My first spinnaker....
was on my O'Day 222 a dozen years ago. I'd gotten so comfortable sailing the boat that I had an asymetrical custom made, including the sock for dousing. In response to your question, you need to be really comfortable handling your boat presently as flying the spinnaker is going to keep you really busy - you shouldn't have to think about the routine sailing of your boat, it should be automatic - so that you can concentrate on what is needed to keep the chute full. On the other hand, it can make for really exciting sailing, so if you think your skill level is up to it, by all means go for it. Rigging an asymetircal requires a spinnaker halyard, and blocks attached as far astern as possible on each side for the sheets. The sheets run from the sail to each block and then up to your jib winches. I recommend your sheets be long enough that the unused sheet goes all the way around the boat. That enables you to jibe the spinnaker (you don't want to come about with the chute up but jibing is easy) without leaving the cockpit. I also modified a sail bag so it attached to the bow pulpit, and the spinnaker in the sock could be stowed in it fully attached the the halyard and downhaul, and sheets all in place before leaving the dock. Hoisting the sail simply involved hauling it up and out of the bag by the halyard, and then raising the sock when ready. Dousing was the reverse - pull the sock down over the sail, then release the halyard and stuff the sail/sock back into the bag as it came down. It could stay right there on the bow pulpit until needed again or until returning to the dock. I'm now entering my third year with my H 29.5 and Santa delivered a Doyle APC which I am looking forward to using it this season. Good luck with yours.
