AIRX 700N Ripstop 1.1oz White 60"

great cloth for our RC boat sails

I use this in a middle school engineering class as the sail fabric for a miniature sailboat project the students do. It works beautifully--edges don't fray, ripstop grid pattern makes it easy for students to pattern their sails, and dries very fast if they get their sails wet. Never used it for actual spinnaker fabric, can't comment on that part, but I imagine it would work beautifully there for spinnakers on a midrange boat.
