Скачать или смотреть Rule 19 – Conduct of Vessels in Restricted Visibility

Got it 👍 — let’s go through Rule 19 of COLREGs (International Regulations for Preventing Collisions at Sea, 1972) step by step.

🔹 Rule 19 – Conduct of Vessels in Restricted Visibility

This rule applies when vessels are not in sight of one another (for example, in fog, heavy rain, or snow).


---

📌 Key Points of Rule 19

1. Safe Speed & Engines Ready

Every vessel must proceed at a safe speed.

Engines must be ready for immediate maneuvering.

Reason: In fog, visibility is reduced — collisions can happen suddenly.



---

2. Use of Radar (if fitted)

If the vessel has radar, it must be used properly.

Radar plotting or equivalent means must be used to detect and avoid collision risk.



---

3. Lookout by Sight and Hearing

A proper lookout must be maintained, paying special attention to sound signals and radar information.



---

4. Avoiding Collision (Radar Observations)

If you detect another vessel by radar alone:

Avoid altering course to port for a vessel forward of the beam (unless overtaking).

Avoid altering course towards a vessel abeam or abaft the beam.




---

5. When Risk of Collision Exists

If you hear a vessel’s fog signal forward of your beam OR

If radar shows a vessel close by ahead,
👉 Take action to reduce speed to the minimum needed to stay on course.
👉 Sometimes, a vessel may need to stop completely and proceed only when it is safe.

🔹 Simplified Summary

In restricted visibility:

1. Go slow and keep engines ready.


2. Use radar & sound signals effectively.


3. Don’t make dangerous course alterations (like turning to port blindly).


4. If another vessel is close by, slow down or stop until safe.

✅ In short: Rule 19 is about extra caution in fog or poor visibility: safe speed, engines ready, proper lookout, careful radar use, and safe collision-avoidance actions.
