Sigma 33 is an established British sailing yacht, with our model data recording a fractional sloop rig, 9.91 m LOA and produced from 1979 to 1991. On a yacht of this age, model-level specifications are best treated as a reference rather than a manufacturing schedule because the rig may have been altered during earlier re-rigging or equipment changes. For a replacement set, we would check the stay layout, wire or rod material, diameters, finished lengths, mast terminals, chainplate pins and rigging-screw threads. The forestay and any fitted furler should also be confirmed together before anything is made.
