This is a tale of the competition between Consuelo(Gianna Canale): daughter of a retiring successful pirate captain, and William(Anthony Steel): one of his crew, and Consuelo's boyfriend, to succeed the old man as captain of the Santa Maria. The competition begins with William's victory over another man, in a sword duel, then Consuelo's victory over William. No one challenged her, so she was declared the new captain. It's also the story of the ambition of Anne, Duchess of a Spanish principality, and her retainer: Robert, together and separately, to steal a fortune in booty, hidden by the old captain, whose location was known only by the dead captain, Consuelo, and William..... The film was produced by an Italian concern, directed by Luigi Capuano, who earlier had directed the rather similar "Queen of the Pirates", also starring the beautiful Gianna Canale. I'm also familiar with the Hollywood films "Anne of the Indies" and "Against All Flags", which also feature a tigress as a pirate captain......If you're looking for a classic sea battle or 2 between a pirate ship and it's prey, this isn't the right film. There are several massive battles between the pirates and the Spanish, but they are either on land, or between Spanish and pirates already on the same ship. After Consuelo was decreed the new captain, her father:' The Tiger of the Sea' was knifed in the back, dying. The knife was identified as belonging to William, hence he was the assumed murderer, perhaps disappointed that he wasn't chosen the new captain. He was about to be sentenced to death when a horde of Spanish soldiers overran the pirates on land. William and a few other pirates ran toward the Santa Maria, and sailed off. Consuelo and a few other pirates also escaped, but missed the Santa Maria Thus, Consuelo had 2 big reasons to catch William and the Santa Maria. had two . They rowed a small boat out to sea. Soon, an armed Spanish ship was sighted. Next thing we know, Consuelo and the others were on that ship(How did they board her?), and soon staged a rebellion, taking over the ship, which became Consuelo's pirate ship. Soon, she attracted more men, and became known as the Tigress of the Seven Seas, as her ship was quite successful in subduing prey. Eventually, the Santa Maria came close, but William raised the white flag. He came on board to parlay with Consuelo, convincing her that he was not the murderer of her father, despite the damning physical evidence. He also said he meant to turn over the Santa Maria to Consuelo. However, this didn't happen immediately, instead they got caught up in an attack on Anne's castle, where the murderer of Consuelo's father was though to be......I will skip over the details of the adventures in and around Anne's castle. I will say, that, surprisingly, Anne achieved her ambition. Consuelo also achieved her goal of killing the murderer of her father(whom you should recognize). As to whether she achieved her goal of making peace with William, finally becoming captain of the Santa Maria, the film leaves us hanging, as they bicker. A reasonable solution to the conflict as to who would command the Santa Maria would have been to have Maria continue captaining her very successful Spanish ship, with the two ships forming a team......See it at YouTube

"Tiger of the Seven Seas" tells the story of Consuelo (Gianna Maria Canale), daughter of a pirate captain everybody calls "The Tiger" (Carlo Ninchi). The old man wants to retire because the crew does not completely trust his abilities anymore. But to whom shall he give the ship? He has no son, and several men are fighting for the leadership already. Then his daughter asks: "why shouldn't a woman become captain?", and thus she gets into a lot of trouble, especially when her father is murdered and cannot help her anymore.Quite nice, but not really something special! "Tiger of the Seven Seas" is a work of experienced director Luigi Capuano who made 2 Sandokan movies with Ray Danton, "The Lion of St.Mark" also with la Canale and "Zorro and the Three Musketeers". A few shots from "The Lion of St.Mark" are used again here which shows the budget limitation. However, with a good deal of treason and fights, this is perfectly alright for a Sunday afternoon.
