Definition And Regulation

freeboard to provide a reserve of buoyancy when a ship moves through waves, to ensure an adequate range of stability and enough bouyancy following damage to keep the ship afloat long enough for people to get off.

Freeboard is measured downwards from the freeboard deck which is the uppermost complete deck exposed to the weather and sea, the deck and the hull below it having permanent means of watertight closure. A lower deck than this can be used as the freeboard deck provided it is permanent and continuous fore and aft and athwartships. A basic freeboard is given in the Load Line Regulations, the value depending upon ship length and whether it carries liquid cargoes only in bulk. This basic freeboard has to be modified for the block coefficient, length to depth ratio, the sheer of the freeboard deck and the extent of superstructure. The reader should consult the latest regulations for the details for allocating freeboard. They are to be found in the Merchant Shipping (Load Line) Rules.

When all corrections have been made to the basic freeboard the figure arrived at is termed the Summer freeboard. This distance is measured down from a line denoting the top of the freeboard deck at side and a second line is painted on the side with its top edge passing through the centre of a circle, Figure 3.5.
