Consider using this instead of a Bowline for securing a sheet to a jib clew, its more compact than a Bowline and also much more resistant to shaking out. The downside is that, it’s also prone to jam and be much harder to untie. This is the same knot as the 4 in hand knot used for tying neckties. Good for wherever you don’t want to take a chance of the knot coming loose.
