One-of-a-kind opportunity in the heart of Casco Bay to own 5.36 acres of land with structures and 5.91 acres of SUBMERGED LAND. Boasting breathtaking daytime views and stunning sunsets, this property is comprised of three contiguous tax lots on the west end of Long Island. The waterfront lot features approximately 2.35 acres with 750' shore frontage, a 110' wharf on pilings, and a 435' stone breakwater. Set on 3.01 acres, the upland lot offers sweeping views of Casco Bay with an 11,000 SF, 2 story building formerly used as navy barracks . The submerged land lot, known as 'the small boat pool' by the Navy, is approximately 5.91 acres between the breakwater and the shoreline and provides ample opportunity to further develop the existing wharf as well as potential uses for a marina, aquaculture site or other development. Just minutes from the public ferry and water taxi dock, this spectacular property is graced with the beauty and serenity of island life while being a short boat ride from the lively Portland waterfront.
