And self-tacking jibs are not exactly a new idea. They are pretty common on cruisng boats. Our old Irwin 37, which was already old when we got it in 1982, had a self-tacking jib in addition to the genoa.

And, as I recall, the original Nacra 6.0 had a self-tacking jib, back in the 1980's. Didn't work very well performancewise, so it was scuttled when the NA version came out.
