 So in original. Probably should be “willful”.
In subsec. (f)(1), “section 60105 of title 46” substituted for “section 4197 of the Revised Statutes of the United States (46 App. U.S.C. 91)” on authority of Pub. L. 109–304, § 18(c), Oct. 6, 2006, 120 Stat. 1709, which Act enacted section 60105 of Title 46, Shipping.

Subsec. (b)(2). Pub. L. 101–380, § 4302(j)(2), which directed the substitution of “commits a class C felony.” for “shall, in lieu of the penalties prescribed in paragraph (1), be fined not more than $100,000, or imprisoned for not more than 10 years, or both.”, was executed by making the substitution for “shall, in lieu of the penalties prescribed in paragraph (1), be fined not more than $100,000, or imprisoned for not more than ten years, or both.”
