Snatch blocks are a very versatile piece of sailboat hardware that can be used pratically anywhere on the boat. A snatch block is a specialty block (also known as a pully) that has one of the cheeks open. This enables snatch blocks to be placed on loaded lines, or on lines that the bitter end is unavailable. Having snatch blocks on board gives your crew options in expected and unexpected situations, such as headsail changes or failure of other blocks.
Snatch blocks are commonly used in head sail handling appliactions. A common use for snatchblocks is as tweakers on spinnaker guys. Using a snatch block on a tweaker allows for efficient headsail changes and makes it easy to remove the tweakers in light wind. Other uses for snatch blocks includes attaching them to a toerail to use as a lead for a genoa or spinnaker sheet or adding them to a genoa sheet to use as a barber hauler.
Snatch blocks typically have a lower working load than traditional blocks of the same size so it is important to pay attention to the loads that will be applied when selecting a snatch block. Also note that the load applied to a block changes with the deflection angle.
