  "text": "Subject to the provisions of paragraph 4 below, the cubic capacity of a lifeboat for the purposes of these Rules shall be measured in cubic metres and shall be determined by Stirling's (Simpson's) Rule, which may be considered as given by the following formula:—\nCubic Capacity = L 12 (4⁢A + 2⁢B + 4⁢C) , L denotes the length of the lifeboat in metres from the inside of the shell at the top of the stem to the corresponding point at the top of the stern post; in the case of a lifeboat with a square stern the length is measured to the inside of the top of the transom; and\nA, B, C, denote respectively the areas of the cross-sections at the quarter length forward, amidships and the quarter length aft which correspond to the three points obtained by dividing L into four equal parts (the areas corresponding to the two ends of the lifeboat shall be considered negligible).\nThe areas A, B, C shall be deemed to be given in square metres by the successive application of the following formula to each of the three cross-sections:—\nArea = h 12 ⁢ (a + 4⁢b + 2⁢c + 4⁢d + e) , h denotes the depth measured in metres inside the shell from the keel to the level of the gunwale, or, in certain cases, to a lower level as determined hereafter; and a, b, c, d, e denote the horizontal breadths of the lifeboat measured in metres inside the shall at the upper and lower points of the depth and at the three points obtained by dividing h into four equal parts (a and e being the breadths at the extreme points, and c at the middle point of h).\nThe capacity of a square-sterned lifeboat shall be calculated as if the lifeboat had a pointed stern.",
