Section 97 in The Naval Ceremonial, Conditions Of Service And Miscellaneous Regulations, 1964
97. Ceremonial for Two Ships passing between Sunrise and Sunset.
(1)When two ships pass one another, of which only one is under way-(a)if either is a ship wearing a President's flag or is a flagship or a foreign warship, the junior ships shall sound the "alert" on the bugle; the other shall immediately do likewise and after a short interval, also sound the "carry on". The junior ship shall, after a short interval, also sound the "carry on". If guards and bands are paraded, the junior ship shall give the salute applicable, as laid down in Regulations 82 to 84, the senior ship's guard receiving the salute at the "slope"; but if one of these ships is a foreign warship, a similar salute to those laid down in Regulations 82 to 84 shall be given by the junior and returned in full by the senior, the bands playing the national anthem of the foreign nation. In cases of doubt as to seniority, Indian Naval Ships shall be prepared to give the salute first at the most opportune moment, provided they are satisfied that it is likely to be returned in a similar manner;(b)if neither ship be a flagship, nor a warship of a foreign nation, the bugle shall not be used, but similar marks of respect shall be paid and returned by pipe. If guards and bands are paraded, the guards shall remain at the "slope".(2)In all cases when both ships are under way the above marks of respect shall be paid and returned by pipe only, guards if paraded, coming to the "slope". If a foreign warship under this sub-regulation should act or appear likely to act as laid down in sub-regulation (1), reciprocal action shall be taken by Indian Naval Ships passing or being passed by such warship.
