I need to replace my forehalyard. Does anyone know whether it should be 3 or 4mm wire? I cannot make it out from my current halyard and am not currently near the boat to try again before I need to order.
You do mean the genoa halyard? 3mm, 7×19 S/S. Hard eye for genoa end and soft eye for tension end. I like to have a shortened, shroud chain plate plastic cover on the halyard at the genoa end put on the wire before the hard eye is done. I use this to cover the wire to genoa shackle so it does not rip the sails up aloft.
