ROCKLAND, Maine — The sale of one of the city’s largest motels has been completed.

Stewart Terrace LLC closed on the deal Nov. 20, buying the Navigator Motor Inn from Robert and Dorothy Liberty.

The limited liability company is affiliated with Maine Course Hospitality Group of Freeport. Peter Anastos, one of Maine Course Hospitality’s owners, said Monday the motel would be closed for approximately six months for renovations.

The hotel will be renamed Rockland Harbor Hotel. The renovated hotel will have 83 rooms.

Maine Course also built the Hampton Inn on Route 1 in Thomaston near the town line with Rockland about 12 years ago.

Anastos said in September that the aim of the work on the Navigator would be to make it “cool and hip,” and a place that would get people’s attention so they would stop and want to stay. He said the restaurant would be removed and a lobby three times the current size created. The remade facility also will include a fitness center for guests and a place for them to have breakfast, he said.

The five-story hotel was built in 1971 on Main Street, also known as Route 1, across from the Maine State Ferry Terminal. The Libertys had owned the Navigator since 2000.

The building and property are assessed by the city at nearly $1.8 million. The sale price was estimated at $1.4 million.

The Libertys still own the Trade Winds Motor Inn in Rockland.
