appendage
A fin—the centerboard, keel, rudder, or skeg—under the boat that helps with steering and provides lateral resistance (and provides ballast, in the case of the keel). Most keels and skegs are fixed in place, while centerboards are retractable and rudders turn. Appendages usually have foil shapes to improve the flow of water around them and to provide lift.
