Salt spray and engine hum fade as you step off a small dive boat into warm Caribbean air; the water ahead is a deep, shifting green that invites you to breathe differently. On a certification day in St. Thomas an instructor’s calm voice guides you through checklist and skill drills, and the reef waits below—curious patches of coral and the hushed shapes of fish that inspect new divers like strangers at a marketplace.
