COLREGs

• Run a command-level collision-avoidance sequence: establish context, build and share the traffic picture, determine risk, apply every relevant rule, then verify the outcome.
• Use Rule 2 to preserve ordinary seamanship and respond to special circumstances without treating it as permission to improvise away from the Rules.
• Organise and hand over a continuous lookout that combines people, sight, hearing, radar and other appropriate means into one shared traffic picture.

A self-guided revision companion that explains essential concepts, then helps you practise and test them. It supports—but does not replace—recognised instruction, practical training, assessment or certification. Access is a one-time payment, not a subscription.
