Same atlas neighbourhood as Great Barrier Reef (places). Route, season or institution that sets access. Cross-checking field checklists against the comparison lab shows that metric 2 under “Yongala lost” for Great Barrier Reef never acts in isolation; it shifts alongside structural constraints and local standards.
Safe operating band — speed, depth, load or dose. Agency or type-approval gate before public use. Skill carry-over across domains; usually limited. Figures valid only inside a dated window. Country/language notes that must not stay English under a local URL. Prefer dated bands over current live figures. Rather than relying on simplified league tables or slogans, keeping the primary Great Barrier Reef section open beside benchmark 2 (“Yongala lost”) gives operators and readers a verifiable decision trail.

Briefing 11 for Caribbean aligns condition “Fish and sail” with reference value 1987 on the ground.
Caribbean: 1987 (2026)Risk mark {risk} means you stay inside {depth}, not past it.
Reading 12 of Caribbean uses “Cozumel and Cayman clubs” and figure 1987 as a checkable baseline.

5-Step Execution & Verification Playbook
- Read the skill mark — Skill ceiling on this hub is {skill}/100 — editorial teaching, not a skills test score.
- Read the risk mark — Risk is {risk}/100 here. It compares topics in the atlas; it is not a live hazard bulletin.
- Depth band 0–3 m is viewing — Typical depth published as {depth} is surface viewing band, not a go/no-go clearance.
- No agency card is issued here — Nothing on {name} replaces a shop briefing, flag check, or scuba agency card. Close if you need certification advice.
- Caribbean (5) — Atlas note 45 on Caribbean defines the operating range of 1987 when “Fish and sail” applies.
Myth vs. Evidence Fact-Check
Are the skill, risk, and depth marks a dive clearance?
No. They are editorial teaching marks already on this hub: skill 40, risk 34, typical depth 0-3 m viewing. The envelope pins last versus this reading. It is not a shop briefing or a safe-today stamp.
What does the 0-3 m viewing band decide?
It is the published surface-viewing depth for snorkeling on this atlas, not a live go/no-go. Current, boats, and park flags sit in the safety chapter.
Do I need a scuba agency card to snorkel?
This hub's quick facts say none required. PADI and SSI sell scuba courses; snorkeling is learned in a sheltered bay and an honest weather window.
What is last versus this envelope for?
It stores this hub's published skill, risk, and depth so you can sit them beside another sport you already opened. Compare marks. Do not treat the pair as clearance.
