Read first Water sports carry drowning, pressure and medical risks. Use certified instruction, check conditions, and never treat depth or time tables as personal clearance.
How to use this guide Match skill to site Start in controlled water, then add current, depth and night only with training.Verify agency path PADI, SSI, CMAS and national programs differ on medical and depth rules.Expert voices Conditions beat gear: abort early when visibility, current or buddy signals change. Dive instructor — Site briefings Quick answers Do I need a medical form? Most agencies require a questionnaire or physician clearance before confined or open-water training.
How do seasons affect sites? Visibility, current, temperature and wildlife access change by month — check local charts and operators.
Key data Band Teaching use Depth band Agency training limits — not a personal clearance. Visibility Site and season dependent; abort when buddy contact is lost.

Can I copy a site’s depth for my plan? Treat listed depths as teaching envelopes. Real plans need charts, guides and conditions that day.
Buddy requirement? Recreational systems usually train with a buddy. Solo requires extra training and local permission.

Competitive swimming is the measured, judged version of pool swimming: four strokes, relays, and a clock that records to hundredths. World Aquatics (FINA until 2022) writes the rulebook that clubs, schools and the Olympics share.
Most of the world’s racing happens in short-course 25-metre halls, not in Olympic finals. The skill ceiling in this atlas is high because technique, training load and race craft stack for a decade. Risk stays low relative to wreck or night diving: the hazards are overuse and the rare shallow-water dive, not current.
This chapter is a club-sport map, not a governing-body medical screen and not a live meet brief. Memberships and qualifying times belong to national federations.
Educational atlas, not a certifying agency and not medical or rescue advice. Local parks, skippers and instructors have the last word on conditions.

Frequently asked questions Which local rescue or training agency should I check first? Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
Why do 25 m and 50 m records differ? More walls in a 25 m pool mean more push-offs. World Aquatics keeps separate short-course and long-course lists.
When did FINA become World Aquatics? The federation rebranded in 2022. The 1908 founding date did not change.
Are tech suits allowed? Textile suits with coverage rules replaced the 2008–2009 polyurethane spike. National bodies publish the current approved list.
Is this the same as triathlon swimming? No. Triathlon swimming is open-water, usually wetsuit-banded, and ends in a transition. Pool racing is stroke-legal and wall-based.
How do people join? A club, a time trial, and a meet entry. There is no PADI-style card; there are memberships and qualifying times.
What is a DQ? A disqualification for a stroke or turn infraction — a legal, not a moral, event.
Does racing need medical clearance? Some federations ask for a form. This atlas is not medical advice and not a governing-body medical screen.
