Cohassett Beach is a historic part of the community of Westport. At the turn of the century, Cohassett Beach was a summer artists retreat and a few of the original homes remain however accretion of the beach to the west has altered the "oceanfront" aspect of that neighborhood. There is currently no physical area defined as Cohassett Beach however there is a new sub-division near the original that is named Cohasset Beach offering oceanfront and view homes. None of the census info listed before applies.
