3 Terms and Definitions

The following terms and definitions apply to this document. Note. For details on the main data units, please refer to Chapter 4. 3.1 waterline WL The line of intersection between the horizontal plane and the hull when the boat (3.15) is floating. 3.2 Maximum load waterline Reference waterline The boat (3.15) is floating at the waterline (3.1) at its maximum full load displacement (3.6). 3.3 deck sheerline The line of intersection between the deck and the hull is a normal line of intersection for the edge of a rounded deck; or, if there is no deck or the hull extends to the deck (side)... Above the wall, the upper edge of the hull is the upper edge line. Note. The upper position of the deck hull line depends on the angle between the hull/deck intersection and the actual deck. 3.4 Stern plate width transombeam BT The maximum width of the stern plate at or below the deck flank (3.3) (excluding extensions, handles and accessories). Note 1.If the splash guard is part of the bilge material or the sliding surface, it should be included when measuring the width of the stern seal. Note 2.For vessels with a rounded or pointed stern, or whose stern plating width is less than half the maximum width of the vessel (3.15), the stern plating width BT is the width along the deck flank or... The maximum width of the hull, extending one-quarter of its length forward from the stern, below the deck hull line. 3.5 Displacement The weight of the water displaced by the boat (3.15) (including all accessories). ...
