Luckse Sound is a sound in Casco Bay, Maine, United States. Located between Long Island and Cliff Island, it is one of the deepest channels which separate inner Casco Bay from its outlying waters in the Gulf of Maine, after Portland Channel, Hussey Sound and Broad Sound.Ships were torpedoed in the sound during World War II.Today, the Casco Bay Mailboat passes through the sound.

Hope Island is a privately owned island in Casco Bay near the city of Portland, Maine, United States. It is a part of the Town of Chebeague Island, in Cumberland County. The 89-acre (36 ha) island was considered for an LNG terminal. Developer John Cacoulidis and his wife Phyllis bought the island in 1993. In addition to the existing 10,000 sq. ft. house built in 1913 with nine bedrooms, seven bathrooms and five fireplaces, the Cacoulidises built there a separate 3,300-square-foot guest house, a boathouse with an apartment, and roads looping the island. They've also erected horse stables, a chicken coop, a garage and their own church, and for access both a boat dock and a helicopter pad. In a dispute over property taxes, the two part-time residents attempted but failed in a legislative effort to secede from the town of Cumberland.

Little Chebeague Island is an uninhabited island in Casco Bay, an inlet of the Gulf of Maine, United States. It is located around 0.85 miles (1.37 km) west of the southern tip of the larger Great Chebeague Island. As its name implies, the two are connected—by a sand bar which appears at low tide.The island, which was the home of the Wabanaki people, is co-managed by the Maine Bureau of Parks and Lands (BPL) and the Maine Island Trail Association (MITA) as an undeveloped park where picnicking, camping and swimming are permitted.Being that there are many fresh-water underground springs and rivulets, low-tide exposed sandy areas, such as the sandbar or coves, often have "quicksand" zones that must be noted with caution. The island, which is approximately 0.75 miles (1.21 km) long (east to west) and 0.40 miles (0.64 km) wide (north to south), with 86 acres (35 ha) of land, is mostly dense shrub and forest, having been allowed to grow wild between the end of World War II and the late 20th century. The island now contains around 1.5 miles (2.4 km) of hiking trails, which pass the remains of several former summer cottages.

Chebeague Island is located in Casco Bay, an inlet of the Gulf of Maine. It was originally used as a fishing ground by Abenaki Native Americans. Also known as Great Chebeague (pronounced "sha-big") Island, today it is a town in Cumberland County, Maine, United States. It is located 10 miles (16 km) northeast of Portland, Maine. Chebeague Island is the largest island in Casco Bay that is not connected to the mainland by a bridge. The largest island is Sebascodegan, or "Great Island," which is part of the Town of Harpswell and connected to the mainland via a 100ft bridge. Chebeague Island is one of the twelve major islands of the Calendar Islands, a term that originated in 1700 with the report by the English military engineer Wolfgang William Römer, who claimed there were "as many islands as there are days in the year." As a corrective, the Maine State Historian Robert M. York stated there are "little more than two hundred islands" in Casco Bay.Chebeague Island was a part of the Town of Cumberland until July 1, 2007, when it seceded and became the Town of Chebeague Island. The Town of Chebeague Island includes seventeen islands and their adjacent waters. These include the islands of Bangs, Bates, Hope, Ministerial, Sand, Stave, Stockman, and the tiny Upper Green Islands. At the 2020 census, the town's year-round population was 396. The population is said to more than triple in the summer months. Chebeague Island is part of the Portland–South Portland–Biddeford, Maine Metropolitan Statistical Area.

The Chebeague Island Inn is located on Chebeague Island, Maine, United States. Situated in 2.5 acres (0.0039 sq mi), on South Road, near the northern tip of the island, the inn overlooks part of Casco Bay. Just beyond the western edge of the inn's property, Stone Wharf Landing is where the Chebeague Island Ferry, which runs to and from Cousins Island, berths on the island. The inn also overlooks a few holes of the island's nine-hole golf course. The inn, which has twenty-six rooms, was built in the 1880s, and was originally known as the Hillcrest Hotel. The inn burned down in the early 20th century and was rebuilt in the 1920s. It was given its current name in 2000, and was fully renovated in 2004. It is open between May and October.

Wyman Power Station (known colloquially as CMP) is an oil-fired power station in Yarmouth, Maine, United States. Situated on the town's Cousins Island, the facility was completed in 1957. It is named for William Frizzell Wyman, the former president of Central Maine Power (CMP) and the son of its co-founder, Walter Scott Wyman.The facility has four steam turbine units, the most recent of which, with its 421-foot chimney, went online in 1978.Because it burns costly Number 6 residual fuel, the plant has largely been used as a peaking power plant, fired up only when another big plant goes offline, or when very hot or cold weather spikes the region's demand for energy. With $2 million in annual revenue for the town, it is Yarmouth's largest property taxpayer. In the 1980s, it paid half of the town's tax burden; as of 2012, however, it covered less than 8%.A 16.2 megawatt battery storage capacity was added to the station in 2016.
