FIGHTING CHAFE

The major cause of failure of a mooring strop or bridle is chafe. V-bridles are usually made using 8-plait nylon which is great at absorbing shock loads produced by waves and wind. This dynamic load produces a constant cycle of stretch and recoil in the line, and this abrades the line wherever it touches the boat. Spliced loops should be covered with a sacrificial layer such as polyester tube webbing. Protection should also be added where the rope exits the boat as commonly the line will change angle through a fairlead. The risk of failure due to abrasion or sun damage can be mitigated by choosing a large diameter line that will not be compromised by minor damage.
