The subject of this article:
Jenny is the name given to a shrimping boat purchased by Forrest Gump from an old black shrimp fisherman, the first of the fleet of ships for the Bubba Gump Shrimp Company. He named it after the love of his life, Jenny Curran. Shrimping is initially hard and unproductive for Forrest, until Hurricane Carmen runs through Bayou La Batre, leaving Jenny the one surviving shrimping boat.
The boom in business following the hurricane's destruction of the competition meant that Forrest's company was able to acquire more boats: he says at the bus stop in Savannah, Georgia that he has "twelve Jennys".
While Forrest enters the shrimping business in the novel, and owns shrimping boats, it is only in the film that any boat is shown to be named "Jenny".
