️ COLREG Rule 19: Conduct of Vessels in Restricted Visibility

Restricted visibility—such as fog, mist, heavy rain or snow—requires extra caution because the risk of collision increases significantly.

Proceed at a safe speed suited to the prevailing conditions
Maintain a proper lookout by sight, hearing and all available means
Listen carefully for fog signals and other warning signals
Use radar and other navigation aids effectively to assess traffic and collision risk
If in doubt about collision risk: take appropriate action immediately
Sound the prescribed fog signal when required

Fog Signal: A power-driven vessel making way through the water sounds one prolonged blast at intervals of not more than 2 minutes.

KEY TAKEAWAY:
Restricted visibility demands safe speed, vigilant lookout, effective use of radar and early action.

SAFETY FIRST • GOOD JUDGEMENT • AVOID COLLISIONS
