Winchers
They work great. But They do not make your winches self tailing.I put them on my last boat, a Glouchester 22 with a 150 genoa on a furler. The winchers hold the sheets in their groove without any slipping. Once you have the sail sheeted the way you want it, you just wrap the sheet in the wincher groove. Also works well if you want to uncleat the sheet in a hurry. I completely quit using my cleats.They take a little muscle to install because they are such a tight fit on the winch. On my first try, one sprung out of my hands into the drink. Easiest to use 2 people.I currently have a 28.5' boat with ST winches for the sheets but I also have in-mast furling and the furling winch has a wincher. I do not need the holding function but the wincher enables me to use the winch as a sort of ST. If you put enough wraps around the winch, in my case 4, you can get away without continusously tailing the line. The down side is that since there is not a stripper like on a real st winch, the line will continue to wrap itself around the winch unless you pull it out as you crank.If you currently have to fool around securing your sheets to a cleat, get the Winchers.Good LuckBill
