Inspecting the sails
When inspecting the sails, what are you looking for, really? According to the great Don Casey book I've been reading, he suggests simply pulling a corner of each sail out of the bag to see what it looks like (and see if there are any frayed stitches, basically). Is that really sufficient?
Also, what's the average life expectancy of Kevlar/Mylar/Dacron? Are 5-year-old Kevlar sails likely to blow out at any moment?
