Section 2 of the Act creates the offence of piracy with violence:
Whosoever, with intent to commit or at the time of or immediately before or immediately after committing the crime of piracy in respect of any ship or vessel, shall assault, with intent to murder, any person being on board of or belonging to such ship or vessel, or shall stab, cut, or wound any such person, or unlawfully do any act by which the life of such person may be endangered, shall be guilty of felony...
(a) any illegal acts of violence or detention, or any act of depredation, committed for private ends by the crew or the passengers of a private ship or a private aircraft, and directed—
(i) on the high seas, against another ship or aircraft, or against persons or property on board such ship or aircraft;
(ii) against a ship, aircraft, persons or property in a place outside the jurisdiction of any State;
(b) any act of voluntary participation in the operation of a ship or of an aircraft with knowledge of facts making it a pirate ship or aircraft;
(c) any act of inciting or of intentionally facilitating an act described in subparagraph (a) or (b).
Article 102
Piracy by a warship, government ship or government aircraft whose crew has mutinied
The acts of piracy, as defined in article 101, committed by a warship, government ship or government aircraft whose crew has mutinied and taken control of the ship or aircraft are assimilated to acts committed by a private ship or aircraft.
Article 103
Definition of a pirate ship or aircraft
A ship or aircraft is considered a pirate ship or aircraft if it is intended by the persons in dominant control to be used for the purpose of committing one of the acts referred to in article 101. The same applies if the ship or aircraft has been used to commit any such act, so long as it remains under the control of the persons guilty of that act.
