(a) The trackways of the skids shall be constructed of 6 x 3\1/2\ x \1/2\ structural angles, or of material of approved shape and equivalent strength, inclined approximately 60 degrees from the horizontal. The trackways shall be spaced 8[foot]-4 from the inside of the 3\1/2\ vertical leg of one trackway angle to the inside of the 3\1/2\ vertical leg of the other trackway angle. The inside of the 6 leg of the trackway angles shall form the skid surface for the life raft. The trackways shall be supported by a substantial structure suitable for stowing a Type A life raft at a 60-degree angle without having the raft project over the side of the vessel.
(b) The lower end of the life raft shall be supported by a base plate so arranged as to permit launching of the raft by a quick release assembly.
(c) All bearing surfaces of the quick release mechanism shall be constructed of non-corrosive metal. Alemite fittings shall be provided to insure positive lubrication of all bearing surfaces.
