Hat to bring this up again BUT...I received by Loos gauge this week and will be going this weekend andas I sit at anchor thought I would tweat the stays. I've seen 940, 470 used as a bench mark for tuning but I'm unsure. Mymanual does not give anything in the way of tuning the rigging just size ofthe steel. If you look at url ->http://www.ayesail.net/sailing/Hunter/ManualH260/Page47B.htmRD1 is 1/8" and I have no idea what to set this to????D1 is 5/32", the lower stay.V1 and D1 5/32" make up the upper stay.Hope I have the correct! From what I've read on this site, I should beclose to the 940, 470 numbers, if I don't get to scared.Advise Please!!Jim S/V Java
