PART IRequirements for Existing Ships

General

• 1 For the purposes of this Schedule, in relation to a lifeboat or life raft,

  turning-out condition

  turning-out condition means a lifeboat or life raft that is fully equipped but manned only by its launching crew; (état de mise à l’eau sans passagers)

  working load

  working load and loaded condition mean the sum of the weight of the lifeboat or life raft, equipment, blocks and falls, and the number of persons with which the lifeboat or life raft is required to be lowered, each person being considered to weigh 75 kg. (charge pratiqueoucharge complète)

    • (a) gravity type for a lifeboat weighing more than 2.29 t, or

    • (b) luffing or gravity type for a lifeboat weighing not more than 2.29 t in its turning out condition,

    but radial davits may be accepted in ships not over 45.7 m in length carrying not more than 12 passengers.

  • (2) Lifeboats weighing more than 2.29 t in loaded condition shall be served by steel wire rope falls together with winches, but alternative arrangements may be accepted in existing ships, and emergency boats shall be rapidly recoverable.
