Captained by the misanthropic, eccentric war veteran known simply among island locals as Quint, Orca was sunk off the coast of Martha's Vineyard following an extended fishing excursion in the summer of 1973.
On its final voyage, Orca was crewed by Martha's Vineyard chief of police, Martin Brody, and a schooled oceanographer from Woods Hole, Matt Hooper. A game fisherman in every sense, Quint was steadfast as the boats' beleaguered captain to the very end, with machete and blood flying in dramatic recoil.
The demise of the Orca was due in part to structural damage resulting from relentless attacks by a now infamous maniacal rogue shark. Although the boat had been designed to seek out and catch sharks, it was ultimately no match for the overtly cunning, pursuing predator Quint was hired to catch. Attempting to draw the monster in to the shallows, the Orca was eventually over revved and inadvertently scuttled. After listing to port, Brody was able to fire one final explosive shot from the sinking mast at a compressed air tank in the jaws of the attacking shark.
