Sail technology: Seldén SMF: Set sails at the touch of a button - easy to retrofit

A furling mast makes sail handling much easier, but the outhaul and reefing line must be operated simultaneously for optimum function. This requires two winches and a correspondingly large number of hands. The SMF system from Seldén promises significantly more comfort. The abbreviation stands for Synchronised Main Furling, i.e. the outhaul and furling mast drive are controlled automatically so that only one button needs to be pressed to furl and unfurl.

Selden's synchronised furling system in practice

The system includes an electric mast drive and the newly developed E40i three-speed electric winch. Thanks to the internal motor, it requires only one space below deck. The associated control unit regulates the speed of the outhaul winch relative to the mast drive so that the mainsail is unfurled cleanly and without killing. As the electric winch cannot run in reverse, the outhaul must still be furled manually for reefing.

Convert Selden roller mast to electric drive

The system is suitable for yachts between 36 and 43 feet and can be retrofitted to all furling masts in the RB series. The conversion package for the mast costs around 3700 euros. The E40i winch is available for 2250 euros with an aluminium drum; the stainless steel version costs 2400 euros. If you want the complete system, you should contact a Seldén service centre.
