29 CFR § 783.45 - Deductions from wages.
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.
