This property offers an impressive 42 feet of dockage with a concrete seawall and wooden step-down dock, ready for your big boat and all your water toys. Exceptionally maintained by the same family for over 40 years, this home shows true pride of ownership from the moment you enter the open-concept kitchen, dining and living area.
