Artikel 67

Subject to the provisions of Article 79 relating to the treatment of donkey-boiler spaces which may be regarded as part of the propelling-machinery space, the space actually occupied by donkeyboilers, if connected with the main pumps of the ship, shall be deducted, even if the donkey-boilers may be used at the same time for working the cargo winches or for similar purposes.
If the donkey-boilers are not connected with the main pumps, but serve exclusively for the working of the capstan, anchor-gear, steeringgear or similar appliances for navigation purposes, the space occupied may be regarded as navigation space, and therefore shall be deducted as such.
Spaces occupied by and necessary for the working of bilge pumps and for exclusive access to same shall be deducted. The same provision shall apply to pumps for water ballast, if available for pumping out the ship.
If a donkey-boiler, a bilge pump or a water-ballast pump, fulfilling the above conditions, is situated within the boundaries of the propelling-machinery space and is not to be regarded as part of the propelling machinery, only the spaces strictly occupied by the said appliances shall be deducted and stated on the formulas of measurement under Spaces for Navigation and Working of the Ship.
