, and species identification while the ocean ahead tests the morning light.
