For a free-fall lifeboat launching appliance, each launching ramp and its connection to the release mechanism should be tested with a static load of 2.2 times the working load. The appliance should not be deformed or damaged. For free-fall lifeboats it should be demonstrated that the survival craft can be recovered to its stowage position and can be safely and properly secured. It should be demonstrated that adjustable ramps for free-fall launching may be adjusted satisfactorily with the free-fall lifeboat loaded to 1.2 times its related load. The launching appliance shall be designed and arranged so that in its ready to launch position, the distance from the lowest point on the lifeboat it serves to the water surface with the ship in its lightest seagoing condition does not exceed the lifeboat’s free-fall certification height, taking into consideration the requirements of paragraph [url=mk MSITStore:C:\Program%20Files\Lloyd]4.7.3[/url].
4.7.3 Performance requirements 4.7.3.1. Each free-fall lifeboat should make positive headway immediately after water entry and shall not come into contact with the ship after a free-fall launching against a trim of up to 10° and a list of up to 20° either way from the certification height when fully equipped and loaded with: .1. its full complement of persons;
.2. occupants so as to cause the centre of gravity to be in the most forward position;
.3. occupants so as to cause the centre of gravity to be in the most aft position; and
.4. its operating crew only.
4.7.3.2. For oil tankers, chemical tankers and gas carriers with a final angle of heel greater than 20° calculated in accordance with the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto and the recommendations of the Organization [url=mk MSITStore:C:\Program%20Files\Lloyd]see footnote [/url]as applicable a lifeboat shall be capable of being free-fall launched at the final angle of heel and on the base of the final waterline of that calculation.
