Welcome aboard Shane! I can't say I'm an expert on
singlehanding a spinnaker but when I was young and foolish I had a spinnaker on my little 24 footer, and I did sail with it a number of times alone when I was running home (on the same tack the whole way). I could raise it from the
cockpit of course, once the
sheets, topping
lift and foreguy were all set. And this was all on pretty calm days too. The topping lift and foreguy were rigged back to the
cockpit too of course. It really helps to be able to steer the
boat with the tiller between your legs while you are raising and trimming the sail! That's actually a must-have in my book. No gybing

(unless you take the sail down first). I survived. The sail, the boat, pole and
rigging all survived. It was often VERY fun, but I can't say I'd recommend it. The cruising spinnaker is a better choice as Foolish says IMO. And actually, now that I look back at your post, that's what you were asking about!
