Open-water swimming in 1896: Olympic swimming in the sea — Section 636: Olympic swimming in the sea
Reading 636 of Open-water swimming uses “Olympic swimming in the sea” and figure 10 as a checkable baseline. open-water-swimming · beat 1 · Continuous 1,500–3,000 m with bilateral breathing is the usual indoor prerequisite. Keep Open-water swimming with “Olympic swimming in the sea” and 10 from 1896. Panic in chop is harder to fix than a slow 100 m split.
Lakes, rivers and seas without a wall — sighting, temperature and the difference between a lido and a 10 km World Aquatics race. Open-water swimming is any continuous swim where the “pool” is a coastline, lake or river. It includes casual wild swims, organised 1–5 km events, and the 10 km Olympic marathon introduced at Beijing 2008.
World Aquatics and national federations write race rules on wetsuits, feeding and water temperature. Those rules do not govern a Tuesday lake dip — local clubs, coastguard advice and park bylaws do. This chapter is a map of practice and history, not a live swim plan. Conditions change by the hour; event organisers and local authorities publish the briefing that matters on the day.
Municipal and club pools publish lane books before open-water leaps. Red Cross / federation lessons gate beginners — a dive card is not a pool pass. Indoor 25 m is year-round; outdoor seasons follow local climate. Open-water swimming mapped for mechanisms, locale notes and limits. Rather than relying on simplified league tables or slogans, keeping the primary Open-water swimming section open beside benchmark 10 (“Olympic swimming in the sea”) gives operators and readers a verifiable decision trail.
Say Open-water swimming with 1896, “Olympic swimming in the sea,” and 10. The figure is not a booking rank. Keep Open-water swimming with “Olympic swimming in the sea” and 10 from 1896. 101896

The depth to respect is {depth}. Access score {access} does not raise it.
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.
Caribbean: 1987 (1960s)If you cannot keep {depth}, do not treat {name} as today’s session.
Atlas note 13 on Caribbean defines the operating range of 1987 when “Bonaire Marine Park” applies.

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.
