Tanker Lifeboats shall be such as are capable of rapid embarkation of all the crew into them when attached to davits, and of being safely lowered and then accurately cleared from the ship's side under the control of the crew inboard, in condition of fire on the surface of the water. We have developed a lifeboat lowering apparatus to meet the requirements, the principal features of which are as follows: (1) The operation to release the lifeboat fully loaded from its stowed position, and to lower it are effected at the crew's will by regulating the boatfalls with pulley brakes or compressor wedges; (2) By adopting a proper radius ratio for the differential boatfall drums fitted to the boat-winch, the checking force to be applied to the falls can be fairly reduced. We actually constructed a prototype apparatus, and carried out several performance tests on it.
