Where the required stern height is obtained by sheer or superstructure, the extension shall not be less than 0.05L; (e) Ships operating in restricted area III and operating solely on harbour and roadstead service may reduce the bow height to not less than 0.5m and the stern shall not be less than minimum midship height; (f) The deck line is a horizontal line 200mm in length and 20mm in breadth. It shall be permanently marked amidships on each side of the ship to the satisfaction of the Administration, and its upper edge shall normally pass through the point where the continuation outwards of the upper surface of the freeboard deck intersects the outer surface of the shell; (g) The freeboard mark shall consist of a ring 200mm in outside diameter and 20mm wide which is intersected by a horizontal line 300mm in length and 20mm in breadth, the upper edge of which passes through the centre of the ring. The centre of the ring shall be placed amidships and at a distance equal to the assigned freeboard measured vertically below Merchant Ships (Registration) 142 the upper edge of the deck line. The mark shall be permanently marked on the sides of the ship to the satisfaction of the Administration; (h) The mark of the authority by whom the load lines are assigned may be indicated alongside the load line ring above the horizontal line which passes through the center of the ring, or above or below it. This mark shall consist of not more than four initials to identify the authority’s name, each measuring approximately 115mm in height and 75mm in width.
