Timely... I set up my rigging per the instructions in the owners manual immediately after launch, and Windstar sat for a few weeks other than a couple of very gentle sails. Finally got to give her a righteous thrashing last weekend and I returned with slack upper shrouds - a bit alarming. Lowers and mids not obviously changed, mast step not collapsing, chainplates not failing. I suspect I had not adequately tightened the uppers. A neighbor explained that his boat changes shape a bit once launched (or rather, sitting on the cradle all winter distorts it a bit.)
Without a gauge, how do I gauge that ensure that the shrouds are tight enough? Deflection? What is it that re-seats and settles when the rig is first set up? Tx.

I have the Loos RT 10 gauge. According to NavTec, the breaking point of the rod is 8,000 lbs. and they recommend not exceeding 25% or 2,000 lbs. in our case for tension of the shrouds. My uppers are normally around 1,300 to 1,350 lbs......the lowers 1,200 to 1,250 lbs...... that equates to numbers on my gauge of around 39 to 40 uppers to 37 to 38 lowers. The rig will always loosen a bit after the mast is stepped and tension first applied.....mine always does. At rest, my backstay tension is around 1,000 lbs.....more when the split backstay is pulled down. The babystay is approx. 500 lbs. My rig has been tensioned this way each year since I got the boat in 2006. Trusting this is helpful. Rob Abbott AZURA C&C 32 - 84 Halifax, N.S.
