Flying a spinnaker single-handed
I''ve been single-handing symetric chutes for years and have never had any difficulties. I would whole heartedly agree with Jeff on his worries of attaching the tack of the asymetric with the Tacker at the rolled-up genny.
The only thing I add to the symetric equation, I use lazy sheets and guys. On Silmaril, with her large foretriangle, I feel safer that way. A bit more fuss when jibing singlehanded maybe, but doing a dip-pole jibe works better for me with the extra control I feel with them. When I am getting ready to douse the chute, after the guy is released, I bring the clew to the leward mid-ships rail by hauling in the lazy guy, cleating it off, and then gather the chute and drop it down the companionway.
