Section 329(3) in The Naval Ceremonial, Conditions Of Service And Miscellaneous Regulations, 1964
(3)In addition, a break in "Very Good" conduct may be imposed as a separate naval penalty. Further, it is within the discretion of the Commanding Officer to regard any reprehensible act, for example a repeated contraction of venereal disease, any particular naval offence or a series of minor offences as breaking the continuity of "Very Good" conduct, even though a character assessment below "V.G." is not involved. A break shall not be awarded as a punishment or as a substitute, but it may accompany any punishment if the Commanding Officer considers that the circumstances justify such a course.
