COLREGs Rules of the Road (ROR) — Introduction & Vessel Hierarchy | MMD Exam oral

Описание: COLREGs Rules of the Road (ROR) — Introduction & Vessel Hierarchy Explained | MMD Exam Prep
This video is an introductory session on the Rules of the Road (ROR), focusing on the COLREGs (International Regulations for Preventing Collisions at Sea), 1972 — the global standard for collision avoidance at sea.

Designed especially for Merchant Navy cadets and officers preparing for MMD written and oral examinations, this lesson builds a strong foundation by explaining how COLREGs are structured, interpreted, and applied in real navigation scenarios.

📘 What You’ll Learn in This Video

🔹 Background of COLREGs
• COLREGs 1972 as the international collision prevention convention
• Recommended reference books for exams:
– ROAR by Capt. S.K. Puri
– AROAR by Mandar
– AROAR by Capt. Yashwant Chabla
• Importance of using physical ROR cards or apps for oral exams

🔹 Structure of COLREGs
• Total 41 Rules
• Divided into Parts A to F
• Supported by 4 Annexes

🔹 Part B — Steering & Sailing Rules
• Section 1: Any condition of visibility (Rules 4–10)
• Section 2: Vessels in sight of one another (Rules 11–18)
• Section 3: Restricted visibility (Rule 19)

🔹 Rule 18 — Hierarchy of Vessels
• Understanding “hampered” vs “non-hampered” vessels
• Hampered vessels include:
– Not Under Command (NUC)
– Restricted in Ability to Manoeuvre (RAM)
– Constrained by Draft (CBD)
– Fishing vessels
– Sailing vessels
• Power Driven Vessels must keep clear of hampered vessels

🔹 Practical COLREGs Logic
• Why a fishing vessel remains hampered even with engine running
• Correct interpretation of legal words like “shall” and “may”
• Why Rule 18 priorities change in:
– Narrow channels (Rule 9)
– Traffic Separation Schemes (Rule 10)
– Overtaking situations (Rule 13)

This session sets the base for deeper understanding of collision avoidance and prepares you for advanced rules like Rules 15, 16, and 17.

Clear concepts → correct decisions → safer navigation.
