Aloha Georges,
The Loos gauge uses deflection in lbs in a given length of
shroud. You can do the same thing by measuring the amount of lbs in a certain measurement of deflection for the total
shroud. It may not be perfectly accurate but it will be close.
So, what I do is use a
fish scale and pull the shroud toward the lifeline and see how far it deflects to get the
fish scale up to a certain amount in lbs or kilos. Do the same on both sides of the
boat until you have them nearly equal. Not guitar string taught but not loose either. You do this test while at the
dock. Then take the
boat sailing and see if you have the shrouds tight enough not to be flopping around on the lee side when you are close hauled.
Good luck on your tuning. Thanks for using the term shroud. One of the first questions on our exams is why sailing has a different vocabulary. It is to make ourselves clearly understood.
regards,
