Beyond Comparison...This iconic and storied waterfront compound, "Beam Ends", located in Monomoy; where the view lines are endless. One can enjoy a front row seat to Nantucket Harbor with the sea life of sailboats, fishing boats, paddle boarding and picnic boats dotting the harbor offering the best of what Nantucket has to offer. Complete privacy can be expected as the almost 4 acre property is surrounded by vast conservation lands and the idyllic Nantucket "Creeks" for nearly a mile. Direct beach & water access along a private path is for the most discerning of buyers.
