Artikel 33

When the tonnage depth has been ascertained, the common interval between the breadths is determined by dividing the depth by the divisor indicated in Article 32. The points of division are now set off on one of the measuring rods, starting with the lowest point of division and setting off the common intervals from this point. When marking off the lowest point of division, care must be taken that this point is situated at the correct level above the actual lowest point of the tonnage depth.1) In the case of a ship with a horizontal tank-top athwartships and a ceiling fitted on grounds, the measuring rod should be placed on top of the ceiling. The lowest point of division is now ascertained by setting off the common interval minus the height of grounds.
