I recently bought a used Escape Rhumba with 'smart rigging' (the sail wraps around the mast and has one furling line), which the manufacturer's brochure claim allows for quick rigging, furling, unfurling and partial sail adjustments. I can unfurl the sail but need actually to turn the mast in my hands to furl the sail - the furling line will move the mast as it is supposed to. It look alike I have all the parts, but now I wonder if something is missing. Does anyone have enough experience with this boat to suggest what the problem might be?
