5.1.3 Additional requirements for inflated rescue boats

  5.1.3.1 The requirements of paragraph 4.4.1.4 and 4.4.1.6 do not apply to inflated rescue boats.

  5.1.3.2 An inflated rescue boat shall be constructed in such a way that, when suspended by its bridle or lifting hook:

  • .1 it is of sufficient strength and rigidity to enable it to be lowered and recovered with its full complement of persons and equipment;

  • .2 it is of sufficient strength to withstand a load of 4 times the mass of its full complement of persons and equipment at an ambient temperature of 20 ± 3°C, with all relief valves inoperative; and

  • .3 it is of sufficient strength to withstand a load of 1.1 times the mass of its full complement of persons and equipment at an ambient temperature of -30°C, with all relief valves operative.

  5.1.3.3 Inflated rescue boats shall be so constructed as to be capable of withstanding exposure:

  • .1 when stowed on an open deck on a ship at sea;

  • .2 for 30 days afloat in all sea conditions.

  5.1.3.4 In addition to complying with the requirements of paragraph 4.4.9, inflated rescue boats shall be marked with a serial number, the maker's name or trade mark and the date of manufacture.

  5.1.3.5 The buoyancy of an inflated rescue boat shall be provided by either a single tube subdivided into at least five separate compartments of approximately equal volume or two separate tubes neither exceeding 60% of the total volume. The buoyancy tubes shall be so arranged that the intact compartments shall be able to support the number of persons which the rescue boat is permitted to accommodate, each having a mass of 82.5 kg, when seated in their normal positions with positive freeboard over the rescue boat's entire periphery under the following conditions:

  • .1 with the forward buoyancy compartment deflated;

  • .2 with the entire buoyancy on one side of the rescue boat deflated; and

  • .3 with the entire buoyancy on one side and the bow compartment deflated.

  5.1.3.6 The buoyancy tubes forming the boundary of the inflated rescue boat shall on inflation provide a volume of not less than 0.17 m 3 for each person the rescue boat is permitted to accommodate.

  5.1.3.7 Each buoyancy compartment shall be fitted with a non-return valve for manual inflation and means for deflation. A safety relief valve shall also be fitted unless the Administration is satisfied that such an appliance is unnecessary.

  5.1.3.8 Underneath the bottom and on vulnerable places on the outside of the inflated rescue boat, rubbing strips shall be provided to the satisfaction of the Administration.

  5.1.3.9 Where a transom is fitted it shall not be inset by more than 20% of the overall length of the rescue boat.

  5.1.3.10 Suitable patches shall be provided for securing the painters fore and aft and the becketed lifelines inside and outside the boat.
