    I have the use of a rig tension gauge with the idea of re tensioning my rig.
    My headsail furler seems a bit saggy and I have nealy used up all the threads of the adjustable back stay tensioner.
    Has anyone got the info on rig tension?

    Please use the search funtion. as this has been covered so many times before.
    here is a copy of Vyv’s info.
    See my guide to standing rigging setup at https://coxengineering.sharepoint.com/Pages/Standingrigging.aspx My 34 rig has been set up using this method for many years. Last year I borrowed a Loos gauge during the replacement of a chainplate, also on my website, and found that the tensions achieved by my method were spot on as measured by the gauge.

    The figures I measured were:
    Starboard: Cap shroud 13%, Lower 9-10%
    Port: Cap shroud 10%, Lower 9-10%
    Babystay 14%
    Backstay 20%

    These are all within the range quoted for masthead rigs.

    not quite sure what you mean in percentages regarding the settings.

    The figures are the extension from the original length. This is the method the Loos gauge uses.

    I have a gauge that distorts the wire and is calibrated in % of breaking strain.
    Depends what gauge you intend to use.
