Stupid question, maybe: what is a 'code zero gennaker', as mentioned in this month's YM article on the new Najad? How is it set/furled? And do I want one on my Christmas list?
Very light genny, with a luff on something like Spectra - usually set on its own detachable furler ahead of the real forestay. Used for light airs beating/tight reaching with the wind too far forward for a kite or cruising chute. Like this, but not necessarily white.
I would have expected a straighter luff than in the photos - I thought the benefit was being able to pull the luff bar tight to get much more to windward than normal for a gennaker which is limited to about 60 - 70 deg apparent.
