$14 Million Peninsula Estate in Maine Feels Like It’s Floating in the Middle of the Ocean

A plum waterfront location is one of the most sought-after amenities on the market, particularly when it comes to the beautiful Maine coastline—but finding a home that features a staggering 3,000 feet of private frontage across three sides is almost unheard of.

Yet that is exactly what is on offer in Yarmouth, thanks to a newly listed $14 million estate that is tucked away at the heart of a private peninsula overlooking Dead Man's Cove.

The property, which is listed with Anna Charlotte of Legacy Properties Sotheby's International Realty, stretches across 7.1 acres into Casco Bay, boasting more than 3,000 feet of private shoreline and an exceptionally secluded setting that's just 30 minutes from downtown Portland.

The listing images reveal a jaw-dropping glimpse into the kind of extraordinary lifestyle that can be enjoyed on the property—while the description paints an equally compelling picture of mornings spent watching the mists clear across the water as the gentle flow of the tide provides an idyllic soundtrack to your first coffee of the day.

"As the sun rises over Casco Bay, islands emerge through the morning mist and the day slowly comes to life," it begins. "Eagles soar across the bay while a lobsterman works quietly on the water and a paddleboarder drifts along the shoreline. Watching the sun rise over Casco Bay, it is easy to understand why Maine has long been called the Land of Dawn."

Surrounded by water on almost every side, save for the small stretch that connects it to the mainland, the peninsula estate is characterized by ancient oaks and winding footpaths that lead to sandy beaches, rocky ledges, and quiet coves ideal for swimming or launching a kayak.

At the heart of the property is a 7,592-square-foot coastal residence overlooking the bay. Built in 2005, the four-bedroom, six-bathroom home was designed to maximize its waterfront setting, with sweeping views visible from nearly every room.

The interiors lean classically cozy, with custom stone, marble, and wood finishes throughout. Four fireplaces anchor the main living spaces, while a gourmet kitchen includes both prep and catering kitchens.

Additional amenities include an elevator, a heated four-car garage, and a multifuel heating system designed for year-round living.

The outdoor amenities are just as—if not more—impressive.

A deepwater dock provides access to Casco Bay at all tides, allowing owners to spend the day island hopping, dropping anchor in secluded coves, or cruising into Portland by boat. Also included is a timber-frame barn that could serve as storage or a studio space.

The estate's beaches lend themselves to quintessential Maine summers—building sandcastles, gathering around a shoreline bonfire, or simply watching the sun set over the bay.

"Sweeping water views in every direction create the kind of place where life's most meaningful moments seem to find their way and a family legacy is built for generations to come," the listing states.

Despite its seemingly remote location, the dwelling is actually very conveniently located for those who are perhaps looking for a weekend or summer retreat, with the nearest jetport just a 30-minute drive away.

Should the peninsula's own beaches not be enough, there are also a plethora of other options nearby, while the adjacent Cousins Island offers an array of nature trails and hiking paths.
