Pool swimming in 1800: Baths before sport — Section 1173: Baths before sport
Atlas note 1173 on Pool swimming defines the operating range of 25 when “Baths before sport” applies. Walls, lines and a known depth remove current, swell and sighting. Open-water chapters cover the skills the pool cannot teach. Keep Pool swimming with “Baths before sport” and 25 from 1800. Artificial basins are older than sport swimming. Roman thermae and later Ottoman hammams were social and hygienic spaces. Compet
Lane discipline, stroke mechanics and public-bath access — the lowest-friction way most people first meet structured water time. Pool swimming is the controlled version of a human skill that used to be learned in rivers and harbours. Chlorination, lane ropes and depth markings turned a public-health project of the late nineteenth century into the default first water classroom.
World Aquatics (formerly FINA, founded 1908) still writes the competition rulebook, but most pool hours are not racing: fitness laps, school lessons and municipal recreation. The same 25-metre basin can hold a masters set at 06:00 and a learn-to-swim class at 16:00. This atlas treats the pool as infrastructure — access, etiquette, coaching lineages and the gap between a public bath and a FINA-standard 50-metre hall — not as a race preview. Open-water and competitive chapters sit beside it.
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. Pool swimming mapped for mechanisms, locale notes and limits. Pool swimming sits in the swim atlas — mechanisms, locale notes and limits, not slogans.
Say Pool swimming with 1800, “Baths before sport,” and 25. The figure is not a booking rank. Keep Pool swimming with “Baths before sport” and 25 from 1800. 251800

Interactive Scenario & Decision Matrix
Select your current objective to inspect the recommended benchmark, threshold, and verification path.
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.
Caribbean: 1987 (1979)Reading 4 of Caribbean uses “Hol Chan” and figure 1979 as a checkable baseline.
Dossier 14 for Caribbean links case “Hol Chan” directly to metric 1979 (1987).

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.
