Running Backstay
A running backstay is a rigging component on a sailboat that helps support the mast. It runs from each lateral corner of the stern to the mast at the level where the forestay begins in a fractional rig.
Key functions of a running backstay:
- Mast support: It helps to prevent the mast from bending aft under load, especially in strong winds or when carrying large sails.
- Forestay tension adjustment: By adjusting the tension in the running backstay, you can fine-tune the tension in the forestay, which affects the sail shape and performance.
- Balance: It helps to balance the forces on the mast, especially when using a staysail or other headsails that can create unbalanced loads.
When are running backstays used?
- Heavy weather: In strong winds or rough seas, the running backstay can be tightened to provide additional support to the mast and prevent it from bending or breaking.
- Upwind sailing: When sailing close to the wind, the running backstay can be used to increase the tension in the forestay, which helps to flatten the sails and improve upwind performance.
- Using a staysail: When using a staysail, the running backstay helps to balance the forces on the mast and prevent the staysail from pulling the mast too far forward.
Important considerations:
- Accidental gybe: Because running backstays are attached low on the mast, they can pose a risk in an accidental gybe, as the boom may hit the stay, potentially damaging the boom, mast, or both.
- Proper adjustment: It’s crucial to correctly adjust the tension in the running backstay to avoid over-stressing the rigging and mast.
- Maintenance: Regular inspection and maintenance of the running backstay are essential to ensure its safety and functionality.
Overall, a running backstay is a valuable tool for sailors, providing additional support and control over the rig, especially in challenging conditions.
