Diamond tension

Estimated reading time: 1 min
Tools needed:
– Wrench 17 mm
– “Loose” tension gauge

Steps

1. Put tension on the diamond wires by tensioning the diamond adjuster bolt with a wrench size 17mm. Use the “loose” tension, or an equivalent gauge to measure the tension on the diamond wires.
2. After putting tension on the mast check if the mast is straight. Take a look along the sail groove from mast base to mast top.

If the mast is bent to starboard:
1. Release the diamond tension
2. Detach the port diamond wire at the tang and shorten the wire with 1 full twist clockwise.
3. Attach the port diamond wire at the tang and put tension on the diamond adjuster bolt again. Redo this process if necessary
