(1) which is used at any time after the one-year period beginning on the effective date of such regulations for activities pursuant to this subchapter and which is built or rebuilt at any time after such one-year period, when required to be documented by the laws of the United States, be documented under the laws of the United States;

(2) which is used for activities pursuant to this subchapter, comply, except as provided in subsection (b), with such minimum standards of design, construction, alteration, and repair as the Secretary or the Secretary of the Department in which the Coast Guard is operating establishes; and

(3) which is used at any time after the one-year period beginning on the effective date of such regulations for activities pursuant to this subchapter, be manned or crewed, except as provided in subsection (c), by citizens of the United States or aliens lawfully admitted to the United States for permanent residence.

The regulations issued under subsection (a)(3) of this section shall not apply—
