Have you seen the spinnaker fulrer setup on the Marstorm M20? It's a snail-shaped shell with a roller drum inside, all mounts just in front of the mast. The roller is parallel to the front beam and the snail opening faces towards the front. Though I've not seen it up close, it must have a line to roll the roller and spool in the spinny. Has the advantage of being extremely compact, low windage and fast (perhaps faster than a snuffer).
Looks real Wiz-Bang with the fancy snail shape made from Carbon. From thinking more about how it works, one could likely be fashioned out of an old plastic bucket. Heck, you could even do away with whole shell completely and just run a snuffer-style hoop (mouth) at the front to feed the sail onto a horizontal roller drum.
