ABSTRACT
Russian commentaries to COLREG-72 don’t at all consider the problem of quantitative criteria as applied to Rule 14, i.e. of minimum permissible aspect of oncoming vessel when it is to be considered as the vessel proceeding on reciprocal course head-on. In Russian commentaries to COLREG-72, complying with Rule 14, it is recommended in any doubt to use
Rule 14 for altering the course “ahead of time and positively” to starboard.
