Artikel 82

When the propelling-machinery spaces have been measured as indicated in Article 80 and the restrictions referred to in Article 81 have, if necessary, been applied, the cubic capacity of the propellingmachinery spaces is ascertained as follows:
The cubic capacity of each space (or each part of a space, as the case may be) is calculated separately by first multiplying its length by its breadth. The area thus obtained is then multiplied by the depth (height) and this last product constitutes the cubic capacity of the space (or of the part of the space, as the case may be) in cubic feet or in cubic metres.
If more than one breadth has been measured, the arithmetic mean of the breadths shall be used in the calculation; the same provision shall apply with regard to the depths (heights).
