3 Automatically Self-Righting Liferafts

  3.1 Except as provided in this section, all automatically self-righting liferafts should comply with the requirements of paragraph 4.1 and, if an inflatable liferaft, with the requirements of paragraph 4.2 or, if a rigid liferaft, with the requirements of paragraph 4.3.

  3.2 The requirements of paragraphs 4.2.5.2 and 4.2.6.2 do not apply to inflatable automatically self-righting liferafts. The requirements of paragraph 4.3.5.1 do not apply to rigid automatically self-righting liferafts.

  3.3 The fully equipped liferaft should automatically turn from a capsized position to an upright position on the surface of the water, regardless of whether it inflates in the inverted position underwater or on the surface of the water or capsizes for any reason following inflation.

  3.4 The floating automatically self-righting liferaft should be fitted with self-draining arrangements. The liferaft should be capable of being safely used at all times by untrained persons.

  3.5 The automatically self-right liferafts do not need to be arranged for easy side-to-side transfer, and are, therefore, not subject to the 185 kg mass limitation of paragraph 4.1.2.2.

  3.6 On ro-ro passenger ships operating on fixed routes in shallow water, the requirement that liferafts be arranged so as to ensure that the liferafts are not dragged under the sinking ship, can be achieved by using a liferaft painter with a length of at least the maximum depth of the water plus an additional 20%.
