Artikel 37

The upper breadth, situated at the level of the upper extreme point of the tonnage depth, must be measured immediately below the tonnage deck. Should it not be practicable to measure the breadth below the deck, the measurement may also be taken on top of the deck; but in this case it should be ascertained whether the depth of frames below and above the deck is the same and whether the sides of the ship at the level of the deck are vertical. Should the depth of frames above the deck be different from that below the deck, the measured breadth shall be corrected as indicated in Figure 43. Should there be either tumble-home or flaring sides, the measured breadth shall be corrected as indicated in Figure 44.
