Hi Bernd,
There is no sprit on the Wharram wing sail, just a short gaff which is not heavy made in laminated ply. Obviously carbon would be lighter. The gaff lives in a sleeve at the top of the sail and stays there when the sail is furled. I had a full length zip on the sleeve, but it was only useful for fitting/removing the sail at the beginning/end of the season. Having the zip actually made the sail stiffer to fold down.
PS I went for the wing sail because I didn¡¯t fancy the standard sprit rig for the reasons you mention.

?Short. A bit complicated to set the sail on the Wharram. Setting first the sail and fastening the boom (sprit)?
Can be dangerous when you have to shorten sail in bad weather.
We overcome this by setting the Wishbone on a double rope on the Butterfly.??
It is known that it is hard to set a sleeved sail.?
We overcome this by using a sleeve that can be opened with a zipper.?
Cheers
