The catamaran slips past the marina, engines low and the city dropping away — Waikiki’s high-rises shrink, Diamond Head’s rim holds steady, and the Pacific opens up like a blue room with a view. In winter months the water bristles with life; humpback whales roll and blast along Oʻahu’s southern shelf while spinner dolphins slice the sunlit surface.
