Amendment 11

  11 Add new sections 7.4, 7.5 and 7.6 as follows:footnote

"7.4 Rigid fast rescue boats

 Rigid fast rescue boats should be subjected to the tests prescribed in 6.2 to 6.13 (except 6.4, 6.5.2, 6.6, 6.7.2, 6.8.1, 6.10.5, 6.10.6, 6.11.1), 6.15 (if a rigid fast rescue boat is self-righting), 7.1.3, 7.2.4.2, 7.2.10, 7.2.11 (if a rigid fast rescue boat is equipped with outboard motor) and 7.2.13 (except that a larger engine is not required in the case of a boat equipped with an inboard engine.)

  7.4.1 Overload test

  • 7.4.1.1 The boat, when suspended by its lifting point, should be loaded with properly distributed load of 4 times the weights to represent the equipment and full complement of persons for which it is to be approved. The weights should be distributed in proportion to the loading of the boat in its service condition, but the weights used to represent the persons need not be placed 300 mm above the seat pan.

  • 7.4.1.2 Testing by filling the boat with water should not be accepted. This method of loading does not give the proper distribution of weight. Machinery may be removed in order to avoid damage, in which case weights should be added to the boat to compensate for the removal of such machinery.

  • 7.4.1.3 The boat and bridle or hook and fastening device should be examined after the test has been conducted and should not show any signs of damage.

  7.4.2 Operation tests

Operation of engine and fuel consumption test

  • 7.4.2.1 The boat should be loaded with weights equal to the mass of its equipment and the number of persons for which the boat is to be approved. The engine should be started and the boat manoeuvred for a period of at least 4 h to demonstrate satisfactory operation. It should be demonstrated that the boat can tow the largest of the ship's liferafts loaded with the number of persons for which it is to be approved and its equipment at a speed of 2 knots.

  • 7.4.2.2 The boat should be run at a speed of not less than 8 knots with a full complement of persons and equipment and 20 knots with a crew of 3 persons for a period which is sufficient to ascertain the fuel consumption and to establish that the fuel tank has the required capacity.

  7.4.3 Righting test (if rigid fast rescue boat is not self-righting)

It should be demonstrated that both with and, in the case of an outboard engine, without engine and fuel or an equivalent mass in place of the engine and fuel tank, the rigid fast rescue boat is capable of being righted by not more than two members of its crew if it is inverted on the water.

7.5 Inflated fast rescue boats

 Inflated fast rescue boats should be subjected to the tests prescribed in 6.3, 6.5.1, 6.7.1, 6.8.2, 6.10.1 to 6.10.4, 6.11 (except 6.11.1), 6.12, 6.13, 6.15 (if inflated fast rescue boat is self-righting 7.1.3, 7.2.2 to 7.2.11 (if inflated fast rescue boat is equipped with outboard motor), 7.2.12 (if inflated fast rescue boat is not self-righting),7.2.13 to 7.2.19 and 7.4.2.

7.6 Rigid/inflated fast rescue boats

  7.6.1 Rigid/inflated fast rescue boats should be subjected to the tests prescribed in 6.2 (for hull), 7.2.17 (for inflated part), 6.3, 6.5.1, 6.7.1, 6.8.2, 6.10.1 to 6.10.4, 6.11 (except 6.11.1) to 6.13, 6.15 (if rigid/inflated fast rescue boat is self-righting), 7.1.3, 7.2.2 to 7.2.11 (if rigid/inflated rescue boat is equipped with outboard motor), 7.4.3 (if rigid/inflated fast rescue boat is not self-righting), 7.2.13 (except that a larger engine is not required in the case of a boat with an inboard engine), 7.2.14, 7.2.18, 7.2.19, 7.4.1 and 7.4.2.

  7.6.2 The tests prescribed in 7.2.8, 7.2.9 and 7.2.18 do not apply to rigid/inflated fast rescue boats if the boat has its waterline below the lower side of the inflated tube."
