Interestingly, we sail in a crowded boating area, and I havent seen a spinnaker displayed yet.
We are the only boat that flies one at our lake. I saw another one about 6 years ago. We have a bunch of pretty serious sailors too. Suprising.
I dont consider it to be too mmuch work considering the benefits. We sail on a fairly small lake and consequently cant do long runs yet we fly it near every time we go out. Theres just no feeling like being pulled along that fast by someting as thin as tissue.
Just a sidebar note on edit, There is huge discussions on spinnakers, a-sym and sym in the archives. How to use, rig, repair, buy, sell, sew, conjur and steal. Do a search and youll come up with more than we could jam into a new thread.
