Regulation 20 - Requirements for shipborne navigational systems and equipment and performance standards
5.5 The Sub-Committee noted that, at its forty-fourth session, having considered proposals by Germany and the Netherlands (NAV 43/5), Japan (NAV 44/5/14 and NAV 44/5/16), the Russian Federation (NAV 44/5/11), the United Kingdom (NAV 44/5/12), CIRM (NAV 44/1/7) and FOEI (NAV 44/5/5) on paragraphs 1.1 to 1.9, it had agreed in principle on the requirements contained therein, as amended.

.1 the safety of navigation could be improved by the introduction of more advanced technology; however, the expansion of carriage requirements and provision of new equipment and systems should be carefully considered from a cost-effective viewpoint;
.2 the additional equipment proposed would cost domestic Japanese ships between 150 and 300 gross tonnage about US$12,000; ships between 300 and 500 gross tonnage about US$50,000; and ships of 50,000 gross tonnage and upwards about US$150,000 (the installation cost for each equipment not included in these figures); and
