The Royal American(1927)

Story of a young shanghaied sailor. Forced to work as a deckhand on a rough-and-tumble transport vessel, the sailor ends up in South America, where his brutish captain intends to sell guns and ammo to a band of revolutionaries. Besting the villains, Jack gets into the thick of things himself, ultimately rescuing the heroine -- likewise "shanghaied" by the captain -- from Certain Doom.
