I ordered my custom outhaul and single line jiffy reefing from Blue Water Yachts today. I tried to piece together my own system but I couldn't beat their price for the kits. And they are designed for the Mac. http://bwyachts.com/web%20catalog%2031203/mainsail%20handling/single_line_reefing.htm http://bwyachts.com/web%20catalog%2031203/mainsail%20handling/custom_outhaul.htm
