In this section, the term “experimental vessel” means a vessel owned by the United States Government (including a vessel in the National Defense Reserve Fleet) that has been constructed, reconditioned, or remodeled for experimental or testing purposes.

The Secretary of Transportation, for the purpose of practical development, trial, and testing, may operate an experimental vessel under a bareboat charter or general agency agreement in the foreign or domestic trade of the United States or for use for the account of a department or agency of the Government, without regard to other provisions of this subtitle and other laws related to chartering and general agency operations. Not more than 10 vessels may be operated and tested under this section in any one year.

Operation of a vessel under this section shall be on terms the Secretary considers appropriate to carry out the purposes of this subtitle. A bareboat charter under this section shall be at reasonable rates and include restrictions the Secretary considers appropriate to protect the public interest, including provisions for recapture of profits under section 57517 of this title. A charter or general agency agreement under this section shall be reviewed annually to determine whether conditions exist to justify continuance of the charter or agreement.

A seaman engaged in vessel operations of the Secretary under this section and employed through a general agent in connection with a charter or agreement under this section is entitled to all the rights and remedies provided in sections 1(a) and (c), 3(c), and 4 of the Act of March 24, 1943 (50 U.S.C. 4701(a), (c), 4703(c), and 4704).
