If any amount which, under subsection (1)(a) or (2) above, is payable to a seaman is not paid at the time at which it is so payable the seaman shall be entitled to wages at the rate last payable under the crew agreement for every day on which it remains unpaid during the period of 56 days following the time of discharge; and if any such amount or any amount payable by virtue of this subsection remains unpaid after the end of that period it shall carry interest at the rate of 20 per cent. per annum.

Where the crew agreement referred to in subsection (1) above provides for the seaman’s basic wages to be payable up-to-date at specified intervals not exceeding one month, and for any additional amounts of wages to be payable within the pay cycle following that to which they relate, any amount of wages due to the seaman under the agreement shall (subject to subsection (5) below) be paid to him not later than the date on which the next payment of his basic wages following the time of discharge would have fallen due if his employment under the agreement had continued.

If it is not practicable, in the case of any amount due to the seaman by way of wages additional to his basic wages, to pay that amount by the date mentioned in subsection (4) above, that amount shall be paid to him not later than what would have been the last day of the pay cycle immediately following that date if his employment under the crew agreement had continued.

If any amount which, under subsection (4) or (5) above, is payable to a seaman is not paid at the time at which it is so payable, it shall carry interest at the rate of 20 per cent. per annum.
