The boat slips quietly away from the marina and the shoreline melts into a ribbon of white sand. Sunlight slices the surface; below, the reef waits—stony ridges and garden-like coral heads that dare you to look closer. After pool drills and equipment checks at the El Cid marina dive shop, novices find certainty in a regulator’s steady hiss and the slow, patient choreography of a guided descent.
