In spite of what Rick keeps saying, I have been using the jib (with modifications) for 2 years now with success. Mostly in > 10 knot winds. I have used Rick's method for increasing the leach tension (extra block near base of mast plus a cleat on the mast). The main diffence is adding leach clips and replacing the forestay with a non-coated verion (to keep the clips from sticking when raising the sail). The bow spreader is must - although I do NOT attach the jib to that, I have a cable runnning from bow to bow with a triangular "ring" in the middle.

One trip I was out in > 25knot winds with large waves - lowered the main and came screaming back on just the jib!
