(2) In the case of an existing unmarked lifeboat, or other equipment that has been accepted by the Board as a lifeboat, the inspector concerned shall, if satisfied that all conditions stipulated by the Board have been met, mark such lifeboat or equipment in accordance with paragraphs (1)(a), (b) and (d).
[...]
10 Lifeboats built outside Canada may be accepted as equipment complying with these Regulations if they are

12 The cubic capacity of a lifeboat shall be measured in cubic metres and, subject to section 15, may be determined by Stirling’s (Simpson’s) Rule, where
[...]
where h denotes the depth measured in metres inside the planking or plating, from the keel to the level of the gunwale or a greater depth, as determined in sections 13 and 14, and a, b, c, d and e denote the horizontal breadths of the lifeboat measured in metres inside the planking or plating at the upper and lower points of the depth and at the 3 points obtained by dividing h into 4 equal parts (a and e being the breadths at the extreme points, and c at the middle point of h), the capacity of a square sterned lifeboat being calculated as if the lifeboat had a pointed stern.
[...]
22 The prototype of a lifeboat, other than a glass reinforced plastic lifeboat, shall be subjected to the following tests:
-
(a) it shall be suspended by the lifting hooks or releasing gear, the length, breadth and depth measured, and evenly distributed weights shall then be placed in the boat equal to the weight of
[...]
and after the weights are removed there shall be no appreciable permanent set as a result of this test; and
[...]
24 The buoyancy appliances of a Class 1 wooden lifeboat shall be
-
(a) so placed in the lifeboat as to secure stability when the lifeboat is fully laden under adverse weather conditions; and
-
(b) equal in volume to at least 10 per cent of the cubic capacity of the lifeboat, but in a lifeboat approved for 100 or more persons the volume shall be increased as the Board may prescribe.
[...]
29 Buoyancy appliances other than metal air cases shall be

-
33 (1) Stems and sternposts shall be rabbeted so as to receive the butt edges of the planks and to permit caulking but the length of the rabbet shall not exceed the thickness of the plank.
-
(2) Stems and sternposts shall not project above the gunwale more than is necessary for the securing of the upper breast hook and shall be so shaped so as to minimize risk of fouling by rope or wreckage.
[...]
47 Thwarts shall be fitted as low in the lifeboat as practicable and not less than the following distance below the gunwale:
[...]
50 Side benches shall be continuous, permanent and fitted in as long lengths as possible.
51 Gangboards shall be of the same dimensions and materials as the thwarts.
[...]
54 A plughole, so placed as to drain the lifeboat, shall be provided.

-
(2) Rivets and rolled or extruded shapes such as the keel, stem, sternpost and gunwale shall be made by the open-hearth or electric furnace process in accordance with A.S.T.M. Standard Specification A7 but consideration will be given to the use of other steel having equivalent strength where longitudinal cold forming is necessary.

[...]
-
(3) Limber holes shall be cut in floors and shall be so located as to provide efficient drainage.
-
(4) Limber holes shall be so arranged that the load on the floors is taken by the keel as well as by the shell plating.
[...]
69 Thwarts, side benches, cleading, lower cross or side seats, stretchers, stanchions, bottom boards and rudder shall normally be of wood as specified for wooden lifeboats.

-
[...]
-
(6) Woven glass fibre reinforcements if used shall be in the desized state and finished so as to provide good resin to glass adhesion and laminated wet strength retention.

-
(2) A sample laminate shall be flat, 300 mm square and made with 610 g/m2 (or equivalent) chopped strand mats and the chopped strand mats, the resin mix, the resin to glass ratio, gel coat and the curing conditions for the sample laminate shall be as proposed for the lifeboat.

81 (1) Where half shell mouldings are used for a lifeboat, or internal glass reinforced plastic structures such as buoyancy units, bulkheads, floors, seats and thwarts are not laid-up integral with the shell, full details of the proposed methods for fixing and joining these items shall be submitted to the Board.
-
(2) The following means of connection are acceptable for use in G.R.P. work:

-
85 (1) A prototype G.R.P. lifeboat shall be tested as prescribed in section 21 and paragraph 22(b) of this Schedule, and shall be subjected to the additional tests prescribed in subsections (2) to (6).
-
(2) A 100 per cent overload test shall be made with the lifeboat suspended freely by the lifting hooks or releasing gear and evenly distributed weights shall be loaded incrementally and measurements at full load, 25 per cent, 50 per cent, 75 per cent and 100 per cent overloads shall be recorded as follows:

-
(4) The lifeboat shall be loaded as for the test prescribed in subsection (3) and then suspended freely by the lifting hooks or releasing gear with the falls 6.1 m in length and arranged so that the gunwale on one side of the boat is about 50 mm from a stationary wall or other structure of similar rigidity and the lifeboat shall then be moved outboard a distance of 2.44 m horizontal from its original position and shall be allowed to swing freely and strike the wall along one side.
