Rule XXVIII.—Side Scuttles.

Side scuttles to spaces below the freeboard deck or to spaces below the superstructure deck of superstructures closed by Class 1 or Class 2 closing appliances are to be fitted with efficient inside deadlights permanently attached in their proper positions so that they can be effectively closed and secured watertight.

Where, however, such spaces in superstructures are appropriated to passengers other than steerage passengers or to crew, the side scuttles may have portable deadlights stowed adjacent to the side scuttles, provided they are readily accessible at all times on service.

The side scuttles and deadlights are to be of substantial and approved construction.

Rule XXIX.—Guard Rails.

Efficient guard rails or bulwarks are to be fitted on all exposed portions of freeboard and superstructure decks.

Rule XXX.—Freeing Ports.

Where bulwarks on the weather portions of freeboard or superstructure decks form “wells,” ample provision is to be made for rapidly freeing the decks of water and for draining them. The minimum freeing port area on each side of the ship for each well on the freeboard deck and on the raised quarter deck is to be that given by the following scale; the minimum area for each well on any other superstructure deck is to be one-half the area given by the scale. Where the length of the well exceeds 0·7 L, the scale may be modified.

SCALE OF FREEING PORT AREA.

Length of Bulwarks in “Well” in Feet. Freeing Port Area on each Side in Square Feet.
15 8·0
20 8·5
25 9·0
30 9·5
35 10·0
40 10·5
45 11·0
50 11·5
55 12·0
60 12·5
65 13·0
Above 65 1 square foot for each additional 5 feet length of bulwark.

The lower edges of the freeing ports are to be as near the deck as practicable and preferably not higher than the upper edge of the gunwale bar. Two-thirds of the freeing port area required is to be provided in the midship half of the well. In ships with less than the standard sheer the freeing port area is to be suitably increased.

All such openings in the bulwarks are to be protected by rails or bars spaced about 9 inches apart. If shutters are fitted to freeing ports, ample clearance is to be provided to prevent jamming. Hinges are to have brass pins.

Rule XXXI.—Protection of Crew.

Gangways, lifelines, or other satisfactory means are to be provided for the protection of the crew in getting to and from their quarters. The strength of houses for the accommodation of crew on flush deck steamers is to be equivalent to that required for superstructure bulkheads.

Part III.—Load Line for Steamers.

Rule XXXII.—Length (L).

The length used with the Rules and Freeboard Table is the length in feet on the summer load water-line from the foreside of the stem to the afterside of the rudder post. Where there is no rudder post, the length is measured from the foreside of the stem to the axis of the rudder stock. For ships with cruiser sterns, the length is to be taken as 96 per cent. of the total length on the designed summer load water-line or as the length from the foreside of the stem to the axis of the rudder stock if that be the greater.
