Beneteau First 325

According to Sailboat Data she has a masthead rig (as shown in the drawing below) -

I think that @Concerto has probably replaced the standing rigging on his Fulmar relatively recently as part of his massive re-fit - ok, she is fractionally rigged rather than masthead like the Beneteau, but if he has an approx estimate, it should still give you a useful ball park figure (?)

We’re currently re-doing our 42’ double-spreader masthead (10mm stays and 8mm shrouds) and are doing rather well at £2.5k for the wires/swaging/screws (but this was paid at Dec ‘21 prices). I’ve probably spent close to another £1k on fittings associated with the mast and boat (the above deal was only for the rigging alone). We were then hit with £1200 for new chainplates.

For a boat our size, though, many would probably say we’re not doing too badly at complete ‘new’ rig for around £5k inc. yard fees.
