Today, Dark Harbor Boat Yard has evolved into a full service boat yard, located at the mouth of Penobscot Bay, in Cradle Cove on 700 Acre Island. “Acre Island,” as it is referred to, sits off of Islesboro, next to Warren Island (which has its own state park).

Although there is no automobile access to Acre Island, Islesboro can be reached by the Maine State Ferry, the Margaret Chase Smith, that provides multiple departures from Lincolnville daily. Arrangements can be made to meet you at the Islesboro Ferry Dock and then a quick boat ride delivers you to Acre Island.

For those arriving by water, Cradle Cove can be a safe anchorage within Gilkey Harbor, as you explore the area. Besides offering fuel, moorings, and any repair needed; we also have showers, laundry, ice and a fully stocked marine store.

Along with the above-mentioned Dark Harbor 20's, we service between 200-250 boats ranging from working lobster boats to ocean cruisers. We have an extensive dry-stack storage area for small powerboats, sailboats and dinghies; while the larger yachts are hauled on a railway and stored under cover.

We have extensive shops for varnish and paint work, outboard maintenance, gas/diesel engine maintenance, carpentry repairs and fiberglass repairs In years past, we've built boats from the keel up, refastened entire Dark Harbor 20's, reconstructed sailing yachts, and maintained many a boat.
