Sea letter, also known as a letter of marque, is a legal document authorizing a ship owner to attack enemy vessels. Synonyms for sea letter include letter of marque and reprisal, privateering permit, commission, and naval certificate. These documents were commonly used during times of war or conflict, allowing private ships to engage in attacks on enemy vessels without being considered pirates.
