The 9th Internarnational Hydrographic Conference, at which 37 States Members were represented, was held in the Principalty of Monaco from 18 April to 3 May 1967. The most important subject at this conference was to draft a Convention by which the International Hydrographic Bureau would be able to become a formal intergovernmental organization. The draft convention was accepted by the conference on 2 May, and representatives of 17 countries signed the convention on the following day. As for the chart, 31 items were discussed at the Chart Committee, Among them, the proposal of Japan on "Representation of the quality of the bottom on charts" was adopted, which recommends that in areas where large vessels are to lie at anchor, and where the quality of the underlayer of the bottom is known to be different from that of the surface layer, the qualities of both layers be indicated on charts. The U.S.A proposal on "Omission of detail" was also adopted, by which it is recommended that where large-scale charts exist for port areas the smaller-scale charts omit all the topographic and hydrographic details which already figure on the large-scale charts, with the exception of navigational aids and landmarks useful to coastal navigation. The proposal of France to establish a commission to study the possibility of constitution of an international set of charts was adopted, and France, Netherlands, Grest Britain, Germany, U.S.A. and Japan have been designated as the members of this commission. The Nautical Document Committee handled 19 proposals. Various views and comments were expressed and discussed as to what information is to be included in the Sailing Directions. As the result, it is recommended that Sailing Directions include all available information the objects which permit the fixing of a ship's position by means of concerningradar, and it is also resolved that the International Hydrographic Bureau shall promote the study in this connection.
