LIFE-SAVING APPLIANCES, &c.

REGULATION XXIV.

Standard Types of Boats.

The standard types of boats are classified as follows:—

Class I.—Open boats with rigid sides having either (a) internal buoyancy only, or (b) internal and external buoyancy.

Class II.—(a) Open boats with internal and external buoyancy—upper parts of sides collapsible, and (b) decked boats with either fixed or collapsible watertight bulwarks.

No boat may be approved the buoyancy of which depends upon the previous adjustment of one of the principal parts of the hull, or which has not a cubic capacity of at least 3·5 cubic metres (equivalent to 125 cubic feet).

No boat may be approved the weight of which when fully laden with persons and equipment exceeds 20,300 kilogrammes (equivalent to 20 tons).

REGULATION XXV.

Lifeboats of Class I.

Lifeboats of Class I must have a mean sheer at least equal to four per cent. of their length.

The air cases of lifeboats of Class I shall be so placed as to secure stability when fully laden under adverse weather conditions.

In boats certified to carry 100 or more persons the volume of the buoyancy shall be increased to the satisfaction of the Administration.

Lifeboats of Class I must also satisfy the following conditions:—

(a) Lifeboats with Internal Buoyancy only.

The buoyancy of a wooden boat of this type shall be provided by watertight air-cases, the total volume of which shall be at least equal to one-tenth of the cubic capacity of the boat.

The buoyancy of a metal boat of this type shall not be less than that required above for a wooden boat of the same cubic capacity, the volume of watertight air-cases being increased accordingly.

(b) Lifeboats with Internal and External Buoyancy.

The internal buoyancy of a wooden boat of this type shall be provided by watertight air-cases, the total volume of which is at least equal to seven and a half per cent. of the cubic capacity of the boat.

The external buoyancy may be of cork or of any other equally efficient material, but such buoyancy shall not be obtained by the use of rushes, cork shavings, loose granulated cork or any other loose granulated substance, or by any means dependent upon inflation by air.

If the buoyancy is of cork, its volume, for a wooden boat, shall not be less than thirty-three thousands of the cubic capacity of the boat; if of any material other than cork, its volume and distribution shall be such that the buoyancy and stability of the boat are not less than that of a similar boat provided with buoyancy of cork.

The buoyancy of a metal boat shall be not less than that required above for a wooden boat of the same cubic capacity, the volume of the watertight air-cases and that of the external buoyancy being increased accordingly.

REGULATION XXVI.

Boats of Class II.

Boats of Class II must satisfy the following conditions:—

(a) Open Boats with Internal and External Buoyancy—Upper Part of Sides collapsible.

A boat of this type shall be fitted both with watertight air-cases and with external buoyancy—the aggregate volume of which, for each person which the boat is able to accommodate, shall be at least equal to the following amounts:—

                                                Cubic              Cubic
                                                Decimetres.        Feet.

Air-cases 43 1·5
External buoyancy (if of cork) 6 0·2

The external buoyancy may be of cork or of any other equally efficient material, but such buoyancy shall not be obtained by the use of rushes, cork shavings, loose granulated cork, or any other loose granulated substance, or by any means dependent upon inflation by air.
