Socks and the "R" word
I have used an ATN snuffer on our tri-radial chute for many years. It is extremely convenient when sailing short handed. I would also note that the original poster might possibly be misled by the phrase 'symmetrical racing spinnaker'. There is no such thing as a "racing" spinnaker. When you enter a race, All of your sails might as well be called "racing" sails.
Granted, a lot a A-Sails have been sold on the sole basis that they were easy to use and that a standard spinnaker was difficult. (When selling stuff, any narrative that separates $$ from the wallet of the customer is considered OK.) :cry:
It takes some practice and attention to use any "flying" sail. Worth the effort on a light air day, tho!

Fair winds,

One minor quibble....Sorry Mr. Bill....... but I was not aware that sailors used dousing socks on symetrical racing spinnakers. That would be an exceptionally inconvenient piece of gear with sheets, guys, topping lifts and the upwind sails to deal with... besides the pole and the high riding chute.
BTW, a gennaker is an asymetrical sail.
