How to Tie the Blackwall Hitch Double Blackwall Hitch - Attaching a Load to a Crane Hook
I am not sure, but I may be wrong, I would think that in this day and age the Blackwall Hitch is more of a novelty. In the days before health and safety the Blackwall Hitch was a way of attaching a load to the hook of a crane. It is such a simple hitch and it is only due to the crossing point on the crane hook that the load is locked tight.
I would also suggest the the Double Blackwall Hitch is not much more secure than the single version. Whilst the line around the hook is under tension, the hitch remains locked in place. Once the line is allowed to become slack, it is all to easy for Blackwall Hitch to come loose or free from the crane hook.
*Ashley's Book of Knots:*
1875. The Blackwall Hitch is given by Steel in 1794. It is used in setting up rigging when the lanyard is short, but is never quite safe unless the rope is large enough to nearly fill the mouth of the hook. It should never be tied to a cargo block.
1876. The Double Blackwall Hitch has one more turn and is often recommended as preferable to the former knot. It appears, however, to be even less reliable. The second turn is sometimes jammed below the first in the manner of the Awning Knot, but this appears to be no improvement.
