I normally carry a loose rig when not trapezing. This is tested by grabbing the leeward shroud with your hand and turning it to 120 degrees. As the breeze freshens, I tighten the rig to keep the leeward hull from depressing too much. This is very important to remember in choppy water. While trapezing, adjust the shroud tension to 45 degrees using the same method as above. This will keep the rig powered up and not dump you in the water in lulls.
