Stavanger, Friday
The junkette sail looks much like a junk sail, but differs in that the yard and battens terminate at the mast somehow. I guess they all have small yaws pushing against the mast. My reason for not trying it is a fear that one will have added friction, both when raising and when lowering the sail, more like on gaff rigs I have sailed. I would rather make a real junk sail with a high-peaked yard (at least 70°). Then, when the junk sail has been raised conventionally with one halyard, it can be moved aft to minimum balance by hauling on the upper luff hauling parrel (also called throat hauling parrel). You could even make the tack parrel running and haul the tack aft after raising the sail. This will ensure that raising and lowering the sail can be done with the low friction which is typical for junk rigs.
You may have to sacrifice a bit of the jib area, but not much.
Cheers, Arne
PS: I could be wrong of course. You may have found a material for the yaws that has very low friction so that the problem I see is no longer valid. In that case I guess the junkette should work fine - without or with camber added to the panels.
