Gross and net 
tonnages. 
"(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 ad-
measured 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 IT.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 law-
enacted 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
