Amity Island

Amity is the unofficial name of an Island otherwise known as Martha's Vineyard which lies off the coast of Massachusetts. Amity is the setting for 3 Jaws films in the franchise including 'Jaws', 'Jaws2', and 'Jaws4' (aka Jaws: The revenge).

The Amity Incident (fictional!) 

It has been alleged: 

"The Amity Incident is a frightening series of horrific shark attacks which were later adapted for films and formed what is known more commonly as the JAWS film franchise.

Years after the initial Amity incident, people are still afraid to go into the water which has distinctly affected the Islands summer tourist economy"

In the hopes of playing down the shark attack debacle, the island council has moved to adopt 'Martha's Vineyard' as the island's official name, thereby limiting the use of 'Amity' for occasional events marking the anniversary of the Amity Incident only."

However, this is outright false. First, in point of fact:

    Bartholomew Gosnold, of Falmouth, England, in 1602 sailed for Virginia. Contrary winds drove him to the Azores; thence he sailed a little north of west, and struck out boldly

    across the Atlantic. He was the first Englishman to sail directly to the American coast, thereby saving nearly a thousand miles in distance and at least a week in sailing time. He

    landed on a cape which he named Cape Cod from the abundance of codfish found there. Then doubling the cape and sailing to the southward he landed on a small island

    about six miles southeast of Gay Head. He called this small island Martha's Vineyard. The next day he landed on the larger island. After exploring it and finding it so large,

   well wooded, and with such luxuriant grape vines, many beautiful lakes and springs of the purest water, he transferred the name and called it Martha's Vineyard, in honor of

   his mother whose name was Martha. The other island he named No-Man's-Land.

Secondly, there were no series of shark attacks in Massachusetts. In point of fact a recent shark attack there has caused a stir because it was the first in 76 years. . Google it. look it up. The book Jaws is based on the New Jersey shark attacks . From regular Wikipedia-- Jersey Shore shark attacks of 1916 ' were a series along the coast of New Jersey between July 1 and July 12, 1916, in which four people were killed and one injured.
