Come see the SMF (synchronized main furling) system in action! Sail handling has never been easier, especially for small crews! An in-mast electric motor is synced with an electric winch, the Selden E40i. In-Out control buttons make the push of one button control both motors. Push a button and the sail comes out in a controlled fashion as the winch adjusts the outhaul tension. Push-button sailing has never been easier aboard the new Catalina 6 series.
