SMF – Synchronized Main Furling
A retrofitable motor in the furling mast is synchronized with the E40i winch. The mast motor feeds out the sail while the electric winch is tensioning the outhaul. All is controlled by the push of a single button. The speed of the E40i winch is automatically adjusted to the load in the outhaul. If the load exceeds a certain level, the winch will reduce its power to avoid overload. To furl the sail back in to the mast the outhaul is released while pushing a button.
