The outboard hum lowers and the skyline of Huatulco opens: low green ridges giving way to pearly bays, and a scattering of reef teeth visible where the water light breaks. Guests board Stenella—a 2022 deep‑V, purpose‑built ocean boat—its canvas roof throwing shade over cushioned benches. A marine biologist checks the underwater microphone while the captain eases the bow offshore; within minutes, the coastline recedes and the ocean starts to show its moods.
