Our usual shroud tension is 39-41 which at the high end if off the chart on the Loos gauge. In a breeze I like to add 2-4 full turns on lowers then uppersto 43-44 (a turn at a time on each side switching back and forth). People have been experimenting with rig tension around here, very loose in the light stuff. We used to shorten the headstay 2-6 turns and will if we think the breeze will hold, but generally we don't see too many days on the Cheaspeake with sustained winds over 20.
