Just took another look.
The jib does not appear to be self tacking but then I don't
think the Tiger's jib was self tacking first up.

I think the 12ft target audience needs something much simpler to maintain the advantages of the 12 ft size.

Just a personal view.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
