Re: Shroud and stay tension when climbing the mast
Why are you loosening shrouds? Are you worried that your extra weight will overstress the deck where the mast is mounted?
Don't worry about it. If your shroud lines are adjusted correctly, you mast is already in compression to the tune of several thousand pounds (generally, 1/4" forestay and backstay generally tightened to 1300 lbs each, 1/4" upper shroud tightened to 820 lbs, fore and aft 1/8" shrouds each at 240 lbs). So your weight is a miniscule addition.
Moreover, when sailing in a stiff breeze, the loading increases... by more than your body weight.
