Ship Nomenclature

Load Line Length(m)- taken as 96 per cent of the total length on a waterline at 85 per cent of the least moulded depth measured from the top of the keel, or as the length from the fore side of the stern to the axis of the rudder stock on that waterline, if that is greater. In ships designed with a rake of keel, the waterline on which this length is measured is to be parallel to the designed waterline. The length is to be measured in metres.
LR Scantling Length-Rule length, is the distance, in metres, on the summer load waterline from the forward side of the stern to the after side of the rudder post or the centre of the rudder stock if there is no rudder post. L is to be not less than 96 per cent, and need not be greater than 97 per cent, of the extreme length on the summer load waterline.
The ship�s Draught D is the vertical distance from the waterline to that point of the hull which is deepest in the water The foremost draught D_F and aft most draught D_A are normally the same when the ship is in the loaded condition.

The Scantling Draught is the ships design draught and is equal to the Summer Load Line draught.
Breadth on waterline BWL-the largest breadth on the waterline B_WL
