Lewis R. French is a gaff-rigged topsail schooner sailing out of Camden, Maine as a "Maine windjammer" offering 3 to 6 night cruises to tourists. Built in 1871, she is the oldest known two-masted schooner in the United States, and one of a small number of this once-common form of vessel in active service. The ship was designated a US National Historic Landmark in 1992.
