COLREGS Rule 2: Here is the Simple Explanation to the Most Confusing Rule

44
Rule-2-of-the-COLREGS-2 Collision regulations are the bible for the navigators. This is the area onboard that do not distinguish between a fresh third mate and an experienced captain. Everyone who is supposed to keep an independent navigational watch on wheelhouse is supposed to have the same level of understanding of each rule of the road. The problem is that the rules of the road though carefully drafted; have not been written in an easy language that everyone can understand. There is a lot of scope to read between the lines. For example, While there is a rule on the narrow channel the definition of narrow channel is left to the interpretation of the seafarers. Rule 2 of the COLREGS (Responsibility) is one such rule. In this post, we will discuss the rule 2 of the COLREGS. Why Rule 2 was required? Some cooks do not like to be told how to cook food on ships. Once upon a time, someone on a ship told the chief cook that his food, though very good always have a little bit of extra salt. Next day onwards he found the food with absolutely no salt in it. Rule 2 of the COLREGS aims to avoid a similar situation with the collision regulations. Each rule of the COLREGS has specified the exact actions that need to be taken by each vessel on a collision course. But what if some seafarers followed th...

    Thanks for explaining in simple language Sir. Can you pls explain what would be the ideal action in 2nd scenario where we have one head on vsl at 6NM and Shallow patch on stbd side. As stbd alteration is not possible and reducing speed will take longer time to be apparent to the other vsl and say we reduced our speed but target vsl is still not taking any action?

    Not ending up in situations like this is exactly what "ordinary practice of seaman" means. But if we have managed to land ourselves in this situation, ideally we need to get in touch with the other vessel well in time. If that was not possible we need to assess if we can alter a bit to starboard and pass the other vessel with little lesser than usual CPA. If you are already on the edge and there is absolutely no room on starboard side and the only possible way is to alter to port we must do that by altering 90 degrees or so. And more importantly do that when the other vessel is still more than 5 miles. We must not think of altering to port when the other vessel is in close range as if the other vessel realise her duty at the wrong time and alter her course to starboard that would be chaos.

  • john August 15, 2018
    Good Day Sir , Pls clarify my doubt .when vessel heading North & sees a north cardinal mark, we are running into danger,so what are the heading we can call we ruining into danger when a north Cardinal is right a head ......example if i see a north cardinal on my right head & heading between 315 to 045 ????

    Rajeev Jassal October 14, 2018
    It is not related to the our ship's heading. The danger is north of the cardinal mark.
    Achin Hatkar November 6, 2018
    If we are seeing north cardinal mark on our right ahead it means we are already running into danger....The safe water lies north side of north cardinal mark.. Please correct if i am wrong..
  • Jithesh Unnikrishnan August 26, 2018
    We have neither violated rule 13 (overtaking) nor rule 9 (traffic separation schemes). Sir there is a mistake here in this line . Please correct it as rule 10 instead of 9

    A cardinal mark is a sea mark (a buoy or other floating or fixed structure) used in maritime pilotage to indicate the position of a hazard and the direction of safe water. Cardinal marks indicate the direction of safety as a cardinal (compass) direction (north, east, south or west) relative to the mark.

    Very well explained Sir, I agree with you that Rule No. 2 has been the most confusing Rule of ROR mainly due to it's different interpretations by navigators. With regards, Capt. Anand
