You can, but you are going to work for it. Pick a day when the water is relatively calm but there is some wind. You are going to need the assistance of a steady helmsman. Remove the clips and with the boat heeled over in a steady course tighten the shroud until you eliminate the slack. Repeat the tightening on the opposite shroud in an opposite tack. If you cannot acquire a significant degree of heel you may have to repeat the exercise on a windier day. Give it an extra 5 turns to each side for good measure. To make sure we are on the same page the upper shroud you refer to is the one that runs from the top of the mast to the spreader and down to the outboard deck.I have a 1984 H27, My upper shrouds slacken quite a bit when heeled over. Is there a rough way to tension them without a gauge?
you have to help me with that Shemandr.It's not a boat dependent number. It's wire dependent.
if the forces violently change it shock loads the lee standing rigging.My H22 has quite a bit of slack on the lee when heeled over.
what is the harm to this?
