If you notice Ankur, overtaking situation in Rule 19 is somewhat like rule 13. It asks the vessel being overtaken to avoid alteration toward the other vessel. It does not tell us to take any action in particular. In the situation you mention, Unless we have communicated with other vessel, we need to keep our course and speed. Once the other vessel has altered her course to port or starboard we can alter our course in the opposite direction in opposite direction to increase the CPA if required.

If there is restricted visibility, overtaking situation do not apply as rule 13 applies in sight of one another. So in this case we need to follow TSS as well as rule 19. As per rule 19 D (i) we can alter any side (port or starboard) to overtake.

Follow rule 19D (i) and overtake from either side. Rule number 13 would not apply.

Rule 18 (which include NUC) applies in sight of one another. So NUC does not apply in restricted visibility. As per rule 19, there is no NUC vessel so we do not need to know if an vessel is NUC or not.

Sir kindly explain with reference to the photo which says action as per a1 .As you have a target on starboard quarter,nearly dead stern.why will you consider an optio to alter course to starboard as the rule says avoid altering towards a vessel abeam or forward of the beam.

if you check again, you will realise that the vessel you are talking about is our own vessel...so we are overtaking the other vessel..
