(d) the German Government is in favour of the issue of the limitation of naval armament of the system which divides naval ships into categories, fixes the maximum mass and/or armament for ships of each category and allocates the tonnage authorized to each power by category of ships. Consequently, the German Government is prepared, in principle and subject to point (f), to apply the 35%. to make the ratio to the tonnage of each category receivable subject in one or more specific categories to the rules that may be adopted in a future general contract for the limitation of the navy, on the basis of the principle that any increase in one category would be offset by a corresponding reduction in other categories. If one does not want to enter into a general contract of limitation of the navy or if the future general contract does not contain a provision that creates a limitation by category, the way in which the federal government has the right to vary the 35 per cent. Relations in one or more categories will be a matter of consensus between the German Government and Her Majesty`s Government in the United Kingdom, in the light of the naval situation that existed at the time. All seagoing vessels with a length of 24 m or more require an International Tonnage Certificate 1969 (ITC 69) and a Tonnage Certificate (National) with a length of less than 24 metres. The length shall be measured in accordance with Article 2(8) of the International Convention on the Survey of Ships, 1969 (ITC). Please read our additional information on this international measurement method. Given the great diversity of the size of the two navies, this threat could only be eliminated if the British construction remained stationary for a considerable period of years, while the German tonnage was built on this basis. .
