Owners considering a re-rig on a Westerly Berwick / Chieftain 31 can use this page to establish the likely project scope before the existing stays are measured. Owners can use the individual sections to compare the core re-rig with optional furler, kicker, winch, rope and mast-or-boom work before requesting a detailed estimate. Two boats of the same model can nevertheless differ after years of owner upgrades, previous re-rigging or changes to the mast and headsail-furling system. Before ordering, compare the model page with the actual rig and resolve any difference in stay layout, wire size, end fittings, pin dimensions, rigging screws or furler connections.
