124.—(1) Part I of the Act and so much of Part VI of the Act as relates to contributions and the regulations made under those provisions shall, insofar as they are not inconsistent with the provisions of this Case, apply to mariners with the modification set out in paragraph (2).
(2) The modification is that, where a mariner is, on account of his being at sea or outside Great Britain or Northern Ireland (as the case requires) by reason of his employment as a mariner, unable to perform an act required to be done either immediately or on the happening of a certain event or within a specified time, he shall be deemed to have complied with that requirement if he performs the act as soon as is reasonably practicable, although after the happening of the event or the expiration of the specified time.
