(2) Propelling machinery space which does not extend to the ship's side and is situated below the upper deck shall be measured by ascertsiding its mean length, mean breadth and mean depth, and the product of multiplying these dimensions together shall, when divided by 100 be the tonnage of the space.
7.
The tonnage of shaft bossings and other appendages referred to in regulation 7(8) shall be ascertained by measuring the internal cubic capacity of the space as accurately as practicable and dividing the result by 100.
RULE II.
Measurement of tonnage below the upper deck where measurement in accordance with Rule 1 ly impracticable.
The length of the ship shall be measured on the upper side of the upper deck from the inside of the outer plate or plank at the stem to the aft side of the stem-post, or to the fore side of the rudder stock where no stern-post is fitted. The extreme breadth of the ship shall be measured, excluding rubbers or Benders. The girth, from the upper edge of the upper deck at side on one side of the ship to the same point A the other side, shall be measured on the outside of the ship at the greatest breadth. To half the girth thus measured there shall be added half the aforesaid breadth. The square of the sum shall be multiplied by the aforesaid length. This product multiplied by .0017 in the case of ships built of wood and by .0018 in the case of other ships shall be the tommage of the ship below the upper deck.
In any case in which the surveyor is satisfied that by reason of the size of the ship it is not reasonably practicable to measure its girth as provided in paragraph 1, such girth shall be ascertained by adding the aforesaid breadth of the ship to twice the depth of the ship from the top of the upper deck at the side of the ship to the bottom of the keel and multiplying this sum by 0.99.
SECOND SCHEDULE.
[reg. 7.]
LIMITATION OF HEIGHT OF OPEN FLOORS AND DOVOLE BOTTOMS, AND OF DEPTHS OF PRAMES AND SIDE BRACKETS, FOR PURPOSES
OF MEASUREMENT OF UNDERDECK TONNAGE
The provisions of this Schedule shall have effect for the purposes of the measurement of underdeck tonnage.
1. (1) Any part of an open floor, other than a floor in the main space for the propelling machinery of a ship, which is situated above the horizontal line hereinafter described shall be disregarded for the purposes of measurement of underdeck lonnage, which shall be measured accordingly by reference to the said line.
(2) The line above referred to shall be a line passing through a point in the middle plane of the ship at a height consisting of the maximum height of open floors applicable to a ship of the tourage length of the ship undergoing measurement, ascertained by reference to columins A and B of Table and corrected by the addition of a distance equal to the
17
rise of the moulded frame line at one quarter of the breadth of the ship between moulded frame lines at the said maximum height.
(3) The provisions of this paragraph shall also apply in the case of ships fitted with longitudinal floors and/or frames.
2. A double bottom, situated in any part of a ship other than the main space for the propelling machinery, which is of greater height than a height consisting of the maximum height of double bottom applicable to a ship of the tonnage length of the ship undergoing measurement, ascertained by reference to columns A and C of Table I and corrected by the addition of a distance equal to the rise of the moulded frame line at one quarter of the breadth of the ship between moulded frame lines at the said maximum beight, shall be treated not as a double bottom but as an open floor of such height ascertained in accordance with the provisions of paragraph 1(2) of this Schedule as would be applicable in the case of a ship of the tonnage length of the ship undergoing measurement.
3.
(1) The horizontal width of bilge brackets measured from the shell of the ship to the inboard toe of the bracket shall not-
(a) if taken at the level of the top of an open floor, chceed the maximum height of open floor applicable to the ship obtained by reference to columns A and B of Table 1;
(6) if Laken at the level of the top of a double bottom, exceed the maximum height of double bottom applicable to the ship obtained by reference to columns A and C of that Table.
(2) lo any
case in which underdeck tonnage is measured by reference to a height ascertained and applied in accordance with the provisions of paragraphs 1 and 2 of this Schedule, the lowest breadth used in the measurement of underdeck tonnage area shall to the breadth betweeD the inder sides of the shell of the ship taken at that height, less twice the maximum height of open floor applicable to the ship obtained by reference ta polumins A and B of Table I or twice the width of the bilge bracket whichever is the less.
4. The limitations imposed by the preceding three paragraphs are exclusive of an allowance for ceiling, if fitted.
5. (1) Subject to sub-paragraph (2), the extent to which the depth of transverse or longitudinal ship side framing in the case of any ship. measured from its shell, exceeds the maximum depth of frame applicable to a ship of the registered breadth of the ship undergoing measurement ascertained by reference to Table II shall be disregarded and underdeck Lounage shall be measured accordingly by reference to the maximum depth of frame so ascertained.
(2) In the case of a ship in which alternate deep and shallow frames are Aited, the depth of frame used for purposes of measurement, measured from the shell of the ship, shall not exceed whichever is the lesser of the following dimensions—
(a) twice the depth of the shallow frame, DI
(5) the maximum depth of frame applicable to the ship ascertained
as aforesaid.
(3) The limitations imposed by sub-paragraphs (1) and (2) are exclusive of an allowance for sparring fitted on the toe of the frantes,
