Halyards, and Sheaves Hello everyone, hope summer gave you plenty of satisfaction. Coming back to a previous thread... On probably most of our boats, the original genoa halyards were mixed textile and steel, and the sheaves were adapted to these with a special shape. Can one use complete textile genoa halyards (spectra, vectran, etc..) without changing the sheaves? If this is the case it would be very helpful, as changing top mast sheaves would be quite an adventure and installing textile halyards a great improvement. Many thanks and fair wind. Philippe. 41/022

Philippe The existing wire/rope sheaves can be expected to eat rope halyards quickly, but the following trick could be tried. Put a protective outer sleeve on the rope halyard for a metre or so in the area where there is contact with the sheave under high load. The sleeve needs to be stitched at the ends to stay in place. Reefing positions would require the same treatment. Sleeves can be taken off a bigger rope having the same core diameter as the rope halyard outside diameter. An eye has to be kept on the chafe situation of the protective sleeve, and replacement done in time. The existing sheaves are probably roughened by the wire, and it could extend the life of the sleeves if the sheaves are smoothened by sanding Have no practical experience of this approach, but sleeves are used for similar purposes in other places Aramid halyards need flat sheave grooves and are not suitable here.

I replaced all of my sheeves from the original textile/wire halyards to sheeves without the wire groove.. It is not a big expense and well worth the effort when considering the potential cost of replaceing a high tech halyard damaged from the wrong sheeve type.
Good Luck |

Thanks a lot for these very unseful replies. Unless I have problems I think I will stick to the original wire/textile genoa halyards, which after all are not that bad. Kind regards. |
