The Academy also operates a 88-foot, 66-ton wooden sailing schooner, the Bowdoin, which was launched in 1921. Under the command of Admiral Donald MacMillan, one-time Castine resident, she made 26 voyages of exploration to the Arctic. A National Historic Landmark, the Bowdoin is the flagship of the Maine Maritime Academy sailing fleet, and carries dual certification from the U.S. Coast Guard for any ocean as a sail training vessel and small passenger vessel.
