The Competition Regulations now replace the old regulations of all of our aquatic disciplines, as well as the following former rules and policies:

  • General Rules
  • By-Laws
  • Facilities Rules
  • Medical Rules
  • Swimwear and Equipment Rules
  • Advertising and Signage

World Aquatics took this step to deliver greater clarity and provide a more comprehensive rulebook across all our aquatic sports. To aid in this, the Competition Regulations text is searchable and hyperlinked throughout.
