[80 STAT.

"(b) Subject to the owner's option to have his vessel admeasured under subsection (c) of this section, a vessel which is intended to be used exclusively as a pleasure vessel shall be assigned gross and net tonnages which are the product of its length, breadth, and depth in feet and appropriate coefficients. The Secretary of the Treasury shall prescribe the manner in which the length, breadth, and depth shall be measured and the appropriate coefficients to be applied, taking due account of variations in vessel construction, to the end that, taken as a group and so far as practicable, the resulting gross tonnages shall reasonably reflect the relative internal volumes of the vessels admeasured and the resulting net tonnages shall be in the same ratio to the corresponding gross tonnages as the net and gross tonnages of comparable vessels if admeasured under subsection (c) of this section. "(c) A vessel not admeasured under subsection (b) of this section, or a vessel admeasured under subsection (b) which is thereafter to be documented for use other than exclusively as a pleasure vessel, shall be admeasured as prescribed in sections 4150, 4151, and 4153 of the Revised Statutes, as amended (46 U.S.C. 74, 75, 77). " (d) Whenever a vessel documented under the laws of the United States undergoes a change afi^ecting tonnage, or its owner or the Secretary of the Treasury alleges error in its tonnage, it shall be readmeasured to the" extent necessary and i's tonnage redetermined under this section. "(e) The tonnage of a vessel for which a document or certificate of record has been issued before the effective date of this subsection need not be redetermined solely because of amendments to Federal lawenacted at the same time as this subjection; but if it is eligible for admeasurement under subsection (b) of this section its owner shall have the option of having it readmeasured under that subsection. "(f) The Secretary of the Treasury shall ma]'e such regulations as may be necessary to carry out the provisions and intent of this section and of sections 4149, 4150, 4151, and 4153 of the Revised Statutes, as amended (46 U.S.C. 72,74,75,77)."
