(d) 48 kilograms per running metre in the case of rigging, masts, derricks and similar high objects measured to a height of 6.1 m above the main weatherdeck.
(7) The position of the vertical centre of gravity of accumulated ice shall be calculated using the weights calculated in accordance with subsection (6) except that the following minimum values shall apply:
(7.1) [Repealed, SOR/79-903, s. 2]
(8) The following plans shall be submitted to the Board together with the stability calculations required by this section:
(a) hydrostatic curves and draught mark locations;
(b) cross curves of stability;
(c) curves of righting levers for each of the conditions specified in subsection (2);
(d) a capacity plan indicating the capacities and centres of gravity of all cargo spaces, tanks and other storage spaces; and
(e) tank sounding tables.
(9) The owners of a vessel shall provide a booklet to be placed on board the vessel for the information of the master,
(10) Subject to subsection (12), this section applies to
(11) Where an existing vessel is modified in such a manner as to affect its stability characteristics,
(a) in the case of a vessel for which the stability information required by this section is available, that stability information shall be modified and submitted to the Board for approval; and
(b) in the case of a vessel for which the stability information required by this section is not available, that stability information shall be provided to the extent considered necessary by the Board.
(12) The Board may, on application, dispense with the stability tests required by this section in respect of a vessel, if the stability data and plans required by this section have been approved for a sister vessel.

Control of Loaded Fish Nets
11 Retaining bulwarks shall be installed in, restraining tackle shall be fitted on or other suitable arrangements shall be made to every fishing vessel to ensure that loaded nets are kept fully under control and prevented from sliding to one side while they are being recovered from the water and while they are on deck.
Boilers, Steam Engines and Steam Auxiliaries
12 (1) Boilers, boiler mountings, main steam pipes, main feed pipes, evaporators, feed heaters, boiler feed systems, main shafting, main engines and oil fuel systems shall be constructed and inspected during construction as required by the Marine Machinery Regulations.
(2) Fishing vessels propelled by steam shall be provided with feed pumps and feed water system fittings as follows:
(a) not less than two entirely separate power feed pumps shall be fitted, one of which may be worked from the main engines and the other shall be an independent power pump;
(b) if a feed pump worked from the main engines is not fitted, one of the independent pumps shall be fitted with an automatic regulator for controlling its speed;
(c) each power feed pump shall be capable of performing the whole work required of feeding the boilers at full power;
(d) the independent power feed pump shall be fitted with suctions to the hotwell and the sea;
(e) the suction valves to the hotwell or feed water drain tank shall be of the non-return type; and
(f) where superheated steam is used in main or auxiliary engines of reciprocating type, filters shall be fitted to provide for the continuous filtration of the boiler feed water, and if a direct contact heater is supplied with exhaust steam from reciprocating engines, the feed water from the heater shall be led through those filters.
(3) An inspector shall satisfy himself by actual examination, and by a series of calculations when required, that
(a) the working pressure assigned to boilers, superheaters, air receivers and other pressure vessels subject to inspection can be safely carried, and is suitable for the piping and machinery;
(b) the propelling machinery is sufficient in power and capacity to enable the ship to be manoeuvred and handled at sea with a proper degree of safety, having regard to the voyages the ship is to make; and
(c) the machinery has been installed in a satisfactory manner and is sufficient and suitable for the voyages intended.
(4) Safety valves shall be set, in the presence of an inspector, to blow off at a pressure not in excess of the working pressure assigned.
(5) Where an inspector is unable to enter a boiler because the manholes are not large enough or are improperly placed, the boiler shall not be accepted until adequate means of access to the boiler is provided, except in the case of a boiler so small that entrance thereto is impossible.
(6) Boilers, boiler mountings, air receivers, main and auxiliary steam pipes over 75 mm in diameter, and other pressure vessels that are subject to inspection and are being inspected for the first time shall be tested by hydraulic pressure as specified in Schedule III after the working pressures have been ascertained in accordance with the Marine Machinery Regulations.
(7) Safety valves on cylindrical boilers being inspected for the first time, or new safety valves fitted to cylindrical boilers, shall be subjected to the following accumulation test after the safety valves have been set to the assigned pressure:
(a) during a test of 15 minutes with the stop valves closed and under full firing conditions, the accumulation of pressure shall not exceed 10 per cent of the rated pressure;
(b) during the test referred to in paragraph (a), no more feed water shall be supplied than is necessary to maintain a safe working water level.
(8) Subject to subsection (9), safety valves on water tube boilers being inspected for the first time, or new safety valves fitted to water tube boilers, shall be subjected to the following accumulation test, after the safety valves have been set to the assigned pressure:
(a) during a test with the stop valve closed and under full firing conditions, for as long a time as the water supply in the boiler permits, the accumulation of pressure shall not exceed 10 per cent of the working pressure; and
(b) in no case need the test referred to in paragraph (a) exceed seven minutes.
(9) Where accumulation tests may endanger the superheater, oilfired boilers may be exempted therefrom if application for exemption is made when the boiler plans and sizes of safety valves are submitted for approval, and the safety valves are of an approved type
(10) Where exemption is granted pursuant to subsection (9),
