Length between perpendiculars for tonnage is ordered to be taken as follows: the fore extreme to be at the fore side of the stem, at the height of the upper deck in two-decked ships of war, frigates, single-decked vessels and merchant ships, and the middle deck of three-decked ships; and the after extreme to be at the back of the main post, at the height of the the wing transom in square-stermed ships; and in ships with elliptical sterns where the same height of the upper deck of two-deck ships, &c, or the middle deck of three-decked ships, cuts the line of the conter; these points to be squared down to the line of the lower edge of the rabbet of the keel produced, and the distance between these intersections to be the Length between perpendiculars for tonnage.
