Reef etiquette in 1980: Park paper

The rulebook that sits under every snorkel and dive — no standing, no chasing, no souvenirs, and why parks now say it in five languages. Reef etiquette is the shared conduct layer for snorkeling, scuba and freediving on living coral and in seagrass. It is written by parks, customary owners and a few national statutes — not by a training agency’s marketing slide.

The skill ceiling is low on purpose: the rules are simple and the failures are expensive in centuries of coral growth. Accessibility is high because anyone who can enter the water can also choose not to kneel on a colony. This chapter is not a live briefing and not a permit. Local rangers, mooring fees and seasonal closures override any atlas sentence.

Reef etiquette and local marine parks set where fins may go. Coastguard flags and shop briefings beat blog visibility claims. Charter fleets and shore entries differ by bay — ask the desk that day. Reef etiquette mapped for mechanisms, locale notes and limits. Reef etiquette sits in the snorkel atlas — mechanisms, locale notes and limits, not slogans.
