[C320-list] Rig tension

[Dennis Cookson]

Peter, you can find the Loos rigging guide complete with conversion charts at https://ebyoj2gi6ug.exactdn.com/wp-content/uploads/2021/05/INST-07.pdf <https://ebyoj2gi6ug.exactdn.com/wp-content/uploads/2021/05/INST-07.pdf>.

If you are using imperial-sized wires, a PT-2 gauge reading of 31 corresponds to a tension of 720lbs for 1/4” wire.  Anything in the region of 40lbs would be considered to be extremely slack (off the charts).

Regards,

>> My boat came with a Loos model-B that measures in pounds.  I’d like to check the rigging tension is correct.  The conversion charts I have seen don’t seem to make much sense to me.  I measure around 40lbs on the D1/2 and back stays (I can’t measure the cap stays).  Does this make sense?
