Set along the shores of Prospect Harbor, 178 Main Street offers a front-row seat to life on the Maine coast. With more than 300 feet of waterfront, a substantial private wharf, float, and mooring, this is a property designed around the water-where mornings begin with boats moving through the harbor and days can be spent exploring the coastline from your own dock. Acadia's Schoodic Peninsula, with miles of hiking trails and natural beauty, is within easy reach, while nearby Winter Harbor offers restaurants, shops, and seasonal ferry service to Bar Harbor. From boating and exploring the Schoodic coast to dinner in the village or simply watching the harbor, 178 Main Street offers an authentic connection to Downeast Maine. Completely renovated in 2026, the 2BR/2BA residence features a light-filled open living space and kitchen with Shaker-style cabinetry, eat-in island, quartz counters, and stainless appliances. The main level includes a large bedroom with private deck access and in-closet laundry, plus a full bath accessible from the bedroom, living spaces, and outdoor living area. Upstairs, the spacious primary takes in ever-changing views of Prospect Harbor and features a spa-inspired bath with dual sinks, soaking tub, separate shower, walk-in closet, and laundry. Outside, the waterfront takes center stage. The wharf, float, and mooring are complemented by a bait house with storage and hoist. Take in views toward the lighthouse, watch the rhythm of the working waterfront, or end the day in the waterfront sauna or hot tub. Extensive improvements include updated electrical and plumbing, heat pumps, on-demand hot water, generator, standing-seam metal roof, board-and-batten siding, and more. A year-round residence, coastal retreat, or investment property defined by the lifestyle that surrounds it.
