9. (1) On completion or near completion of a vessel, an inclining experiment shall be conducted in the presence of and to the satisfaction of a steamship inspector.
(2) The results obtained from an inclining experiment shall be developed to indicate the stability of the vessel in the following conditions:
(b) port departure;
(c) arrival at fishing grounds;
(d) half load;
(e) full load;
(f) worst operating condition affecting stability;
(g) worst operating with accumulated ice on topsides and rigging; and
(h) port after discharge of cargo with 10 per cent of fuel, fresh water and stores remaining and accumulated ice on topsides and rigging.
(3) The results obtained from an inclining experiment shall be further developed to indicate the stability of the vessel when loaded with fish of species having different stowage characteristics in conditions described in paragraphs (2)(d), (e), (f) and (g).
(4) Notwithstanding subsection (2), the results obtained from an inclining experiment are not required to be developed to indicate the stability of a vessel in conditions described in paragraphs (2)(g) and (h) unless the vessel is to be operated in or transferred to the northern or eastern waters of Canada.
(5) Where appropriate to the trade of a vessel, in the development of the results obtained from an inclining experiment, an allowance shall be made for the stowage of fish on the deck of the vessel.
(6) In developing the results of an inclining experiment to indicate the stability of a vessel in conditions described in paragraphs 2(g) and (h), accumulated ice shall be deemed to weigh
(a) 54 kg/m2 of total deck area, including the superstructure and deckhouse tops that are exposed to the weather;
(b) 37 kg/m2 of area exposed to the weather in the case of the superstructure and deckhouse fronts, and the deckhouse sides and bulwarks including the area of the deckhouse sides and bulwarks on both sides of the vessel except that only the inboard surfaces shall be included in computing the bulwark areas;
(c) 78 kg/m2 of area, taking into consideration overall block dimensions, in the case of the guardrails and stanchions, hatch coamings, companionways and ship fittings exposed to the weather; and
(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:
(a) in the case of side trawlers, the minimum height of the vertical centre of gravity shall be 2.44 m above the main weatherdeck; and
(b) in the case of stern trawlers, the minimum height of the vertical centre of gravity shall be 1.22 m above the main weatherdeck.
(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,
(a) indicating the stability characteristics of the vessel;
(b) containing appropriate information relative to loading in the various conditions specified in this section; and
(c) generally set up in a form similar to the specimen page in Schedule VIII.
(10) Subject to subsection (12), this section applies to
(a) every vessel the keel of which is laid on or after March 2, 1967;
(b) every vessel built outside of Canada for which application for registry in Canada is approved; and
(c) to the extent considered necessary by the Board, to every existing vessel.
(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.
