Artikel 112

(1) Lifeboats shall be constructed to the satisfaction of the Administration and be of such form and proportions that they shall have adequate freeboard and stability in a seaway when loaded with their full complement of persons and equipment and comply with the provisions of Sections 1 and 2 of Appendix 2, as applicable. Lifeboats loaded with their full complements of persons and equipment shall, when flooded and open to the sea, be capable of keeping afloat with positive stability.
(2) The cubic capacity of a rigid lifeboat shall be determined by the rule given in Section 3 of Appendix 2 or by any other method giving at least the same degree of accuracy. The capacity of a square-sterned lifeboat shall be calculated as if the lifeboat had a pointed stern.
(3) The number of persons which a rigid lifeboat shall be permitted to accommodate shall: (a) be equal to the greatest whole number obtained by dividing the capacity in cubic metres by a factor: (i) of 0.283 for a boat of 7.3 metres in length or over;
(ii) of 0.396 for a boat of 4.9 metres in length; and
(iii) obtained by linear interpolation between 0.396 and 0.283 for boats over 4.9 metres but less than 7.3 metres; and
(i) of 0.283 for a boat of 7.3 metres in length or over;
(ii) of 0.396 for a boat of 4.9 metres in length; and
(iii) obtained by linear interpolation between 0.396 and 0.283 for boats over 4.9 metres but less than 7.3 metres; and
(b) in no case exceed the number of adult persons wearing Iifejackets who can be properly seated without in any way interfering with the use of oars or the operation of other propulsion equipment.
(a) be equal to the greatest whole number obtained by dividing the capacity in cubic metres by a factor: (i) of 0.283 for a boat of 7.3 metres in length or over;
(ii) of 0.396 for a boat of 4.9 metres in length; and
(iii) obtained by linear interpolation between 0.396 and 0.283 for boats over 4.9 metres but less than 7.3 metres; and
(i) of 0.283 for a boat of 7.3 metres in length or over;
(ii) of 0.396 for a boat of 4.9 metres in length; and
(iii) obtained by linear interpolation between 0.396 and 0.283 for boats over 4.9 metres but less than 7.3 metres; and
(b) in no case exceed the number of adult persons wearing Iifejackets who can be properly seated without in any way interfering with the use of oars or the operation of other propulsion equipment.
(4) The number of persons which an inflated lifeboat shall be permitted to accommodate shall be the lesser of the following numbers: (a) the greatest whole number obtained by dividing by 0.12 the volume of the main buoyancy tubes measured in cubic metres reduced by 0.40 cubic metres which for this purpose shall include neither the thwarts nor the centreline tube if fitted; or
(b) the greatest whole number obtained by dividing by 0.32 the area of the floor measured in square metres which for this purpose may include the thwarts and centreline tube if fitted. In no case shall it exceed the number of adult persons wearing lifejackets who can be properly seated without in any way interfering with the use of oars or the operation of other propulsion equipment. No inflated lifeboat shall be approved which has a carrying capacity of less than 10 persons.
(a) the greatest whole number obtained by dividing by 0.12 the volume of the main buoyancy tubes measured in cubic metres reduced by 0.40 cubic metres which for this purpose shall include neither the thwarts nor the centreline tube if fitted; or
(b) the greatest whole number obtained by dividing by 0.32 the area of the floor measured in square metres which for this purpose may include the thwarts and centreline tube if fitted.
