Try looking under weathervanes. I would think you could make 1 from copying a simple pattern from Internet or coloring book. Make sails of sheet copper mounted on copper heavy wire so they would move in the wind. Boat of wood painted or shaped from copper sheeting, available at hardware store. mount on post or roof of garage or house. Can make any size you want. Could emboss the sails with your monogram if you wanted or just a design.
