“ Spaces under decks or coverings having no other connection with the body of the ship than the stanchions necessary for their support are not spaces separated off, but are spaces permanently exposed to the weather and the sea and are not to be included in the gross tonnage. ”

“ Should the open space within a poop, forecastle, bridge house, superstructure, or erection between the end opening and a parallel line distant from the opening by half the breadth of the deck become, because of any arrangement, of less width than half the breadth of the deck, then only the space between the line of the end opening and a parallel line drawn through the point where the athwartship width of the open space within the poop, forecastle, bridge house, superstructure, or erection becomes equal to, or less than, half the breadth of the deck shall be exempted from measurement. ”

“ When the shafts of screw propellers pass through open spaces not inclosed within tunnels, the spaces allowed in lieu of tunnels must be of reasonable dimensions suitable for the vessel in question. When a portion of the space within the boundary of the engine or boiler rooms is occupied by a tank or tanks for fuel oil or fresh water, the space considered to be within the engine room shall be reduced by the space taken up by the tank or tanks for fuel oil or fresh water. ”

“ Art. XXIII. The actual displacement of warships shall be determined from their official displacement scale and curves, and shall be expressed in tons of 2,240 pounds. Should the displacement scale and curves of a warship show or state the vessel's displacement tonnage in metric tons of 2,204.62 pounds, the tonnage so expressed shall be multiplied by 0.9842 for the purpose of converting the tonnage into tons of 2,240 pounds. ”

“ On colliers, coal, coaling gear, and fuel oil not for the use of the colliers. On supply ships, stores, supplies of all kinds, distilling machinery and distilled water (other than feed water stored in double-bottom compartments) , machines, tools and material for repair work, mines and mining material, torpedoes, arms, and ammunition. On hospital ships, food stores for passengers, medical stores, and hospital equipment. Guns mounted on transports and supply ships, for defense of the ships, and ammunition required for use in such guns shall not be classed as cargo. ”

“ Propelling power deduction for vessels with bunkers having movable partitions, or having fuel-oil compartments that may be used to stow cargo or stores.
Art. XIII. In ships that do not have fixed bunkers, but transverse bunkers with movable partitions, with or without lateral bunkers, and in ships with fuel tanks or double-bottom fuel compartments which may be used to stow cargo or stores, measure the space occupied by the engine rooms, and add to it for vessels with screw propellers 75 per cent and for vessels with paddle wheels 50 per cent of such space. ”

“ Multiply the quantity thus obtained by one-third of the common interval between the breadths, and the products shall be deemed the transverse area of the upper part of the section; then find the lower part of the area as before directed, and add the two parts together, and the sum shall be deemed to be the transverse area. ”

“ Art. XVIII. The Panama Canal tonnage certificates issued by the measurement authorities of the United States and the several foreign countries shall correspond in substance and form to the sample certificate appended to these rules. Blank certificates in English will be furnished by the Secretary of War or the Governor of the Panama Canal upon request of the measurement authorities of foreign countries. ”
