I was going through two spinnakers and one jib a year, then a main every couple of years. That was when the Hobie Tiger was making the spinnaker out of a very light and seemingly stretchy material. At that time I was sailing most weekends and a couple of evenings during the week. I now have two spinnakers That have lasted more than a season. One is only used for racing. The other I use for pleasure sailing. I think the newer materials last longer but will probably try to get a new chute for the NAs.
