(2) Gravity davits of types other than that referred to in subsection (1) shall be so designed that there is a positive turning out moment during the whole of the davit travel from the inboard to the outboard position when the vessel is listed up to 25 degrees either way. (3) Where mechanically powered appliances are fitted for the recovery of emergency boats, efficient hand gear shall also be provided.ģ At least two lifelines, each long enough to reach the water under all conditions of draught with the ship listed 15 degrees either way, shall be attached to each davit span.Ĥ Luffing type davits shall be such that the lifeboat in turning-out condition can be turned out against a 15 degree list, and shall have adequate fore and aft stability.ĥ (1) Where gravity type davits comprising arms mounted on rollers that engage with and travel down fixed inclined trackways are employed, the trackways shall be inclined at an angle of not less than 30 degrees to the horizontal when the vessel is upright. (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. (b) luffing or gravity type for a lifeboat weighing not more than 2.29 t in its turning out condition,īut radial davits may be accepted in ships not over 45.7 m in length carrying not more than 12 passengers.
