Paragraph 5
Operation.
Every liferaft launching appliance shall be so designed that the liferaft when loaded with its full complement of persons and equipment can be safely lowered into the water.
The speed of lowering of the liferaft shall be automatically controlled at not less than 18 metres per minute nor more than 36 metres per minute and the descent of the liferaft shall be at all times under the manual control of the operator.
Operation of the launching appliance shall not be solely dependent on the use of means other than manual effort or gravity. The arrangements shall be such that the liferaft can be lowered by gravity.
Arrangements shall be such that on becoming waterborne the liferaft shall be automatically released from the launching appliance, and there shall be provision for the manual release of the liferaft by a person on board the liferaft.
When liferaft launching appliances incorporate winches, the winches shall be constructed in accordance with paragraph 10 of Part II of Schedule 15 to these Rules.
