The Harpswell Islands

Service Beyond the Bridges Stretching from the mainland out to the tips of Orr’s and Bailey Island, our reach is as deep as the coastal waters. We understand the unique challenges of island living, from the salt air’s impact on equipment to the precision needed to cross the Cribstone Bridge. Whether you’re in Cundy’s Harbor or North Harpswell, we ensure your fuel is delivered on time, every time.

Serving Our Coastal Peninsulas

The Anchor of the Harbor From the busy waterfront of Boothbay Harbor to the quiet, winding roads of Southport and East Boothbay, we are the region’s trusted partner for year-round comfort. Navigating the tight drives and coastal exposure of the peninsula requires local expertise—and we’ve been the anchor of reliability here for generations.
