That's indeed what we call that sail here on the "right side up" part
of the world, Walt. The wire inside the luff acts as the "stay", and
the sail does have to come down to change tacks. There is also such a
thing as a mizzen spinnaker, but that isn't what is shown in the pic.
No offence intended, but what the "upside down people" call it is
probably some quaint thing like "boofsmoggler" or "deepilboink", maybe
Oz will enlighten us?
Happy Halloween,
