Artikel 54

The cubic capacity of a superstructure is to be determined as follows:
1. The breadths having been numbered from fore to aft, the provisions of Article 49 relating to the determination of the cubic capacity of 'tween-deck spaces shall apply for the purpose of ascertaining the cubic capacity of a superstructure. Should the length, however, have only been divided into two equal parts, the sum of the two end breadths, plus four times the middle breadth, shall be multiplied by one-third of the common interval between the breadths. The area so obtained is multiplied by the mean height and this last product gives the cubic capacity of the superstructure in cubic feet or in cubic metres.
2. In the case of the superstructures referred to in footnote 2 to paragraph 3 of Article 53 and in paragraph 4 of the said Article, the length is multiplied by the breadth, and the area thus obtained is multiplied by the mean height. This last product gives the cubic capacity of the superstructure in cubic feet or in cubic metres.
