I just came across this thread. Looks interesting and I think I'll try it. Zippers of practically any length are available from www.seattlefabrics.com. Reasonable prices and shipping. I bought the plasticMarine version and I think an 11 foot one only cost me $10 plus shipping.Frank - You mentioned in your furler description that you have 20' zippers available at reasonable cost? Are they still available?
Thanks
