the number of persons for whom there is seating-accommodation in
the boat in question is greater than the number obtained by applying
the above divisor : Provided always that the divisor adopted in
place of 3$\frac{1}{4}$ shall never be less than 3.

(5) The number of persons obtained by the above rules shall be
reduced --

(i) If it is greater than the number of persons for which there is
proper seating-accommodation, the latter number being
determined in such a way that the persons when seated do
not interfere in any way with the use of the oars ; or

(ii) If, in the case of boats other than open boats of Class 1, the
freeboard when the boat is fully loaded is less than the
freeboard required by these rules.

(6) If a Surveyor is doubtful as to the number of persons any
boat is fit to carry he may require the boat to be tested afloat with
the intended number of persons on board.

(7) The Department may limit the number of persons to be
allowed in boats with very fine ends and in boats very full in form.

(8) Two children under the age of twelve years may be carried
in place of one adult person.

7. Cubic Capacity of Open Boats of Class 1.

(1) In the case of an open boat of Class 1 the cubic capacity shall
be determined by the following formula:

$\text{Capacity} = \frac{l}{12}\left(4A + 2B + 4C\right).$

$l$ denotes the length of the boat in feet from the inside of the
planking or plating at the stem to the corresponding point at the
stern-post ; in the case of a boat with a square stern the length is
measured to the inside of the transom.

A, 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 boat are considered negligible).

The areas A, B, C shall be deemed to be given in square feet by
the successive application of the following formula to each of the
three cross-sections :

$\text{Area} = \frac{h}{12}\left(a + 4b + 2c + 4d + e\right).$

$h$ denotes the depth measured in feet inside the planking or plating
from the keel to the level of gunwale, or, in certain cases, to a lower
level, as determined hereafter.

$a$, $b$, $c$, $d$, $e$ denote the horizontal breadths of the boat measured in
feet to the inside of the planking 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 $h$).

(2) If the sheer of the gunwale, measured at the two points
situated at a quarter of the length of the boat from the ends, exceeds
1 per cent. of the length of the boat, the depth employed in calculating
the area of the cross-sections A or C shall be deemed to be the depth
amidships plus 1 per cent. of the length of the boat.

(3) If the depth of the boat amidships exceeds 45 per cent. of the
breadth, the depth employed in calculating the area of the midship
cross-section B shall be deemed to be equal to 45 per cent. of the
breadth, and the depth employed in calculating the areas of the
quarter-length sections A and C shall be obtained by increasing this
last figure by an amount equal to 1 per cent. of the length of the
boat: Provided that in no case shall the depths employed in the
calculation exceed the actual depths at these points.

(4) If the depth of the boat is greater than 4 ft. the number of
persons given by the application of these general rules shall be reduced
in proportion to the ratio of 4 ft. to the actual depth, until the
boat has been tested afloat with that number of persons on board
all wearing life-jackets, and the test has proved satisfactory.

(5) The cubic capacity of a boat may be assumed to be the
product of the length, the breadth, and the depth multiplied by 0·6
in cases where it is clear that this formula does not give a greater
capacity than that obtained by the above method. The dimensions
shall then be measured in the following manner:
