By Act of Congress approved June 24, 1910, 36 St. at L. 629, it is provided that it shall be unlawful for any oceangoing steamer, whether American or foreign, carrying passengers and carrying fifty or more persons, including passengers and crew, to leave any port of the United States unless equipped with efficient apparatus for radio communication in good working order, capable of communicating over a distance of at least one hundred miles, night or day, and in charge of a competent operator. To be efficient the apparatus must be capable of exchanging messages with stations using other systems of radio communication. A fine of not more than $5,000 is assessed against the master or other person in charge for violation of the act and as has been said (§ 5 supra) the fine is a lien upon the ship. Regulations for the enforcement of the act are made by the Secretary of Commerce. The act does not apply to steamers plying between ports less than 200 miles apart.
12. Failure to Disclose Liens.—
By the Ship Mortgage Act, 1920 (see Appendix, Merchant Marine Act, Sec. 30), a mortgagor of a preferred mortgage is required, upon request of the mortgagee, to disclose the existence of any maritime lien, prior mortgage or other liability upon the vessel, known to the mortgagor, and to refrain, until the mortgagee has had an opportunity to record the mortgage, from incurring liens upon the vessel except for wages, general average and salvage. Disobedience to this injunction with intent to defraud is made a misdemeanor punishable by a fine of not more than $1,000 and imprisonment of not more than two years, or both, and the mortgage debt is to become due immediately.
13. Mutiny.—
This term is most often used with reference to an offense committed on shipboard, although technically it is not peculiar to shipping, but may be committed by soldiers and servants. Mutiny on shipboard is defined as follows: "A revolt or mutiny consists in attempts to usurp the command from the master or to deprive him of it for any purpose by violence or in resisting him in the free and lawful exercise of his authority; the overthrowing of the legal authority of the master, with an intent to remove him against his will and the like." Mere refusal of duty or disobedience by a seaman while liable to punishment by the master is not mutiny, and the conduct may be very aggravating and contumacious without amounting to mutiny.

CHAPTER XV
WRECKS AND DERELICTS
1. Definitions.—
In a legal sense, the word wreck includes ships and cargoes, or any parts thereof, which have been cast on shore by the sea, and derelict applies to similar property abandoned on the sea. The terms should be understood as limited to things of a maritime nature and as including the old subdivisions of flotsam, jetsam and ligan,—flotsam being the name for the goods which float when the ship is sunk, jetsam meaning those which are jettisoned or thrown overboard, and ligan those cast into the sea but tied to a buoy or marker so that they might be found again. Derelict is the term applied to a thing which is abandoned at sea by those who were in charge of it, without any hope of recovery or intention of return.
