A draught survey is a method of cargo weight determination by ship’s displacement calculations, empty and loaded (or loaded and empty), taking into account any change in weight of the liquids on board.
The accuracy of the draught survey will be dependent upon the experience and the care taken by the surveyor concerned, on the documentation of the vessel, on the spirit of co-operation of the vessel crews and of the shore terminal personnel and, last but not least, on the instruments used by the draught surveyor and the weather and sea conditions in the harbour.
The tendency of a floating vessel to return to its original upright position of equilibrium after being tipped by the forces of wind and sea.
Is defined as the difference between the draft forward and the draft aft. Draft is the depth of the hull below the water.
