The morning light slants low across the water as the glass-bottom boat eases away from Ko Olina’s marina — the lagoon reefs slipping past like pages in a field guide while the open ocean beyond promises a different kind of drama. Beneath your feet, the boat frames coral gardens and surgeonfish; above the surface, the winter migration brings humpback whales that punctuate the horizon with breaches and tail slaps that feel both sudden and deliberate.
