For the first time in generations, this extraordinary Pleasant Bay compound–featuring the iconic Topside main residence and the charming two-bedroom Boathouse–is offered as a rare, legacy waterfront estate. With a deep-water dock, moorings, and direct access to the bay, the property delivers a front-row seat to the rhythms of Pleasant Bay and boundless recreation potential. Both homes enjoy sweeping 270-degree views across the water to Eastward Ho, the Chatham Yacht Club, and the Atlantic beyond. Topside offers 5 bedrooms and 4.5 baths with timeless coastal character and spaces designed for gathering, while the Boathouse sits just above the shoreline, featuring 2 bedrooms, 1 bathroom, and its own deck for quiet moments by the sea. A secluded garden patio and broad waterfront lawn offer a blend of intimacy and scale. With a strong rental history and immense potential for expansion or personalization, this is a lifestyle property that invites multigenerational living, savvy investment, or a private retreat. A once-in-a-lifetime opportunity to own one of Cape Cods most storied waterfront settings.
