Cuttyhunk Island is the outermost island in the Elizabeth Islands chain. It’s also a public island. Cuttyhunk Marina, located on the banks of Cuttyhunk Pond, is the most popular place to moor, dock, or launch your boat on the island. This saltwater pond connects to Cuttyhunk Harbor in Buzzards Bay via a narrow east-west channel on the northeastern tip of Cuttyhunk Island.
