Collision Regulations
RIEAM / COLREGs: find definitions, rules and official sources with their context visible.
Start learningNavigation rules deserve more than slogans. This manual starts with a map of the regulations: where definitions appear, which parts cover lights and signals and how to read a rule or annex reference. Portuguese uses RIEAM; English uses COLREGs. Sources retain their edition, authority and consultation date. Application and procedure chapters advance through documented qualified review. Learn to locate a subject from the outset while distinguishing an educational summary from regulation text or a decision in a real encounter.
A map of the document for learning rules without reducing them to isolated phrases.
Small letters and numbers help locate the text and distinguish a rule from commentary.
