I am replacing the existing rope jib/genoa halyard for a wire one, can anyone tell me how to work out the length of wire and a good method of tensioning. I will be cruising and light racing.
Vince W758402/04/2010 at 12:27 pm #9083howardMemberI used what is probably the simplest setup, which is a highfield lever mounted on the mast to tension the wire:
eg http://www.sailboats.co.uk/Catalogue~Holt_Highfield_Lever~p_HA4260~c4752.htmlI used an old wire halyard to measure the length of the wire needed, but positioned the highfield after the wire had been made just to take account of small errors and get the usual tension somewhere in the middle of its range. The only problem was to properly tension the genoa & mast while I measured the length – I put a the setup under proper tension with a temporary block and tackle onto the spinnaker ring on the mast before measuring.
Other tensioning options include muscle boxes or block arrangements usually somewhere near the centerboard case. You may be able to get good tension more easily and/or adjust on the fly. Others are better able to advise on these things.

Rope tail, four mm, pre stretch, three strand so as to make a nice rope eye through the wire soft eye.
Over buy the rope tail,it gets worn fast, so can be respliced at the good end and chopped off at the bad.Wire does stretch some from new so do not be surprised if the rig goes soft,just reset the tension again.
