Spreader (Rigging)

A compression strut projecting from a mast to deflect and support a shroud or stay.

Spreaders increase the angle between mast and rigging so shroud tension can support the mast more effectively. They may be straight or swept, fixed or articulated, and arranged in one or several sets according to the rig.

Their roots, tips, fasteners and shroud retainers carry concentrated loads. Alignment, compression damage, corrosion, cracks and chafe protection require inspection, and a displaced or failed spreader can compromise the mast even when the shroud itself remains intact.
