178 Main St

Gouldsboro, ME 04607

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 just as easily be spent exploring the coastline from your own dock. Beyond the property, Acadia’s Schoodic Peninsula, with its 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 staying home and watching the harbor, 178 Main Street offers an authentic connection to Downeast Maine. Completely renovated in 2026, the two-bedroom, two-bath residence pairs a fresh, thoughtfully updated interior with the character of its working-harbor setting. Upon entry, you will find a light-filled open living space that flows into a thoughtfully designed kitchen with Shaker-style cabinetry, an eat-in island, quartz counters, and stainless steel appliances. The main level features a large bedroom with private deck access and in-closet laundry, plus a full bath thoughtfully positioned for access from the bedroom, main living spaces, and outdoor living area. Upstairs, the spacious primary bedroom takes in ever-changing views of Prospect Harbor and features a private, spa-inspired bath with dual sinks, a soaking tub, a separate shower, and a walk-in closet with laundry. Outside, the waterfront takes center stage. The private wharf, float, and mooring are complemented by a bait house with storage and hoist, creating waterfront infrastructure rarely found with a residence of this scale. Take in views across Prospect Harbor toward the lighthouse, watch the rhythm of the working waterfront, or end the day in the harbor-side sauna or hot tub as the light changes over the water. Extensive improvements include updated electrical and plumbing, three heat pumps, on-demand hot water, a whole-property backup generator, a standing-seam metal roof, board-and-batten siding, exterior stonework, and updated lighting. With a history as a successful short-term rental and the flexibility to serve as a year-round residence, coastal retreat, or investment property, this opportunity is defined not simply by the home, but by the lifestyle that surrounds it.
