A: Sure, you could easily add something to hang these sailboats from a tree or mount it on top. In fact, the sailboat mast is pretty well centered, so it should hang straight.
It is larger than most ornaments at 7” tall, but not too heavy for hanging, about 2 oz. You could even add mini fake Christmas lights, a wreath on the sail, or a Santa at the helm.
In addition, we do carry Christmas ornament sailboats.
