Where deductions are made from the wages of a seaman subject to
section 6(b) of the Act, consideration must be given as to whether or
not such deductions are permitted to be made when they result in the
seaman receiving cash wages which are less than the applicable minimum
wage rate for each hour actually on duty during the period covered by
the wage payments. Such considerations are to be based upon the
principles and interpretations governing such deductions. These are set
forth and discussed in part 531 of this chapter. The methods of paying
the compensation required by section 6 and the application thereto of
the provisions of section 3(m) of the Act, which are set forth and
explained in the said part 531, are applicable to seamen subject to the
minimum wage provisions of the Act.
