A Carrick Bend ([Fig. 11]) will bend two ropes together more securely than the common bend.
Fig. 11.
When it is desired to fasten one rope on to the middle of another rope, so as to haul upon it, a Rolling Hitch must be used, as this, when jammed, cannot slip down the rope, and yet it is easily cast off again.
[Fig. 12] represents a watch-tackle, with the tail of its upper block bent with a rolling hitch on to the rope it is intended to pull upon, while the hook on its lower block is made fast with a Blackwall hitch.
A watch-tackle is a very handy tackle on board ship, and is used for a variety of purposes. A tail is strapped to the upper block and an iron hook to the lower block.
A very powerful purchase is obtained by using two watch-tackles in combination. This is done by making fast the tail of one watch-tackle to the hook on the lower block of the other tackle.
With a Blackwall Hitch a rope can be rapidly and securely fastened to a hook for a temporary purpose.
