What is the maximum pressure I can put on my hydraulic backstay adjuster?
The pressure should not exceed 25% of the breaking strength of the wire. Listed below are some breaking strength values for various wires used in the production of Pearson Yachts. It should be recognized that the 25% guideline is a conservative figure but other factors such as hull type, mast height, and sail plan also play a part in the total tension on the standing rigging.
