About This Home
Make summer memories at this seasonal cottage overlooking an expansive 1000+/- feet of waterfront along the East Penobscot Bay and with views extending towards Castine and Cape Rosier. The property includes a main cottage and a guest cottage that can also function as a boathouse. As if taken right off a sailing yacht, the open timber frame main cottage is efficient, comfortable, tastefully finished, and has the charm of being on a ship moored in a harbor. The galley kitchen offers ample storage and essential appliances for a summer feast. This sweet cottage also includes a living area, a bedroom with a closet, and a surprisingly roomy bathroom with a portable toilet. The waterside of the main cottage has floor-to-ceiling sliding glass doors to maximize the view, no matter the forecast. The sleeping loft features a porthole window and a banister reminiscent of a ship's stern rail. The deck has plenty of space for outdoor living and storage for small watercraft, and it is accompanied by an outdoor shower with on-demand hot water. The guest cottage/boat house has a king-size Murphy-style bed, its own bathroom with a composting toilet, and a sliding barn door for launching and storing small boats. The kitchen sink and both bathroom sinks have manual foot pumps to provide water. The property is mostly rocky coastline, inviting you to explore and beachcomb. A place to relax and enjoy the Maine summer with simplicity. Nearby public walking trails extend the outdoor space for exploring nature.
