Rule 5 — Look-out
Every vessel shall at all times maintain a proper look-out by sight AND hearing, as well as by all available means (including radar), so as to make a full appraisal of the situation and the risk of collision.
This is one of the most fundamental rules. A good look-out means using your eyes, ears, radar, AIS, and any other means. It applies in all conditions, day and night.
- Look-out by sight AND hearing at all times
- Use all available means appropriate to the circumstances; radar where fitted and operational, with AIS only as a supplement
- Applies in all weather and visibility conditions
